Chapter 8 Permanent Virtual Connections (PVCs and PVPs)

Creating a PVP connection
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.
Figure 8.2 A PVP Connection
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>]
Example 1: 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
Example 2: Setting up a PVP between 2 ports on different modules on the same
switch, with traffic descriptors:
M15-155s6:/>pvp setup 6.3.7 9.1.7 3
M15-155s9:/>pvp setup 6.3.7 9.1.7 3
Parameters: <vpl1index> The first VPL for the PVP connection in the format
<slot.port number.vpi>.
<vpl2index> The first VPL for the PVP connection in the format
<slot.port number.vpi>.
td1 Index of rx td for vpl1 (= tx td for vpl2)
td2 <td2> = index of tx td for vpl1 (= rx td for vpl2)
