Configuring PVPCs
166 Avidia System Configuration and Management User Manual
Adding a Backup PVPC to an Existing Cell Channel Card PVPC
You can configure backup PVPCs at the same time you configure a primary PVPC, as described
in the previous section. However, you can also add a backup PVPC to an existing primary PVPC
configuration.
From the
::
pvpc
=>
prompt, type the backup command in the following format:
backup <index> [<lport> <vpi>]
Parameters
<index>
The PVPC Table row index number of the primary PVPC for which you want to configure
a backup PVPC.
[<lport> <vpi>]
(Optional) Configures a backup PVPC using the specified destination port (format
slot.port), and VPI. Use the line card port (format slot.port) for the destination port. The
VPI value can either be the same value as the primary PVPC or a different value. Omitting
this parameter automatically establishes a backup PVPC on the other line card using the
same VPI as the primary PVPC.
Examples
::pvpc=> backup 3 12.1 25
::pvpc=> backup 3
Restoring Service from a Backup PVPC to a Primary Cell Channel Card
