Command:  

pvc


Mode:

Router(config-if)#


Syntax:

pvc [name] vpi/vci [ces ilmi | qsaal | smds]

no pvc [name] vpi/vci [ces | ilmi | qsaal | smds]


Syntax Description:

name

(Optional) The name of the PVC or map. The name can be up to 15 characters long.

vpi/

ATM network virtual path identifier (VPI) for this PVC. The absence of the "/" and a vpi value defaults the vpivalue 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; on 2600 and 3600 series routers using Inverse Multiplexing for ATM (IMA), the ranges are 0 to 15, 64 to 79, 128 to 143, and 192 to 207.

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.

ces

(Optional) Circuit Emulation Service encapsulation. This keyword is available on the OC-3/STM-1 ATM Circuit Emulation Service network module only.

ilmi

(Optional) Used to set up communication with the Interim Local Management Interface (ILMI); the associated vpi and vci values ordinarily are 0 and 16, respectively.

qsaal

(Optional) A 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.

Command Description:

To create or assign a name to an ATM permanent virtual circuit (PVC), to specify the encapsulation type on an ATM PVC, and to 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.


Example:

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 signalling for an SVC. It specifies VPI 0 and VCI 5:

pvc cisco 0/5 qsaal

exit


The following example configures the PVC called "cisco" to use class-based weighted fair queueing (CBWFQ). It attaches a policy map called "policy1" to the PVC. The classes the make up "policy1" determine the service policy for the PVC:

pvc cisco 0/5
service-policy output policy1

vbr-nrt 2000 2000
encap aal5snap
