This chapter explains the function and syntax of the ATM commands: oam-pvc through show atm traffic. For more information about defaults and usage guidelines, see the corresponding chapter of the Cisco IOS Wide-Area Networking Command Reference, Release 12.1.
To enable end-to-end F5 Operation, Administration, and Maintenance (OAM) loopback cell generation and OAM management for an ATM permanent virtual circuit (PVC) or VC class, use the oam-pvc command in the appropriate command mode. To disable generation of OAM loopback cells and OAM management, use the no form of this command.
oam-pvc [manage] [frequency]
Syntax Description
manage (Optional) Enable OAM management. frequency (Optional) Time delay (0 to 600 seconds) between transmitting OAM loopback cells.
To configure parameters related to Operation, Administration, and Maintenance (OAM) management for an ATM permanent virtual circuit (PVC), switched virtual circuit (SVC), VC class, or VC bundle, use the oam retry command in the appropriate command mode. To remove OAM management parameters, use the no form of this command.
oam retry up-count down-count retry-frequency
Syntax Description
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 Frequency (in seconds) at which end-to-end F5 OAM loopback cells are transmitted when a change in the 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) argument is specified using the oam-pvc command, then loopback cells are sent at the retry-frequency to verify whether the PVC is down.
To enable end-to-end F5 Operation, Administration, and Maintenance (OAM) loopback cell generation and OAM management for an ATM switched virtual circuit (SVC) or VC class, use the oam-svc command in the appropriate command mode. To disable generation of OAM loopback cells and OAM management, use the no form of this command.
oam-svc [manage] [frequency]
Syntax Description
manage (Optional) Enables OAM management. frequency (Optional) Time delay (0 to 600 seconds) between transmitting OAM loopback cells.
To configure a static map for an ATM permanent virtual circuit (PVC), switched virtual circuit (SVC), or VC class; or enable Inverse Address Resolution Protocol (ARP) or Inverse ARP broadcasts on an ATM PVC, use the protocol command in the appropriate command mode. To remove a static map or disable Inverse ARP, use the no form of this command.
protocol protocol {protocol-address | inarp} [[no] broadcast]
Syntax Description
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.
To create or assign a name to an ATM permanent virtual circuit (PVC), specify the encapsulation type on an ATM PVC, or enter interface-ATM-VC configuration mode, use the pvc command in interface or subinterface configuration mode. To remove an ATM PVC, use the no form of this command.
pvc [name] vpi/vci [ilmi | qsaal | smds]
Syntax Description
name (Optional) 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 signalling, 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 ordinarily are 0 and 16, respectively. qsaal (Optional) Signalling-type PVC used for setting up or tearing down SVCs; the associated vpi and vci values ordinarily are 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.
To improve data reliability by randomizing the ATM cell payload frames, use the scrambling-payload interface configuration command. To disable scrambling, use the no form of the command.
