Cisco IOS Releases 12.0(29)S and 12.2(25)S

atm pvp

To create a permanent virtual path (PVP) used to multiplex (or bundle) one or more virtual circuits

(VCs), use the atm pvp command in interface configuration mode. To remove a PVP, use the no form

of this command.

atm pvp vpi [peak-rate] [l2transport]

no atm pvp vpi

Syntax Description

Defaults PVP is not configured.

The default peak rate is the line rate.

Command Modes Interface configuration

Command History

Usage Guidelines This command is commonly used to create a PVP that is used in multiplex circuit emulation service

(CES) and data VCs.

The ATM-CES port adapter supports multiplexing of one or more VCs over a virtual path that is shaped

at a constant bandwidth. For example, you can buy a virtual path service from an ATM service provider

and multiplex both the CES and data traffic over the virtual path.

All subsequently created VCs with a vpi argument matching the vpi value specified with the atm pvp

command are multiplexed onto this PVP. This PVP connection is an ATM connection where switching

is performed on the VPI field of the cell only. A PVP is created and left up indefinitely. All VCs that are

multiplexed over a PVP share and are controlled by the traffic parameters associated with the PVP.

vpi ATM network virtual path identifier (VPI) of the VC to multiplex on the permanent

virtual path. The range is from 0 to 255. 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.

The number specified for the vpi argument must not already exist. If the number

specified for the vpi argument is already being used by an existing VC, this command

is rejected.

peak-rate (Optional) Maximum rate in kbps at which the PVP can send data. The range is 84 kbps

to line rate. The default is the line rate.

l2transport (Optional) Specifies that the PVP is for the Any Transport over MPLS (AToM) ATM

cell relay feature or the ATM Cell Relay over L2TPv3 feature.
