Cluster Standby-Group - Cisco Catalyst 3750 Command Reference Manual

cluster standby-group

cluster standby-group
Use the cluster standby-group global configuration command to enable cluster command-switch
redundancy by binding the cluster to an existing Hot Standby Router Protocol (HSRP). Entering the
routing-redundancy keyword enables the same HSRP group to be used for cluster command-switch
redundancy and routing redundancy. Use the no form of this command to return to the default setting.
Syntax Description HSRP-group-name
routing-redundancy
Defaults
The cluster is not bound to any HSRP group.
Command Modes Global configuration
Command History Release
12.1(11)AX
Usage Guidelines Enter this command only on the cluster command switch. If you enter it on a cluster member switch, an
error message appears.
The cluster command switch propagates the cluster-HSRP binding information to all cluster-HSRP
capable members. Each cluster member switch stores the binding information in its nonvolatile RAM
(NVRAM).
The HSRP group name must be a valid standby group; otherwise, the command exits with an error.
The same group name should be used on all members of the HSRP standby group that is to be bound to
the cluster. The same HSRP group name should also be used 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 commander and the members.)
