Avaya M770 ATM Switch User’s Guide

A PVP is created by constructing two VPLs. The VPLs describe the edges of the 
PVP, see Figure 8.2. Refer also to “Creating PVPs” on page 293.

PVP connections will be re-established automatically when the M770 ATM Switch 
powers up. You can have up to 64 PVP connections on a module. To set up a bi-
directional PVP between 2 ports on different modules (on the same switch) you 
must type the command on the CLI of each module.
The command described below will setup a VPL on each <slot.port.vpi> and a PVP 
connection joining the two. The PVP connection will be automatically assigned an 
ID.
To create a PVP connection, use the 

pvp setup

 command:

Command:

M15-155s6:/>pvp setup <vpl1index> <vpl2index> [<td1>] [<td2>]

Setting up a PVP between two ports on the same module with 
default traffic descriptors:

M15-155s6:/>pvp setup 6.2.8 6.3.8

Setting up a PVP between 2 ports on different modules on the same
