Adding a Backup PVCC to an Existing Cell Channel Card PVCC
You can configure backup PVCCs at the same time you configure a primary PVCC, as
described in the previous section. However, you can also add a backup PVCC to an existing
primary PVCC configuration.
From the
::pvcc=>
prompt, type the backup command in the following format:
backup <index> [<lport> <vpi> <vci>]
Parameters
<index>
The PVCC Table row index number of the primary PVCC for which you want to configure
a backup PVCC.
[<lport> <vpi> <vci>]
(Optional) Configures a backup PVCC using the specified destination port (format
slot.port), VPI and VCI. Use the line card port (format slot.port) for the destination port.
The VPI and VCI values can either be the same values as the primary PVCC or different
values. Omitting this parameter automatically establishes a backup PVCC on the other line
card using the same VPI and VCI as the primary PVCC.
Examples
::pvcc=> backup 3 12.1 0 100
::pvcc=> backup 3
Restoring Service from a Backup PVCC to a Primary Cell Channel Card
