To enable end-to-end F5 OAM loopback cell generation and OAM management for an ATM PVC or VC class, use the oam-pvc command in the appropriate command mode. Use the no form of this command to disable generation of OAM loopback cells and OAM management.
oam-pvc [manage] [frequency]
manage | (Optional) Enable OAM management. |
frequency | (Optional) Number of seconds between transmitting OAM loopback cells. Values range from 0 to 600 seconds. Default is 10 seconds. |
End-to-end F5 OAM loopback cell generation and OAM management are disabled, but if OAM cells are received, they are looped back. The default value for the frequency is 10 seconds.
Interface-ATM-VC configuration (for an ATM PVC)
VC-class configuration (for a VC class)
This command first appeared in Cisco IOS Release 11.3 T.
If OAM management is enabled, further control of OAM management is configured using the oam retry command.
If the oam-pvc command is not explicitly configured on an ATM PVC, the PVC inherits the following default configuration (listed in order of next highest precedence):
The following example enables end-to-end F5 OAM loopback cell transmission and OAM management on an ATM PVC with a transmission frequency of 3 seconds:
oam-pvc manage 3

ilmi manage
oam retry
To configure parameters related to OAM management for an ATM PVC, SVC, or VC class, use the oam retry command in the appropriate command mode. Use the no form of this command to remove OAM management parameters.
oam retry up-count down-count retry-frequency
up-count | Number of consecutive end-to-end F5 OAM loopback cell responses that must be received in order to change a PVC connection state to up. This argument does not apply to SVCs. |
down-count | Number of consecutive end-to-end F5 OAM loopback cell responses that are not received in order to change a PVC state to down or tear down an SVC connection. |
retry-frequency | The frequency (in seconds) that end-to-end F5 OAM loopback cells are transmitted when a change in UP/DOWN state of a PVC or SVC is being verified. For example, if a PVC is up and a loopback cell response is not received after the frequency (in seconds) specified using the oam-pvc command, then loopback cells are sent at the retry-frequency to verify whether or not the PVC is down. |
up-count = 3, down-count = 5, retry-frequency = 1 second. This assumes that OAM management is enabled using the oam-pvc or oam-svc command. The up-count argument does not apply to SVCs.
Interface-ATM-VC configuration (for an ATM PVC or SVC)
VC-class configuration (for a VC class)

Use the protocol command in the appropriate command mode to do one or both of the following:
Use the no form of this command to remove a static map or disable Inverse ARP.
protocol protocol {protocol-address | inarp} [[no] broadcast]
protocol | Choose one of the following keywords: aarp---AppleTalk ARP apollo---Apollo domain appletalk---AppleTalk arp---IP ARP bridge---bridging bstun---block serial tunnel cdp---Cisco Discovery Protocol clns---ISO CLNS clns_es---ISO CLNS end system clns_is---ISO CLNS intermediate system cmns---ISO CMNS compressedtcp---Compressed TCP decnet---DECnet decnet_node---DECnet node decnet_prime_router---DECnet prime router decnet_router-l1---DECnet router L1 decnet_router-l2---DECnet router L2 dlsw---data link switching ip---IP ipx---Novell IPX llc2---llc2 |
| pad---PAD links qllc---Qualified Logical Link Control protocol rsrb---remote source-route bridging snapshot---snapshot routing support stun---serial tunnel vines---Banyan VINES xns---Xerox Network Systems protocol |
protocol-address | Destination address that is being mapped to a PVC. |
inarp | (Only valid for IP and IPX protocols on PVCs) Use this keyword to enable Inverse ARP on an ATM PVC. If you specify a protocol-address instead of inarp, Inverse ARP is automatically disabled for that protocol. |
[no] broadcast | (Optional) broadcast indicates that this map entry is used when the corresponding protocol sends broadcast packets to the interface-. For example, IGRP updates. Pseudobroadcasting is supported. The broadcast keyword of the protocol command takes precedence if you previously configured the broadcast command on the ATM PVC or SVC. |
Inverse ARP is enabled for IP and IPX if the protocol is running on the interface and no static map is configured.
Interface-ATM-VC configuration (for an ATM PVC or SVC)
VC-class configuration (for a VC class)
This command first appeared in Cisco IOS Release 11.3 T.
If the protocol command is not explicitly configured on an ATM PVC or SVC, the VC inherits the following default configuration (listed in order of next highest precedence):
The following example creates a static map on a VC, indicates that 192.68.34.237 is connected to this VC, and sends ATM pseudobroadcasts:
protocol ip 192.68.34.237 broadcast
The following example enables Inverse ARP for IPX and does not send ATM pseudobroadcasts:
protocol ipx inarp no broadcast
The following example removes a static map from a VC and restores the default behavior for Inverse ARP (Refer to the "Default" section described above):
no protocol ip 192.68.34.237
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 7200 and 7500 series routers, this value ranges from 0 to 255; on the Cisco 4500 and 4700 routers, this value ranges from 0 to 1 less than the quotient of 8192 divided by the value set by the atm vc-per-vp command. 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).
Interface configuration
This command first appeared in Cisco IOS Release 11.3 T.
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. Both vpi and vci cannot 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 next highest 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:
pvc cisco 0/5 qsaal exit
