This chapter describes the ATM commands and command syntax that are unique to Cisco MC3810 series concentrators. ATM commands that do not differ from standard Cisco IOS software are not documented here. For information about standard ATM commands from Cisco IOS software, refer to the Wide-Area Networking Command Reference.
For ATM configuration information and examples, refer to the Wide-Area Networking Configuration Guide.
To specify the software compression mode on the Cisco MC3810, use the atm compression interface configuration command. Use the no form of this command to remove the compression mode setting.
atm compression {per-packet | per-interface | per-vc}
per-packet | Packet-by-packet compression mode (no history). This is the default. |
per-interface | One context per interface (with history). |
per-vc | One context for every virtual circuit (with history). |
Packet-by-packet compression is enabled.

11.3 MA | This command was first introduced. |
This command applies to ATM configuration on the Cisco MC3810.
The following example configures per-packet ATM compression for a Cisco MC3810 running Cisco IOS Release 11.3 MA:
interface serial2 atm compression per-packet
The following example configures per-packet ATM compression for a Cisco MC3810 running Cisco IOS Release 12.0 or later:
interface atm0 atm compression per-packet
| Command | Description |
Specifies compression for the voice connection on an ATM permanent virtual circuit (PVC). |
To create a PVC on an ATM interface and, optionally, to generate Operation, Administration, and Maintenance (OAM) F5 loopback cells or enable Inverse ATM Address Resolution Protocol (ARP), use the atm pvc interface configuration command. The no form of this command removes the specified PVC.
In Cisco IOS Releases prior to 12.0:
atm pvc vcd vpi vci aal-encap [peak average [burst]] [inarp [minutes]] [oam [seconds]]In Cisco IOS Releases 12.0 and later, this command is superseded by the atm command.
vcd | Virtual circuit descriptor. A unique number that identifies to the processor which VPI-VCI pair to use for a particular packet. Valid values range from 1 to the value set with the atm max vc command. The AIP or ATM port adapter requires this feature to manage packet transmission. The vcd value is not associated with the VPI-VCI pair used for the ATM network cells. The NPM has a hard-coded max vcd value of 1023. Valid values are 1 to 1023. |
vpi | ATM network virtual path identifier (VPI) of this PVC. The VPI is an 8-bit field in the header of the ATM cell. The VPI value is unique only on a single link, not throughout the ATM network, because it has local significance only. The VPI value must match that of the switch. Valid values are 0 to 255. The arguments vpi and vci cannot both be set to 0; if one is 0, the other cannot be 0. |
vci | ATM network virtual channel identifier (VCI) of this PVC, in the range of 0 to 1 less than the maximum value set for this interface by the atm per-vc per-vp command. Typically, lower values of 0 to 31 are reserved for specific traffic and should not be used (for example, F4 OAM, SVC signaling, ILMI, and so on). Valid values are 0 to 1023. The VCI is a 16-bit field in the header of the ATM cell. The VCI value is unique only on a single link, not throughout the ATM network, because it has local significance only. The arguments vpi and vci cannot both be set to 0; if one is 0, the other cannot be 0. |
aal-encap | ATM adaptation layer (AAL) and encapsulation type. Possible values are as follows: · aal5snap---Used for Logical Link Control/Subnetwork Access Protocol (LLC/SNAP) precedes the protocol datagram. This is the only encapsulation supported for Inverse ARP. · aal1---Used to encapsulate streaming video packets over ATM. · aal5fratm---Used for the Frame Relay-ATM interworking function. · aal5voice---Used for voice traffic over ATM. |
aal-encap (continued) | · aal5mux---Used for Multiplex-type virtual circuit. · aal5nlpid---Used for High-Speed Serial Interfaces (HSSIs) that are using an ATM data service unit (ADSU) and running ATM-Data Exchange Interface (DXI). · ilmi---Used to define the PVC for ILMI. |
peak | (Optional) Maximum rate (in kbps) at which this virtual circuit can transmit. The valid range is 56 to 10000. If configuring Voice over ATM, you must configure the peak, average and burst values. To calculate the peak rate for the number of voice calls, use the following calculation: (2 x the number of calls) x 16 |
average | (Optional) Average rate (in kbps) at which this virtual circuit transmits. Valid values are platform dependent. If configuring Voice over ATM, you must configure the peak, average and burst values. To calculate the average rate for the number of voice calls, use the following calculation: (1 x the number of calls) x 16 |
burst | (Optional) Value that relates to the maximum number of ATM cells the virtual circuit can transmit to the network at the peak rate of the PVC for bursty traffic. If configuring Voice over ATM, you must configure the peak, average and burst values. To calculate the burst rate for the number of voice calls, use the following calculation: 4 x the number of calls |
inarp minutes | (Optional) (Set for the aal5snap encapsulation only) Specifies how often Inverse ARP datagrams are sent on this virtual circuit. The valid range is 1 to 60. The default value is 15 minutes. |
oam seconds | (Optional) Specifies the time interval in seconds for generating OAM F5 loopback cells from this virtual circuit. The valid range is 1 to 600. The default value is 10. |
compress | (Optional) Enables payload compression. If compression hardware is present, then the compression method is hardware. If compression hardware is not present, software compression is used. This option is available only on the Cisco MC3810. |
If the oam keyword is omitted, OAM cells are not generated. If the oam keyword is present but the seconds value is omitted, the default value of oam seconds is 10 seconds.
If the inarp keyword is omitted, Inverse ARPs are not generated. If the inarp keyword is present, but the timeout value is not given, then Inverse ARPs are generated every 15 minutes.
If peak and average rate values are omitted, the PVC defaults to peak and average rates equal to the link rate. The peak and average rates are then equal. By default, the virtual circuit is configured to run as fast as possible.
Interface configuration
| Release | Modification |
|---|---|
10.0 | This command was first introduced. |
11.0 | The oam seconds and inarp minutes commands first appeared. |
12.0 | This command was replaced by the pvc command. |
The order of command options is important. The inarp keyword can be specified either separately or before the oam keyword has been enabled. The peak, average, and burst arguments, if specified, cannot be specified after either the inarp or the oam keywords.
The Cisco IOS software dynamically creates rate queues as necessary to satisfy the requests of atm pvc commands. The software dynamically creates a rate queue when an atm pvc command specifies a peak or average rate that does not match any user-configured rate queue.
The atm pvc command creates a PVC and attaches it to the VPI and VCI specified. The arguments vpi and vci cannot both be specified as 0; if one is 0, the other cannot be 0. The aal-encap argument determines the AAL mode and the encapsulation method used. The peak and average arguments determine the rate queue used.
If you choose to specify peak or average values, you must specify both.
The router generates and echoes OAM F5 loopback cells, which verify connectivity. If OAM cell generation is enabled, a cell is transmitted periodically. The remote end must respond by echoing back the cells.
The router does not generate alarm indication signal (AIS) cells, which are used for alarm surveillance functions. However, if it receives an AIS cell, it responds by sending an OAM far-end remote failure (FERF) cell.
The following example configures a PVC with a VCD of 1, a VPI of 100, and a VCI of 100, for VoATM capable of handling 12 calls, with an OAM F5 loopback cell generated every 10 seconds, and payload compression enabled, for a Cisco MC3810 running Cisco IOS Release 11.3 MA:

| Release | Modification |
|---|---|
11.3 T | This command was first introduced. |
12.0 | This command superseded the encapsulation atm command for the Cisco MC3810, and the aal5mux frame and aal5mux voice suboptions appeared. |
Use one of the aal5mux encapsulation options to dedicate the specified PVC to a single protocol; use the aal5snap encapsulation option to multiplex two or more protocols over the same PVC. Whether you select aal5mux or aal5snap encapsulation might depend on practical considerations, such as the type of network and the pricing offered by the network. If the network's pricing depends on the number of PVCs set up, aal5snap might be the appropriate choice. If pricing depends on the number of bytes transmitted, aal5mux might be the appropriate choice because it has slightly less overhead.
If you specify virtual template parameters after the ATM PVC is configured, you should issue a shutdown command followed by a no shutdown command on the ATM subinterface to restart the interface, causing the newly configured parameters (such as an IP address) to take effect.
The following example configures a PVC to support encapsulation for Voice over ATM on the Cisco MC3810:
pvc 20 encapsulation aal5mux voice
The following example configures a PVC to support encapsulation for Frame Relay-ATM Interworking on the Cisco MC3810:

Use the pvc interface configuration command to do one or more of the following:
To remove an ATM PVC, use the no form of this command.
pvc [name] vpi/vci [ilmi | qsaal | smds]
name | (Optional) The name of the PVC or map. The name can be up to 16 characters long. |
vpi/ | ATM network virtual path identifier (VPI) for this PVC. The absence of the "/" and a vpi value defaults the vpi value to 0. On the Cisco MC3810 series concentrators, this value ranges from 0 to 255. The arguments vpi and vci cannot both be set to 0; if one is 0, the other cannot be 0. |
vci | ATM network virtual channel identifier (VCI) for this PVC. This value ranges from 0 to 1 less than the maximum value set for this interface by the atm vc-per-vp command. Typically, lower values 0 to 31 are reserved for specific traffic (for example, F4 OAM, SVC signaling, ILMI, and so on) and should not be used. The VCI is a 16-bit field in the header of the ATM cell. The VCI value is unique only on a single link, not throughout the ATM network, because it has local significance only. The arguments vpi and vci cannot both be set to 0; if one is 0, the other cannot be 0. |
ilmi | (Optional) Used to set up communication with the ILMI; the associated vpi and vci values are ordinarily 0 and 16, respectively. |
qsaal | (Optional) A signaling-type PVC used for setting up or tearing down SVCs; the associated vpi and vci values are ordinarily 0 and 5, respectively. |
smds | (Optional) Encapsulation for SMDS networks. If you are configuring an ATM PVC on the ATM Interface Processor (AIP), you must configure AAL3/4SMDS using the atm aal aal3/4 command before specifying smds encapsulation. If you are configuring an ATM network processor module (NPM), the atm aal aal3/4 command is not required. SMDS encapsulation is not supported on the ATM port adapter. |
No PVC is defined. When a PVC is defined, the global default of the encapsulation command applies (aal-encap = aal5snap).

11.3 T | This command was first introduced. |
12.0 | This command superseded the atm pvc command. |
The Cisco IOS software dynamically creates rate queues as necessary to satisfy the requests of the pvc commands.
The pvc command creates a PVC and attaches it to the VPI and VCI specified. The vpi and vci arguments cannot both be simultaneously specified as 0; if one is 0, the other cannot be 0.
When configuring an SVC, use the pvc command to configure the PVC that handles SVC call setup and termination. In this case, specify the qsaal keyword. See the second example that follows.
Once you specify a name for a PVC, you can reenter the interface-ATM-VC configuration mode by simply entering pvc name. You can remove a PVC and any associated parameters by entering no pvc name or no pvc vpi/vci.
If ilmi, qsaal, or smds encapsulation is not explicitly configured on the ATM PVC, the PVC inherits the following default configuration (listed in order of precedence):
The following example creates a PVC with VPI 0 and VCI 16, and communication is set up with the ILMI:
pvc cisco 0/16 ilmi exit
The following example creates a PVC used for ATM signaling for an SVC. It specifies VPI 0 and VCI 5:

This command applies to Voice over ATM on the Cisco MC3810.
The vbr-rt command configures traffic shaping between voice and data PVCs. Traffic shaping is required so that the carrier does not discard calls. To configure voice and data traffic shaping, you must configure the peak, average, and burst options for voice traffic. Configure the burst value if the PVC will be carrying bursty traffic. The peak, average, and burst values are needed so the PVC can effectively handle the bandwidth for the number of voice calls. To calculate the minimum peak, average, and burst values for the number of voice calls, use the following calculations:
The following example configures the traffic shaping rate for ATM PVC 20 on a Cisco MC3810. In the example, the peak, average and burst rates are calculated based on a maximum of 20 calls on the PVC.
