Recovering from a Command Switch Failure

This section describes how to recover from a failed command switch. You can configure a redundant
command switch group by using the Hot Standby Router Protocol (HSRP). For more information, see
Chapter 7, "Clustering Switches."
Note HSRP is the preferred method for supplying redundancy to a cluster.
If you have not configured a standby command switch, and your command switch loses power or fails
in some other way, management contact with the member switches is lost, and you must install a new
command switch. However, connectivity between switches that are still connected is not affected, and
the member switches forward packets as usual. You can manage the members as standalone switches
through the console port or, if they have IP addresses, through the other management interfaces.
You can prepare for a command switch failure by assigning an IP address to a member switch or another
switch that is command-capable, making a note of the command-switch password, and cabling your
cluster to have redundant connectivity between the member switches and the replacement command
switch. This section describes two solutions for replacing a failed command switch:
•
•
For information on command-capable switches, refer to the release notes.
