cluster standby-group Chapter 2 Catalyst 3560 Switch Cisco IOS Commands 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. cluster standby-group HSRP-group-name [routing-redundancy] no cluster standby-group Syntax Description HSRP-group-name routing-redundancy Name of the HSRP group that is bound to the cluster. The group name is limited to 32 characters. (Optional) Enable the same HSRP standby group to be used for cluster command-switch redundancy and routing redundancy. Defaults The cluster is not bound to any HSRP group. Command Modes Global configuration Command History Release 12.1(19)EA1 Modification This command was introduced. 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 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.) Examples This example shows how to bind the HSRP group named my_hsrp to the cluster. This command is executed on the cluster command switch. Switch(config)# cluster standby-group my_hsrp This example shows how to use the same HSRP group named my_hsrp for routing redundancy and cluster redundancy. Switch(config)# cluster standby-group my_hsrp routing-redundancy 2-64 Catalyst 3560 Switch Command Reference 78-16405-05
