Use the atm abr-mode global command on ABR connections to select efci marking, relative-rate marking, or both. To assign the default value to ABR mode, use the no form of this command.
atm abr-mode {efci | relative-rate | all}
efci | When cells arrive on ABR connections to a congested (as indicated by efci threshold) output queue on the interface, the efci bit in the cell header is set. |
relative-rate | When a backward RM-cell is received on an ABR connection on an interface (from outside the switch), its congestion-bit is set if the forward-direction interface abr-ubr output-queue is congested (as indicated by the abr relative-rate threshold). |
all | Indicates both efci and relative-rate modes of congestion notification. |
relative-rate
Global configuration
This global configuration command changes the global type of notification used on ABR connections to send a congestion alert to the end stations. This change can be made if the switch connects to a network or end station that uses the new technique. The use of all causes both efci and relative-rate marking to be used.
If the ABR/UBR output queue of the forward-direction interface of the connection is congested, using the relative-rate argument marks a backward RM cell on an ABR connection when it is queued to the ABR/UBR output queue of the backward-direction interface.
In the following example, the abr mode of the switch is set to efci.
Switch(config)# atm abr-mode efci
To subscribe an interface or subinterface to an existing ATM address pattern-matching filter expression, use the atm access-group interface configuration command. To delete an address access filter subscription on a specified interface of subinterface, use the no form of this command.
atm access-group name [in | out]
name | The filter expression or filter set. · in indicates you should apply the filter to an incoming SETUP message. · out indicates you should apply the filter to an outgoing SETUP message. |
Out
Interface configuration
This command affects ATM signaling SETUP requests received or transmitted by the switch on an interface.
You should use the atm filter-set command prior to using this command. Filter sets and expressions are described in this manual in the descriptions for the atm filter-expr, atm filter-set, and atm template-alias global configuration commands.
Each interface has only one access group. If you create a new access group, it overrides any existing group.
The following is sample output from the atm access-group command.

To assign a 20-byte ATM address to the switch, use the atm address global command. To delete a specific ATM address, use the no form of this command.
atm address address-template
address-template | The address template can be a full 20-byte address or a partial 13-byte prefix followed by an ellipsis (...). When a partial address is assigned, this command automatically sets one of the switch's 6-byte MAC addresses in the ESI part and puts a 0 in the selector part. |
When no atm address has been configured, an autoconfigured ATM address is assigned. Refer to the LightStream 1010 ATM Switch User Guide for more information.
Global configuration
You can have multiple ATM addresses. When you delete the most current address, the next address becomes available.
In autoconfiguration mode, the switch establishes an address according to the format specified in the software configuration guide.
The first 13-byte prefix of this address is used by ILMI to assign addresses to end stations connected to the UNI ports (unless there is a prefix assigned per port). PNNI also summarizes this prefix automatically in reachable address advertisements. Refer to the auto-summary command for more information.
For two switches to belong to the same PNNI peer group, they need to have the same peer group identifier. Peer group identifiers must be prefixes of private ATM addresses, which means the organization that administers the peer group has assignment authority over that prefix (refer to the LightStream 1010 ATM Switch Software Configuration Guide for more information).
In autoconfiguration mode, all switches have the same peer group identifier based on the first 7 bytes of the autoconfigured ATM address.
The first 13-byte prefix is also used to automatically generate ATM addresses for each ATM interface that can be used for soft PVCs and PVPs to identify the destination ATM interface.

To enable the switch to engage in address registration on an interface using the Integrated Local Management Interface (ILMI) protocol, use the atm address-registration interface configuration command. To disable ILMI address registration functions on an interface, use the no form of this command.
atm address-registrationThis command has no keywords or arguments.
Enabled
Interface configuration
This command does not apply to the ASP 2/0/0 interface.
This command enables a switch to participate in ILMI address registration. When the switch is on the network side of a UNI, the switch sets one or more network prefixes on the peer IME and accepts addresses registered by the peer IME. When the switch is on the user side of a UNI, the switch registers ATM addresses with the peer IME. If the interface does not come up as a UNI, then ILMI address registration is not active, even if it was previously configured to be enabled.
The following example disables ATM address-registration on ATM interface 1/0/0.
Switch(config)# interface atm 1/0/0
Switch(config-if)# no atm address-registration

To identify an ATM Address Resolution Protocol (ARP) server for the IP network or set time-to-live (TTL) values for entries in the ATM ARP table, use the atm arp-server interface configuration command.
atm arp-server [self [time-out minutes] | nsap nsap-address]
self | (Optional) Specifies the current switch as the ATM ARP server. |
time-out minutes | (Optional) Number of minutes a destination entry listed in the ATM ARP server's ARP table is kept before the server takes any action to verify or time out the entry. |
nsap nsap-address | (Optional) Network service access point (NSAP) address of an ATM ARP server. |
The ARP server process is disabled. The default timeout value is 20 minutes.
Interface configuration
If an NSAP address is specified, the ARP client on this interface uses the specified host as an ARP server.
Multiple ATM ARP servers can be specified by repeating the command. The no option is used to remove the definition of an ATM ARP server. If self is specified, this interface acts as the ARP server for the logical IP network.
The ATM ARP server takes one of the following actions if a destination listed in the server's ARP table expires:
This implementation follows RFC 1577, "Classical IP over ATM."
To enable or disable ILMI auto-configuration, use the atm auto-configuration interface configuration command. To disable this feature, use the no form of this command.
atm auto-configurationThis command has no arguments or keywords.
Enabled
Interface configuration
This command enables or disables ILMI auto-configuration procedures, as specified in Section 8.3.3 of the ATM Forum ILMI 4.0 Specification.
Among the variables covered by ILMI auto-configuration are the interface protocol and version, interface side (user or network), UNI type (public or private), and the maximum number of VPI bits and VCI bits. Configuration of the atm auto-configuration command on an interface overwrites any previous configuration of the atm iisp, atm nni, atm uni, atm maxvci-bits, and the atm maxvpi-bits commands.
This command takes effect after the interface is administratively shutdown (using the shutdown command) and the interface is restarted.
When the peer switch has a device type of node but responds to GetRequest messages for atmfAtmLayerNniSigVersion with noSuchName, the default NNI protocol depends on the ATM routing mode (see the atm routing-mode command). When the ATM routing mode is set to static, the default NNI protocol is IISP. Otherwise, the default NNI protocol is PNNI 1.0. These defaults are relevant when the peer switch is a LightStream 1010 ATM with software version 11.1.
The following example shows how to enable ILMI auto-configuration on interface ATM 0/1/2.
Switch(config)# interface atm 0/1/2

transmit | The configured parameter applies to the flow of traffic out of the switch on the interface (or from the ASP 2/0/0 interface). |
percent | The percent of interface bandwidth, from 0 to 95 percent. |
cbr | The constant bit rate connection. |
vbr | The variable bit rate connection. |
abr | The available bit rate connection. |
ubr | The unspecified bit rate connection. |
rate | A positive integer, measured in kilobits (kbps) per second, in the range of 0 through 910533065. |
conn-value | The number of best-effort connections allowed on the interface (0 through 32768). |
cell-count | The limit parameter used in the GCRA policing algorithm (cell-count expresses cell times in the range 0 through 2147483647). |
No link-sharing, best-effort limits, or parameter limits.
Interface configuration
You can configure the link-sharing parameter only on physical ports 0 or 6 on a 25-Mbps PAM.
The atm cac commands provide the ability to tune parameters used in the Connection Admission Control functions performed by Resource Management. The three types of parameters, which are configured per interface, are described in Table 2-3. Any changes made to these parameters only affect subsequent connection setups.
| Parameter | Description |
|---|---|
controlled link sharing | Specifies the minimum and maximum bandwidth that can be allocated to guaranteed service (CBR or VBR) connections. Maxima can be specified for CBR, VBR, and the aggregate of CBR and VBR. Minima can be specified for CBR and VBR. These parameters, for a direction, are interrelated as follows (assuming these parameters are defined):
|
traffic parameter limits | Specifies maximum traffic parameters (peak-cell-rate, etc.) that are allowed on VC setup. These can be specified independently by service category and traffic direction. |
best-effort connection limits | A limit on the total number of ABR and UBR connections on the interface. |
For UBR connections, cell rate is not checked in CAC. By specifying a peak-cell-rate limit, CAC rejects connections that exceed the limit.
The following commands are a subset of the interface configuration and are supported for the subinterface configuration.
atm cac best-effort-limitThe following command is not supported for the subinterface configuration.
atm cac link-sharingIn the following example, a peak-cell-rate traffic parameter limit of 3001 kbps is defined for ABR connections in the receive direction on the interface.
Switch(config-if)# atm cac max-peak-cell-rate abr receive 3001
In the following example, the maximum bandwidth that can be allocated to VBR connections in the transmit direction on the interface is limited to 61 percent of the total bandwidth.
Switch(config-if)# atm cac link-sharing max-bandwidth vbr transmit 61
In the following example, the number of best-effort connections allowed on the interface is limited to 200.
Switch(config-if)# atm cac best-effort-limit 200
To create a table entry, use the atm connection-traffic-table-row global configuration command. To delete an entry, use the no form of this command.
atm connection-traffic-table-row [index row-index] cbr peak-cell-rate rate [tolerance
row-index | Is an integer in the range of 1 through 1073741823. |
rate | Is a positive integer, measured in kilobits (kbps) per second, in the range of 0 through 910533065. |
cell-count | Is used with tolerance and is the limit parameter used in the GCRA policing algorithm. It is an integer, with a range of 0 through 2147483647. The tolerance is expressed in cell-times (2.72 microseconds at 155.2 Mbps). For peak-cell-rate policing on cbr and ubr connections, the tolerance value is CDVT. For sustained-cell-rate policing on vbr-rt and vbr-nrt connections, the tolerance value is the maximum burst size. |
Rows 1 through 6 in the table are predefined.
Global configuration
This command sets up the traffic characteristics used in PVC definition. The characteristics are stored as rows of a table. The row index is referenced when a PVC is created using the atm pvc interface command.
When the atm connection-traffic-table-row command is issued, without the index clause, software uses a free row-index, which is displayed to the user if the command is successful.
When the tolerance parameter is not specified in the creation of a row, a default value is chosen by software to use if UPC is enabled.
Six connection traffic table rows are defined by default and are numbered 1 through 6. Row 1 is the default row used by the atm pvc command if no rows are explicitly specified. Rows 2 through 6 are used for well-known vcs on a vp tunnel subinterface, depending on the service category of the underlying vp. Default rows cannot be deleted.
Row 1 PCR represents the maximum-signallable cell-rate (the maximum cell-rate that fits in 24 bits).
In the following example, a cbr Connection Traffic Table row is defined with index 200 and a peak-cell-rate of 7,743 kbps.
Switch(config)# atm connection-traffic-table-row index 200 cbr peak-cell-rate 7743

show atm connection-traffic-table
To change the default tolerance to request for UPC of cells received on the interface for connections that do not individually request a tolerance value, use the atm default-tolerance interface configuration command. To reset the default tolerance for a particular service category to the default value, use the no form of this command.
atm default-tolerance [cbr | vbr-rt | vbr-nrt | abr | ubr] num
num | The limit parameter used in the GCRA policing algorithm. This parameter is an integer, with a range of 0 through 2147483647. The tolerance is expressed in cell-times (2.72 microseconds at 155.2 Mbps). For peak-cell-rate policing on cbr and ubr connections, the tolerance value is CDVT. For sustained-cell-rate policing on vbr-rt and vbr-nrt connections, the tolerance value is the Maximum Burst Size. |
1024
Interface configuration
Tolerance can be specified for PVCs through a connection traffic table row. If no tolerance is specified in the row then a per-interface, per-service category default tolerance is applied for purposes of UPC on the connection. This command allows for changes to this default.
For signalled connections (SVC or Soft PVC), VBR tolerance (maximum burst size) can be signalled, but CBR/UBR tolerance cannot be signalled. The defaults specified on the interface are used.
The following example shows changing the default tolerance for received cells on VBR-RT connections.
Switch(config-if)# atm default-tolerance vbr-rt 4000

To configure the native E.164 address of an ATM interface, use the atm e164 address interface configuration command.
atm e164 address e164_address
e164_address | Specifies a native E.164 address, consisting of 7 to 15 decimal digits. Refer to the ITU--T Recommendation E.164 for more information on the syntax and semantics of native E.164 addresses. |
Interface configuration
Use this command to configure a native E.164 address used to connect to public networks.
When outgoing calls are configured to use forwarding E.164 addresses as the called party address (see the atm route command), this E.164 address is used as the forwarding calling party address.
When incoming calls are received on this interface that specify this E.164 address as the called party address, the received called and calling party addresses are removed from the signaling message and replaced by the received called and calling party subaddresses as the new called and calling party addresses.
This address is not registered with routing since it is only used as this switch's address for this interface. It is not used as the address of destinations from this interface.
Note that this address is not used in conjunction with the E.164 translation table feature. The E.164 translation table should only be used when you want a one-to-one correspondence between the NSAP-format ATM end system address and the native E.164 address, for example when the public network does not support transport of subaddresses. The combination of the atm e164 address command and the e164 address option of the atm route command provides a general mechanism for interconnection of private networks across a public network. This combination allows one native E.164 address for the interface to the public network, with many NSAP-format ATM end system addresses present in the private network behind the interface.
The following example shows setting the native E.164 address of ATM 0/0/1 to 1341457.
Switch(config)# interface atm 0/0/1
Switch(config-if)# atm e164 address 1341457

show atm vc
To configure an interface to use the ATM E.164 translation table, use the atm e164 translation interface configuration command.
atm e164 translationThis command has no keywords or arguments.
Interface configuration
The ATM E.164 translation table is used when a one-to-one translation between NSAP-format ATM end system addresses and native E.164 addresses is desired. This method for support of native E.164 addresses might be useful when the ATM interface connects to a public network that does not support transport of subaddresses.
Note that the more general mechanism for interconnection to E.164 public networks involves use of the atm e164 address command and the e164-address option of the atm route command. This other mechanism allows one native E.164 address for the interface to the public network, with many NSAP-format ATM end system addresses present in the private network behind the interface.
When a signaling message attempts to establish a call from an interface configured for ATM E.164 translation, the called and calling party addresses are initially in NSAP format. Using the ATM E.164 translation table, an attempt is made to find the E.164 addresses corresponding to the NSAP addresses. These E.164 addresses are placed into the called and calling party addresses and the original NSAP addresses are placed into the called and calling party subaddresses.
When a signaling message is received on an interface configured for ATM E.164 translation, the called and calling party addresses are in E.164 format. If the original NSAP formatted called and calling addresses have been carried in subaddresses, then those addresses are used to forward the call. If subaddresses are not present, due to the network blocking the subaddresses, or the switch at the entry to the E.164 network not providing subaddresses, an attempt is made to find a match for the E.164 addresses in the ATM E.164 translation table. If there is a match, the NSAP addresses corresponding to the E.164 addresses are placed into the called and calling party addresses. The call is then forwarded using the NSAP addresses.
The following example shows setting interface ATM 0/0/1 to use the E.164 translation table.
Switch(config)# interface atm0/0/1
Switch(config-if)# atm e164 translation

To start ATM E.164 translation configuration mode, use the atm e164 translation-table global configuration command.
atm e164 translation-tableThis command has no keywords or arguments.
Global configuration
Use this command to start ATM E.164 translation configuration mode.
The ATM E.164 translation table is used by all interfaces configured with the ATM E.164 translation functionality. Each entry in the table specifies a one-to-one correspondence between a native E.164 address and an NSAP-format ATM end system address.
Refer to the atm e164 translation command for more information and usage guidelines about the ATM E.164 translation feature.
The following example shows starting ATM E.164 translation configuration mode.
Switch(config)# atm e164 translation-table
Switch(config-atm-e164)# e164 address 1112222 nsap-address 11.111122223333444455556666.112233445566.11

To enter the end station ID (ESI) and selector byte fields of the ATM NSAP address, use the atm esi-address interface configuration command. The NSAP address prefix is filled in via ILMI address registration from the ATM switch. The no form deletes the end station address.
atm esi-address esi.selector
esi | End station ID field value in hexadecimal; 6 bytes long. |
selector | Selector field value in hexadecimal; 1 byte long. |
No end station ID is defined for this interface.
Interface configuration
This command only applies to the ASP interface and subinterfaces.
The NSAP-format ATM end system address of an interface is used by static maps (see the section "SVC Based Map-List Configuration" in the LightStream 1010 ATM Switch Software Configuration Guide) and by Classical IP over ATM, as defined in RFC 1577 (see the section "Configure Classical IP over ATM in a SVC Environment" in the LightStream 1010 ATM Switch Software Configuration Guide).
The NSAP-format ATM end system address of an interface can be configured using either the atm esi-address or the atm nsap-address command. Configuring a new address on the interface overwrites the previous address. The atm esi-address and atm nsap-address commands are mutually exclusive. Configuring the switch with the atm esi-address command negates the atm nsap-address setting, and vice versa.
The atm esi-address command allows you to configure the ATM address by entering the ESI (12 hexadecimal characters) and the selector byte (2 hexadecimal characters). The ATM address prefix (26 hexadecimal characters) are provided by the ATM switch (refer to the atm address and atm prefix commands for more information). The resulting ATM address is registered on the ATM switch using ILMI address registration.
The following example sets the ESI to 303132333435 and the selector byte to 36 on ATM interface 2/0/0.1.
Switch# interface atm 2/0/0.1
Switch(config-subif)# atm esi-address 303132333435.36

To configure an ATM address filter that matches patterns, use the atm filter-expr global configuration command. To delete the specified filter, use the no form of this command.
atm filter-expr name term
name | The name of the pattern-matching filter expression. |
term | Can be any of the following: · a previously defined address pattern-matching expression · a filter set applied to calling-party address---source <filter-set name> · a filter set applied to called-party address---destination <filter-set name> |
Permit
Global configuration
The first form listed defines a simple filter expression that is pattern-matched only if the pattern given by term is matched.
The second form defines a filter expression that is pattern-matched only if the pattern given by term is not matched.
The third form defines a filter expression that is pattern-matched if either of the patterns given by the two terms are matched.
The fourth form defines a filter expression that is pattern-matched only if both of the patterns given by the two terms are matched.
The fifth form defines a filter expression that is pattern-matched only if one of the patterns, but not both, given by the two terms is matched.
For commands with two terms, that is, commands using logical operators or, and, and xor, the evaluation sequence is from left to right of the expression. Further, for commands using logical operators or and and, the evaluation for the second term is conducted only when necessary, that is, the evaluation for the second term is omitted if the truth or falsehood can already be concluded from the evaluation for the first term.
The following is sample output from the atm filter-expr command.
Switch(config)# atm filter-expr atm_filter_expr1 not source atm_filter_set1
Switch(config)# atm filter-expr atm_filter_expr2 source atm_filter_set1 and destination atm_filter_set2
To create an ATM address filter set, use the atm filter-set global configuration command. To delete the specified filter, use the no form of this command.
atm filter-set name [index number] [permit | deny] | {template | time-of-day
name | The name of the filter set. |
index | Set order in which filters are set. The range is from 1 through 65535. Default is 1. |
permit | Permission to accept an incoming call or forward an outgoing call on an interface/subinterface if the address pattern-matching succeeds. |
deny | Denial to accept an incoming call or forward an outgoing call on an interface or subinterface if the address pattern-matching succeeds. |
template | An ATM address, address template, or an ATM address template alias. |
time-of-day | Specify the time range in which the filter-set takes place. This parameter can be specified as anytime or as a specific time. The default is anytime. |
start-time | Specify the time the filter-set starts, in 24-hour format, hh:mm:ss. |
end-time | Specify the time the filter-set ends, in 24-hour format, hh:mm:ss. |
Permit
Global configuration
If neither permit nor deny is specified, permit is assumed. If an address does not match any of the filter set entries, an implicit "deny" is returned as the permit/deny action of the filter set.
Filters are set in the same order they were configured. You can change the order (except in a complete NSAP address that has no wildcards) by specifying the optional parameter index.
After you create a filter for a specific interface, associate the filter to that interface by using the atm access-group command.
The following is an example of the atm filter-set command.
Switch(config)# atm filter-set filter_set1 permit 47.0091.8100.0000.0003.bbe4.aa01.4000.0c80.0000.64

To disable idle timeouts entirely, set the value of seconds to zero.
To configure ATM IISP (Interim Interswitch Signaling Protocol) on the specified physical or logical (VP tunnel) port, use the atm iisp interface configuration command.
atm iisp [side side] [version ver]
side | Specified as user | network. The default is network. |
ver | Specified as 3.0, 3.1 or 4.0. |
Interface configuration
Refer to the LightStream 1010 ATM Switch Software Configuration Guide for more information about this command.
Before using this command, the interface must be administratively shut down (see the shutdown command) and ILMI auto-configuration mode must be disabled (see the atm auto-configuration command).
The atm auto-configuration, atm iisp, atm nni, and atm uni commands are mutually exclusive. Configuring atm iisp command overwrites any previous configuration of the atm nni or atm uni commands for this interface. Future configuration of the atm auto-configuration, atm nni, or atm uni command on this interface overwrites the atm iisp command.
In order for calls to be routed from this interface, one or more static routes must be configured (see the atm route command).
The following example configures ATM interface 3/1/2 as an IISP interface, running version 3.0 as the user side.
Switch(config)# interface atm 3/1/2
Switch(config-if)# shutdown
Switch(config-if)# no atm auto-configuration
Switch(config-if)# atm iisp side user version 3.0
Switch(config-if)# atm maxvci-bits 12

To enable the ILMI on a port, use the atm ilmi-enable interface configuration command. To disable the ILMI, use the no form of this command.
atm ilmi-enableThis command has no arguments or keywords.
Enabled
Interface configuration
This command does not apply to the ASP 2/0/0 interface.
ILMI is enabled by default; however, if the peer does not support ILMI, you should turn off ILMI using this command.
This command takes effect after the interface is administratively shutdown and then restarted using the shutdown command.
Several components of ILMI can be disabled independently without completely disabling ILMI. Refer to atm address-registration, atm auto-configuration, and atm ilmi-keepalive commands for more information.
The following example shows how to enable ILMI on interface ATM 0/1/2.
Switch(config)# interface atm 0/1/2
Switch(config-if)# shutdown
Switch(config-if)# atm ilmi-enable
Switch(config-if)# no shutdown

To enable or disable ILMI connectivity procedures and to change the ILMI keepalive poll interval, use the atm ilmi-keepalive interface configuration command. To disable ILMI connectivity procedures, use the no form of this command.
atm ilmi-keepalive [T]
T | The period in seconds at which the IME is polled. The minimum is 3 seconds. |
Disabled
Interface configuration
This command does not apply to the ASP 2/0/0 interface.
This command enables ILMI connectivity procedures, as described in Section 8.3.1 of the ATM Forum ILMI 4.0 Specification.
The following example enables ILMI keepalives on ATM interface 1/0/0 with a poll interval set for 6 seconds.
Switch(config)# interface atm 1/0/0
Switch(config-if)# atm ilmi-keepalive 6
atm ilmi-enable

To configure the LECS address advertised by the switch to the end system, use the atm lecs-address interface configuration command.
atm lecs-address lecsaddress [sequence #]
lecsaddress | Address of the LAN Emulation configuration server. |
sequence # | Sequence number of the LECS. |
If the LECS address is not configured on an interface, the LECS address that was configured using the atm-lecs-address-default global configuration command is used by default.
Interface configuration
The LECS address is provided by the switch to directly connect LANE clients over the ILMI. LECS addresses can be configured on both interface and global levels. The globally configured address is sent to a port only if there is no LECS address configured on that port. The sequence number provides the position of this address in the ordered LECS address table.
atm lecs-address-default
show atm ilmi-configuration
To configure the LECS address advertised by the switch to the end system, use the atm lecs-address-default global configuration command.
atm lecs-address-default lecsaddress [sequence #]
lecsaddress | Address of the LAN Emulation configuration server. |
sequence # | Sequence number of the LECS. |
None
Global configuration
The LECS address is provided by the switch to directly connected LANE clients over the ILMI. LECS addresses can be configured on both interface and global levels. The globally configured address is sent to a port only if there is no LECS address configured on that port. The sequence number provides the position of this address in the ordered LECS address table.

To alter the propagation delay component of the cell-transfer delay offered by an interface, use the atm link-distance command. To reset the propagation delay to the default value, use the no form of this command.
atm link-distance p-value
p-value | Specified in units of kilometers (which is then divided by the speed of light in kps to derive a propagation delay in microseconds (0-65535)). |
Value is 0
Interface configuration
The cell-transfer delay is used for the resource connection admission control of a CBR or VBR-RT connection.
This resource management command is supported for interface and subinterface configurations and when interface metrics are provided to PNNI routing.
To create and delete well-known (reserved) PVCs with non-default connection identifiers or other non-default parameters, use the atm manual-well-known-vc interface configuration command. To reenable the automatic default well-known VC mode, use the no form of this command.
atm manual-well-known-vc [delete | keep]
delete | When specified, the existing, automatically created, VCs are deleted. If well-known VCs exist, you are prompted to confirm that the VC can be automatically deleted. If you reply no, then the command stops abruptly. |
keep | When specified, the existing, automatically created, well-known VCs remain in place and appear in the running configuration. |
no
Interface configuration
This command does not apply to the ASP interface (ATM 2/0/0).
All interfaces default to the no form of this command during initial start-up. The keep option becomes the default, on existing automatically created VCs, when manual mode is entered.
When this command is in effect, well-known VCs are not automatically created at startup. When this mode is enabled on an interface, the allowed range for VCI values are 5 through 16383, instead of 32 through 16383.
The three additional reserved channel encapsulation types added for the CPU PVCs are QSAAL, PNNI, and ILMI. These specify that the interface is a Signaling, PNNI, or ILMI reserved channel.
You must enter the copy running-config startup-config command to disable the automatic creation of default well-known VCs at system startup.
Although the OAM channels for tunnels are well-known channels (VCI 3 and VCI 4), they are not affected by the atm manual-well-known-vc status.
When using the no form of this command, if there are existing non-default reserved channel VCs for this interface, you are prompted to confirm that the VC can be automatically deleted. (If you enter no, the command stops abruptly.) Well-known VCs with default configurations are then automatically created for the interface. The default well-known PVCs are no longer shown as part of the running-configuration.
The following example puts an interface into the manual well-known-vc modes, deletes the existing default Signaling PVC, and then creates a Signaling PVC using a VCI value of 7.
Switch(config-if)# atm manual-well-known-vc keep
Switch(config-if)# no atm pvc 0 5

To enable point-to-multipoint signaling to the ATM switch ASP interface, use the atm multipoint-signaling interface configuration command. To disable point-to-multipoint signaling to the ATM switch, use the no form of this command.
atm multipoint-signalingThis command has no keywords and arguments.
Interface configuration
Interface configuration
This command only applies to the ASP and IP interface. If multipoint signaling is enabled, the switch uses existing static map entries that have the broadcast keyword set to establish multipoint calls. One call is established for each logical subnet of each protocol.
All destinations are added to the call. One multicast packet is sent to the ATM switch for each multipoint call. The ATM switch replicates the packet to all destinations.
To configure an ATM Network Network Interface (NNI) on the specified physical or logical (VP tunnel) port, use the atm nni interface configuration command.
atm nniThis command has no keywords or arguments.
Interface configuration
Before using this command the interface must be administratively shut down (see the shutdown command) and ILMI auto-configuration mode must be disabled (see the atm auto-configuration command).
The PNNI routing and signaling protocol is run over all NNI interfaces, except those interfaces on which signaling was previously disabled (see the atm signalling-enable command). To configure an IISP interface, use the atm iisp command.
The atm auto-configuration, atm iisp, atm nni, and atm uni commands are mutually exclusive. Configuring atm nni command overwrites any previous configuration of the atm iisp or atm uni commands for this interface. Future configuration of the atm auto-configuration, atm iisp, or atm uni command on this interface overwrites the atm nni command.
Configure an ATM NNI on logical port card 4, subcard 1, and port 3, and the VPI is 99.

To configure the NSAP-format ATM end-system address of an ATM interface, use the atm nsap-address interface configuration command. The no form of this command removes any configured address for the interface.
atm nsap-address nsap-address
nsap-address | The 40-digit hexadecimal NSAP address of this interface (the source address). |
No NSAP address is defined for this interface.
Interface configuration
This command only applies to the ASP interface and subinterfaces.
The NSAP-format ATM end system address of an interface is used by static maps (see the section "SVC Based Map-List Configuration" in the LightStream 1010 ATM Switch Software Configuration Guide) and by Classical IP over ATM, as defined in RFC 1577 (see the section "Configure Classical IP over ATM in a SVC Environment" in the LightStream 1010 ATM Switch Software Configuration Guide).
The NSAP-format ATM end system address of an interface can be configured using either the atm esi-address or the atm nsap-address command. Configuring a new address on the interface overwrites the previous address. The atm esi-address and atm nsap-address commands are mutually exclusive. Configuring the switch with the atm esi-address command negates the atm nsap-address setting, and vice versa.
NSAP-format ATM end system addresses have a fixed length of 40 hexadecimal digits. It is recommended that the address be configured using the following dotted format:
xx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.xx
The dots may be omitted.
The following example shows configuration of the NSAP-format ATM end system address for interface ATM2/0/0.1.
Switch(config)# interface atm 2/0/0.1
Switch(config-subif)# atm nsap-address 47.0091.8100.0000.1111.1111.1111.1111.1111.1111.00

To define an ATM map statement for an SVC, use the atm-nsap map-list configuration subcommand in conjunction with the map-list global configuration subcommand. The no form of this command removes the address.
protocol protocol-address atm-nsap atm-nsap-address [class class-name] [broadcast]
protocol | Specified as the keyword ip. |
protocol-address | Destination address that is being mapped to this SVC. |
atm-nsap-address | Destination ATM NSAP address. Must be exactly 40 hexadecimal digits long and in the correct dotted format. |
class class-name | (Optional) Name of a table that contains encapsulation-specific parameters. Such a table can be shared between maps that have the same encapsulation. |
broadcast | (Optional) Indicates this map entry is to be used when the corresponding protocol sends broadcast packets to the interface. |
aal5mux | (Optional) Uses aal5mux encapsulation. The default is snap. |
No map statements are defined.
Map-list configuration
This command is required with the map-list command when you are configuring an SVC.
In the following example, a map list named atmsvc includes one map statement for a destination address being mapped.
Switch(config)# map-list atm 1/0/0

To change the output queue maximum queue size, use the atm output-queue interface configuration command. To reset the maximum queue size to the default value, use the no form of this command.
atm output-queue [force] {cbr | vbr-rt | vbr-nrt | abr-ubr} max-size size-num
size-num | Queue size in cells, 256 to 65250. For installation in hardware, the number provided is rounded up to the next value available in the hardware. The configured and installed values are both displayed using the show atm interface command. |
max-size | Maximum output queue size per service category. |
Varies by physical interface type, queue, and for abr-ubr or vbr-nrt queues, by the value of Over Subscription Factor (OSF).
Interface configuration
The force argument indicates that the change should be made even if it results in losing data on the interface queue (the queue must be momentarily disabled to change the threshold). This command without the force argument only changes the threshold if the interface is down. An error message is displayed and the command does not take effect if the interface is up and the force argument is not present.
This command is not supported for the subinterface configuration and does not apply to the ASP 2/0/0 interface.
You can configure the parameters only on physical ports 0 or 6 on a 25-Mbps PAM.
In the following example, the maximum size of the vbr-nrt output queue is set to a minimum of 512 cells. This can be set even if the interface is up.
Switch(config-if)# atm output-queue force vbr-nrt max-size 512

To change the output queue thresholds, use the atm output-threshold interface configuration command. To reset the threshold to the default value, use the no form of this command.
atm output-threshold {cbr | vbr-rt | vbr-nrt | abr | ubr} discard disc-thresh-num
disc-thresh-num | Number 12, 25, 37, 50, 62, 75, 87, or 100 indicating the percentage of queue-full. Using 100 disables the threshold. |
efci-thresh-num | Number 12, 25, 50, or 100, indicating the percentage of queue-full using 100 disables the threshold. |
abr-thresh-num | Number 12, 25, 37, 50, 62, 75, 87, or 100 indicating the percentage of queue-full. Using 100 disables the threshold. |
efci | When cells arrive on connections to a congested (as indicated by efci threshold) output queue on the interface, the efci bit in the cell header is set. |
relative-rate | When a backward RM-cell is received on an ABR connection on the interface (from outside the switch), its congestion-bit is set if the interface abr-ubr output-queue is congested (as indicated by the abr relative-rate threshold). |
discard | When a cell arrives at a congested output queue (as indicated by discard-threshold), it is eligible for clp discard (or EPD if EPD is enabled on the connection). |
For all service categories discard is 87 percent and efci is 25 percent. The abr relative-rate is 25 percent.
Interface configuration
This command is not supported for subinterface configuration. This command does not apply to the ASP 2/0/0 interface.
You can configure the ABR parameter relative-rate only on physical ports 0 or 6 on a 25-Mbps PAM.
In the following example, the discard threshold of the VBR-NRT queue is set to 87 percent of the maximum queue size.
Switch(config-if)# atm output-threshold vbr-nrt discard 87
To set the OSF use, the atm over-subscription-factor global configuration command. To assign the default value to OSF, use the no form of this command.
atm over-subscription-factor o-value
o-value | A positive integer from 1 to 32. |
Value is 8
Global configuration
The OSF number is a positive integer in the range from 1 through 32. This command is used to determine the initial port queue size. OSF is used to size the vbr-nrt and abr-ubr queues.
The resizing of queues can be overridden by using the atm output-queue command. Changes to atm over-subscription-factor only take place during start-up.
The sizing of vbr-nrt and abr-ubr queues is determined by the following equations.
size (vbr-nrt) = .25 * ((osf * 2048) - DefaultSize (cbr) - DefaultSize (vbr-rt)) size (abr-ubr) = .75 * ((osf * 2048) - DefaultSize (cbr) - DefaultSize (vbr-rt))
The default size of the cbr and vbr queues vary by interface type as defined in the following list:
| Interface Type | Default Max Size CBR Queue | Default Max Size VBR-RT Queue |
|---|---|---|
SONET | 256 | 256 |
DS3/E3 | 256 | 512 |
In the following example, the over-subscription-factor of the switch is set to 15. This does not take effect in resizing ubr and vbr-nrt queues unless the configuration is written to NVRAM and the switch is restarted.
Switch(config)# atm over-subscription-factor 15

To enable or change the artificial limitation on interface output rate, use the atm pacing interface configuration command. To disable output pacing, use the no form of this command.
atm pacing r-value [force]
r-value | Bit rate in thousand bits per second (kbps). |
No pacing
Interface configuration
The force argument indicates that the change should be made even if it results in an output cell-rate that does not provide sufficient bandwidth for guaranteed service on the transmit flow of the interface. An error message is displayed and the command does not take effect if the change impacts guaranteed bandwidth and the force argument is not present.
This command is not supported for subinterface configuration and does not apply to the ASP 2/0/0 interface. You cannot configure this parameter on OC-12 and 25-Mbps ports.
In the following example, the transmit cell-rate of the interface is limited to the closest value possible in hardware, greater than 30,000 kbps. If the amount of bandwidth allocated to cbr and vbr connections in the transmit direction on the interface is greater than 30,000 kbps, the command fails.
Switch(config-if)# atm pacing 30000
To specify the administrative weight of the ATM PNNI interface, use the atm pnni admin-weight interface configuration command. To return to the default values, use the no form of this command.
atm pnni admin-weight number service-category
number | The administrative weight value assigned to the interface (1 to 1000000). Refer to the administrative-weight command for default values. |
service-category | The keywords are cbr, vbr-rt, vbr-nrt, abr, ubr, or all. |
Determined by the mode set by administrative-weight command.
Interface configuration
This command does not apply to the ASP 2/0/0 interface and applies only the NNI interface.
Use this command to manually set the administrative weight of an interface. Changing the administrative weight of an interface to a larger value might cause calls to be routed away from the interface.

show atm pnni interface
To configure a method for selecting a link out to multiple links to the same neighbor, use the atm pnni link-selection interface configuration command. To return to the default value, use the no form of this command.
atm pnni link-selection [admin-weight-minimize | blocking-minimize | load-balance |
admin-weight-minimize | Transmits call on the interface with the lowest administrative weight. |
blocking-minimize | Minimizes subsequent call blocking. |
load-balance | Balances calls across parallel links. |
transmit-speed-maximize | Transmits calls on highest speed parallel link. |
blocking-minimize
Interface configuration
This command does not apply to the ASP 2/0/0 interface.
This command only affects CBR and VBR calls. Load balancing is always used for ABR and UBR calls.
Link selection applies whenever the port specified in the Designated Transit List (DTL) is zero and there are multiple interfaces to the next node.
When multiple parallel links are configured inconsistently, the order of precedence of configured values is admin-weight-minimize, blocking-minimize, transmit-speed-maximize, and load-balance. For example, if any link is configured as admin-weight-minimize, that becomes the link selection criteria for the entire group.
To specify which PNNI node in the switch runs on an interface when the interface runs PNNI, use the atm pnni node interface configuration command. To return to the default value, use the no form of this command.
atm pnni node node-index
node-index | An integer, from 1 through 255, identifying a PNNI node running on this switch. Currently only a single lowest-level node with node index 1 is supported. |
Node index 1
Interface configuration
This command does not apply to the ASP 2/0/0 interface.
Currently node index 1 is the only valid value. Refer to the node command for more information.
By default, PNNI node 1 automatically runs on all PNNI interfaces.
This command does not turn PNNI on or off for this interface. See the atm auto-configuration command and the atm nni commands for more information on the interface type.

To configure an ILMI address prefix for an ATM interface, use the atm prefix interface configuration command. To delete a configured ILMI address prefix, use the no form of this command.
atm prefix 13-byte_prefix
13-byte_prefix | A 13-byte ATM address prefix, specified as 26 hexadecimal digits. |
Interface configuration
This command is used to assign one or more address prefixes to a specific interface that is different from any prefixes based on the switch addresses (see the atm address command). ILMI assigns the prefix to end systems attached to this interface. These prefixes are used as network prefixes during ILMI address registration.
Whenever one or more ILMI address prefix is assigned on an interface, no network prefixes derived from the switch address are used for address registration on that interface.
The following example shows how to configure an ILMI address prefix on interface ATM 3/1/0.
Switch(config)# interface atm 3/1/0

Wildcard character ellipses (...) after a prefix means to "match any destination address that starts with the prefix." |
card/subcard/port | Identified the card, subcard, and port number for the ATM interface. |
.vpt# | Specifies an interface that represents a virtual path tunnel. |
internal | Specifies an internal static route to an internal reachable address prefix. By default, an exterior static route to an exterior reachable address prefix is created. |
scope org-scope | Specifies the organizational scope (for example, UNI scope) value for the route. The valid range of organizational scope values is from local (1) to global (15). The default organizational scope is global (15) for individual addresses and local (1) for group addresses. |
e164-address | Associates a forwarding E.164 address with the static route. |
address_string | Specifies a forwarding native E.164 address, used when a call matching the ATM address prefix is forwarded across the specified interface. The E.164 address consists of 7 to 15 decimal characters. |
number type | Specifies a number from the following four options: international, national, subscriber and local. |
See individual commands.
Global configuration
The internal keyword should be used when a static route is configured to an address prefix representing an attached end system (for example, in place of an ILMI address registration).
The type of static route should be exterior, and the internal keyword should not be present when a static route is configured to an address prefix representing end systems attached to a different switch or network.
The scope keyword value translates to a PNNI level according to the PNNI scope map. Refer to the scope-map and scope-mode commands for more information.
When the e164-address option is included, the specified address_string is passed on as the called party address. The received called party address is passed on as the called party subaddress, the E.164 address of this interface (configured using the atm e164-address command) is passed on as the calling party address, and the received calling party address (if any) is passed on as the calling party subaddress.
If no e164-address is specified, the received called party address and calling party address are passed on unchanged.
The following example shows how to configure a static route on interface ATM 1/2/1 to the address prefix 47.8 of 12 bits in length.
Switch(config)# atm route 47.8... atm 1/2/1
The following example shows how to configure a static route on interface ATM 1/2/1 to the address prefix 47.88 of 14 bits in length.
Switch(config)# atm route 47.8(10*)... atm 1/2/1

To enable route optimization on an ATM interface, use the atm route-optimization interface configuration command. To disable this feature, use the no form of this command.
atm route-optimization soft-connection [interval interval] [time-of-day {anytime | start-time end-time}]
interval | Specifies the frequency of route optimization in minutes. The range is 10 to 10000. The default is 60 minutes. |
soft-connection | Specifies that route optimization is enabled for all soft PVCs and soft PVPs for which this is the source interface. |
time-of-day | Specifies the time range during which route optimization can occur. |
anytime | Represents a 24-hour time range. The default time-of-day is anytime. |
start-time | Specifies the start of the time range during which route optimization is allowed, in 24-hour format, hh:mm. |
end-time | Specifies the end of the time range during which route optimization is allowed, in 24-hour format, hh:mm. |
See individual keywords.
Interface configuration
The time-of-day is used as a filter to determine whether route optimization is acceptable when the interval timer activates.
To ensure that route optimization takes place at least once a day, set the interval to a smaller value than the time range. Once route-optimization starts, it runs until it is finished regardless of the time range. All connections on this interface that are subject to route optimization are checked to see if better paths exist. When better paths are found, the connections are rerouted (see the atm route-optimization percentage-threshold command).
The following example enables soft VC route optimization on interface ATM 0/1/2, with the time period of 120 minutes.
Switch(config)# interface atm 0/1/2
Switch(config-if)# atm route-optimization soft-connection interval 120
atm route-optimization (EXEC Command)

show atm interface
To immediately initiate route optimization for a specific interface or specific soft-vc, use the atm route-optimization EXEC command.
atm route-optimization soft-connection interface atm card/subcard/port [vpi [vci]]
card/subcard/port | Card number, subcard number, and port number of a specific ATM interface. |
vpi | Virtual Path Identifier. |
vci | Virtual Channel Identifier. |
EXEC
If vpi and vci are not specified, this command sets optimization for a specific interface. If vpi and vci are specified, this command sets optimization for a specific soft-vc.
atm route-optimization (Interface Configuration Command)
atm route-optimization percentage-threshold
To specify the percentage reduction in the administrative weight of the existing path required to trigger route optimization, use the atm route-optimization percentage-threshold global configuration command. To set the threshold to the default value, use the no form of this command.
atm route-optimization percentage-threshold percent
percent | Specify the route-optimization threshold in percent from 5 to 100. |
30
Global configuration
When route optimization is enabled and the threshold is exceeded, the existing path is partially torn down and a new path is established. Currently route optimization is only supported for soft PVCs and soft PVPs.
Smaller values lead to greater network efficiency, at the expense of an increased amount of calls subject to rerouting.
The following example shows setting the route-optimization threshold to 20 percent.
Switch(config)# atm route-optimization percentage-threshold 20
atm route-optimization (Interface Configuration Command)

To start the PNNI configuration mode, use the atm router pnni global configuration command.
atm router pnniThis command has no arguments or keywords.
Global configuration
Use this command to start global PNNI configuration mode.
The following example shows using the atm router pnni global configuration command to change to ATM router PNNI configuration mode.
Switch(config)# atm router pnni
Switch(config-atm-router)#
To restrict the mode of ATM routing on an ATM switch, use the atm routing-mode global configuration command. To remove all restrictions on ATM routing, use the no form of this command.
atm routing-mode static
static | Restricts ATM routing to allow only static configuration of ATM routes. In this routing mode, the switch does not run any dynamic ATM routing protocols, such as PNNI routing. |
Disabled (no restrictions on ATM routing)
Global
This command takes effect on the next reboot.
Switch behavior in static routing mode is analogous to that of the LS1010 default IISP software images of Release 11.1. Without any restrictions on the routing mode, PNNI functionality is available on all interfaces.
This command differs from deletion of all PNNI nodes (using the node command) because it affects ILMI auto-configuration. When the switch is in static routing mode, for each interface, this switch's ILMI variable atmfAtmLayerNniSigVersion is set to iisp. This causes ILMI auto-configuration on interfaces between two switches to determine an interface type of IISP, unless the switch on the other side indicates NNI signaling protocol is not supported.
The following example shows configuration of a switch to allow only static routing.
Switch(config)# atm routing-mode static
To set the limits on the number of cells simultaneously allowed in the switch memory by type of output queue, use the atm service-category-limit global configuration command. To set to the default value of 65,535, use the no form of this command.
atm service-category-limit {cbr | vbr-rt | vbr-nrt | abr-ubr} l-value
l-value | Integer in the range from 0 through 65,535, specified in units of cells. |
65535
Global configuration
The no form of this command applies to all service categories.
 | Warning Setting a service-category-limit to 0 causes the connection requests for the associated service categories to be rejected. |
In the following example, the maximum number of abr and ubr cells allowed into the switch-fabric at one time is limited to 45,000.
Switch(config)# atm service-category-limit abr-ubr 45000
To enable the signaling/sscop on a port, use the atm signalling-enable interface configuration command. To disable the signaling/sscop, use the no form of this command.
atm signalling-enableThis command has no arguments or keywords.
Enabled
Interface configuration
When this command is used on physical or logical ports, the interface must be administratively shut down. This command, when used to disable signaling on a PNNI interface, disables PNNI routing as well as PNNI signaling.
This command does not apply to the ASP interface.
The following example disables signaling on ATM 0/1/2.
Switch(config)# interface atm 0/1/2
Switch(config-if)# shutdown
Switch(config-if)# no atm signalling-enable
Switch(config-if)# no shutdown
To set the current port snooping configuration and actual register values for the highest ATM interface, use the atm snoop interface atm interface configuration command.
atm snoop interface atm monitored_port [direction dir]
monitored_port | Card, subcard, and port number for the ATM interface to be monitored. The port can be any port except the ASP 2/0/0 port or the test port itself. |
dir | Is specified as receive or transmit and determines the direction of the cell traffic to monitor. The default is receive. |
Receive
Interface configuration. Applies to the Snoop Test Port.
The atm snoop interface atm subcommand applies only if the previously specified port is the highest system port residing on card 4 and subcard 1 (which has been shutdown). If so, this enables it as the Snoop Test Port. Cells transmitted from the Snoop Test Port are copies of cells from a single direction of a monitored port.
When in snoop mode, any prior permanent virtual connections to the Snoop Test Port remain in the down state.
The port number of the test port depends on the card type. Table 2-4 defines the Snoop Test Port number for various interfaces:
| Interface | Port Number |
|---|---|
oc3 | 4/1/3 |
oc12 | 4/1/0 |
ds3/e3 | Not supported |
The following example configures the highest port in the snoop mode to monitor port card 1, subcard 0, and port 2 in the transmit direction starting from the configuration mode.
Switch(config)# interface atm 4/1/3
Switch(config-if)# shutdown
Switch(config-if)# atm snoop interface atm 1/0/2 direction transmit
Switch(config-if)# no shutdown
To create a soft PVC on the switch, use the atm soft-vc interface configuration command.

To change the Sustained Cell Rate Margin Factor (SCRMF), use the atm sustained-cell-rate-margin-factor global configuration command. SCRMF dictates the weight given to peak-cell-rate (PCR) in computing the bandwidth used by VBR connections. To assign the default value to SCRMF, use the no form of this command.
atm sustained-cell-rate-margin-factor s-value
s-value | Percent value that dictates the weighting of PCR with respect to sustained-cell-rate (SCR) in computing the bandwidth used in CAC of VBR connections. |
1 percent
Global configuration
The following equation is used in CAC of VBR connections to define the bandwidth requested.
bandwidth = (SCRMF * (PCR-SCR))/100 + SCR
In the following example, the SCRMF of the switch is set to 35 percent.
Switch(config)# atm sustained-cell-rate-margin-factor 35
To install frame discard and to select the criteria used on SVCs, use the atm svc-frame-discard-on-aal5ie command.
atm svc-frame-discard-on-aal5ieThis command has no arguments or keywords.
Install packet discard based on the presence of the AAL5 IE in the SETUP message.
Global configuration
The common term "frame discard" is referred to as "packet discard" in the LS1010 VC environment.
This command changes information used by the switch when determining whether or not to install frame discard on SVCs. UNI 4.0 signaling allows explicit signaling of frame discard. Prior to UNI 4.0, the presence of the AAL5 IE was used to determine whether or not to install frame discard. If the AAL5 IE is present, frame discard is installed.
Use the atm svc-frame-discard-on-aal5ie command to install frame discard if the AAL5 IE is present. Use the no atm svc-frame-discard-on-aal5ie command if frame discard is to be installed on UNI 4 or PNNI interfaces, and only if explicitly requested by the SETUP and CONNECT messages.
The installation of frame discard is controlled by the signalled messages. Even if the configuration specifies using AAL5 IE, if the UNI 4.0 signaling element controlling frame discard is present when the SETUP or CONNECT transits a UNI 4 or PNNI interface, and the AAL5 IE is not present, frame discard is controlled by the TM Options ID.
The signaling element is the Traffic Management Options ID in the ATM Traffic Descriptor Information Element in the SETUP or CONNECT message.
In the following example, the switch behavior is set to not use the AAL5 IE to dictate frame discard.
Switch(config)# no atm svc-frame-discard-on-aal5ie
To change the intended Usage Parameter Control (UPC) mode to use on the cell-flow received into the switch-fabric for SVCs on an interface, use the atm svc-upc-intent interface configuration command. Any change in this parameter is applied to SVCs subsequently established on the interface. To assign the default value to the parameter, use the no form of this command.
atm svc-upc-intent [pass | tag | drop]
pass | Cells received on the interface are passed to the switching fabric with no change, regardless of their conformance to the traffic contract. |
tag | Cells received on the interface violating the traffic contract have their CLP bit set prior to entering the switching fabric. |
drop | Cells received on the interface violating the traffic contract are dropped. |
Interface configuration
pass
This configuration parameter determines the UPC to use for SVCs and for the destination leg of soft VC and VP. If policing is desired, it should be applied once for traffic entering a network.
This command does not apply to the ASP 2/0/0 interface or logical interfaces.
In the following example, the intended UPC for SVCs on an interface is set to tagging.
Switch(config-if)# atm svc-upc-intent tag
To configure an ATM address template alias, use the atm template-alias global configuration command. To delete the specified alias, use the no form of this command.
atm template-alias name template
name | Name for the template alias. |
template | ATM address template, which can be a single ATM address that matches itself or that contains wildcards and/or prefixes or suffixes, allowing a single template to match many addresses. The symbols used for wildcards, prefixes, and suffixes are as follows: · Asterisk (*) to match any single 4-bit nibble in the address. · Ellipsis (...) to match any number of leading or trailing 8-bit hexadecimal digits in the address. · Asterisk (*) to match any single binary digit in a 4-bit nibble in the address, where the 4 binary bits are enclosed within parentheses. |
No alias list is defined.
Global configuration
Address templates are pattern forms that match one or more ATM addresses. They can be simple, single ATM addresses matching themselves or containing wildcards, prefixes, and suffixes, allowing a single template to match many addresses.
The simplest address template matches a single address, as shown in this example:
Switch(config)# 47.0005.1234.5678.9abc.def0.00
Wildcard digits, which can match any value, are indicated with asterisks (*). The following template matches the above address and any other 12-byte address that starts with 47.0005.1234.5678:
Switch(config)# 47.0005.1234.5678.****.****.**
The following template matches any address of any length and begins with the prefix 47.0005.1234.5678:
Switch(config)# 47.0005.1234.5678...
In other cases, matching a suffix of the address is also important, such as when matching system IDs. The following template matches any address ending with the suffix 0000.0c01.2345.00:
Switch(config)# ...0000.0c01.2345.00
You might want to match addresses on a single-bit granularity, rather than half-byte (4-bit or nibble) granularity.
This pattern matching is supported by allowing the hex digits that represent four bits to be replaced by groups of four binary bits, represented by the numbers 0 and 1. These four binary digits are enclosed within parentheses. The following template matches any address that starts with 47.0005 followed by the binary bits 10. The final two binary bits in the nibble can be either 0 or 1 and are represented with asterisks.
Switch(config)# 47.0005.(10**)...
Use this command to define aliases for commonly referenced address templates. The use of these aliases reduces the chances for typographical error in the creation of ATM filter sets.
The following example shows setting ATM template aliases.
Switch(config)# atm template-alias atm_addr1 47.1328...
Switch(config)# atm template-alias atm_addr2 47.0012.(10**)...
Switch(config)# atm template-alias atm_addr3 ...1234.(01*1)

To configure an ATM User-Network Interface (UNI) on the specified physical or logical port, use the atm uni interface configuration command.
atm uni [side side] [version ver] [type type]
side | Specified as user | network. The default is network. |
ver | Specified as 3.0, 3.1, or 4.0 |
type | Specified as private | public. The default is private. |
See individual commands.
Interface configuration
Before using this command, the interface must be administratively shut down (see the shutdown command) and ILMI auto-configuration mode must be disabled (see the atm auto-configuration command).
The atm auto-configuration, atm iisp, atm nni, and atm uni commands are mutually exclusive. Configuring atm uni command overwrites any previous configuration of the atm iisp or atm nni commands for this interface. Future configuration of the atm auto-configuration, atm iisp, or atm uni command on this interface overwrites the atm uni command.
Configure a network-side private ATM UNI with maxvc = 1000, on card 3, subcard 1, and port 1.
Switch# interface atm 3/1/1
Switch(config-if)# shutdown
Switch(config-if)# no atm auto-configuration

To define an ATM map statement for a PVC, use the atm-vc map-list configuration command in conjunction with the map-list global configuration command. The no form of this command removes the address.
protocol protocol-address atm-vc vci [class class-name] [broadcast] [aal5mux]
protocol | Is the keyword ip. |
protocol-address | Destination address being mapped to this PVC. |
vci | 31 < vci < 2**14 - 1 (with default max-VCI bits that is 14). |
class class-name | (Optional) Name of a table that contains encapsulation-specific parameters. Such a table can be shared between maps that have the same encapsulation. |
broadcast | (Optional) Indicates this map entry is to be used when the corresponding protocol sends broadcast packets to the interface. |
aal5mux | (Optional) Use aal5mux encapsulation. Default is snap. |
No map statements are defined.
Map-list configuration
This command is required with the map-list command when you are configuring an SVC.
In the following example, a map list named ATM includes two map statements for protocol addresses being mapped.
Switch(config)# map-list atm 1/0/0
Switch(config-map-list)# map-list atm
