8.7 Configuring PVC standby groups of frame relay

switching

8.7.1 Establishing the configuration task

Applicable environment

You can configure the switching PVC backup function to guarantee better services for FR
switching.

There are two methods you use for configuring the PVC backup function:

Backing up PVC through FR switching PVC

You do not need to specially create the PVC standby groups of FR switching. To back up

the switching PVC, if the specified standby group does not exist, the system

automatically creates a standby group with the number and adds the switching PVC into

the group.

The system supports up to 256 standby groups, numbered from 1 to 256.

• Backing up outbound PVC through the tTunnel interface through FR over IP.

Run the FR PVC standby group command to back up the related outbound interface to

the Tunnel interface. You can then back up the FR switching link through FR over IP in

all the cases except when the two interfaces are Tunnel interfaces.

The PVC standby groups of FR switching can implement switching in two modes: the

automatic switching mode and the manual switching mode.

For the switchover from the standby to master, only the manual mode is supported.

ED NOTE

A standby PVC corresponds only to a master PVC.Tthe newly configured master PVC overwrites the
previous PVC in the same standby PVC.

Preconfiguration tasks

Before configuring PVC standby groups of FR switching, complete the following tasks:
