Cluster Standby-Group - Cisco Catalyst 2950 Command Reference Manual

cluster standby-group

cluster standby-group
Use the cluster standby-group global configuration command to enable command switch redundancy
by binding the Hot Standby Router Protocol (HSRP) standby group to the cluster. Use the no form of
this command to unbind the cluster from the HSRP standby group.
Syntax Description
HSRP-group-name
Defaults
The cluster is not bound to any HSRP group.

Command History Release

Usage Guidelines
You must enter this command only on the command switch. If you enter it on a member switch, an error
message appears.
The command switch propagates the cluster-HSRP binding information to all members. Each member
switch stores the binding information in its nonvolatile RAM (NVRAM).
The HSRP group name must be a valid standby group; otherwise, the command entry produces an error.
Use the same group name on all members of the HSRP standby group that is to be bound to the cluster.
Use the same HSRP group name on all cluster-HSRP capable members for the HSRP group that is to be
bound. (When not binding a cluster to an HSRP group, you can use different names on the cluster
command and the member switches.)
Examples
This example shows how to bind the HSRP group named my_hsrp to the cluster. This command is
entered on the command switch.
Switch(config)# cluster standby-group my_hsrp
This example shows the error message when this command is entered on a command switch and the
specified HSRP standby group does not exist:
Switch(config)# cluster standby-group my_hsrp
%ERROR:Standby (my_hsrp) group does not exist
