This window appears when you choose Cluster > Standby Command Switches on the menu bar. You can also click here to launch it. Use it to:
The Current Candidates list contains the name of all cluster members that are qualified standby switches: command-capable switches with the required software that are available to assume responsibility. If a Catalyst 3550 switch is the command switch, only Catalyst 3550 switches are command-capable. If a non-3550 switch is the command switch, only non-3550 switches are command-capable.
If cluster redundancy is not configured on the cluster, the Standby Comand Group list contains only the name of the command switch with the CC (cluster command) designation. If cluster redundancy is configured, this list contains the names of the active command (AC) switch, the standby command (SC) switch, and one or more passive standby (PC) switches. A passive standby switch replaces the switch listed above it if the current standby (SC) becomes the active command switch.
Switches listed in the Standby Command Group list make up the current cluster redundancy group. These switches share a virtual IP address that is assigned to the cluster.
Note: After a virtual IP address is assigned to the cluster redundancy group, always use the virtual IP address to access the command switch.
To create a group and enable it:
You can add any switch in the Current Candidates list to the Standby Command Group list. You can remove any switch from the Standby Command Group list except the active command (AC) switch.
