Recovering From A Command Switch Failure; Replacing A Failed Command Switch With A Cluster Member - Cisco Catalyst 2360 Software Configuration Manual

Recovering from a Command Switch Failure

Recovering from a Command Switch Failure
This section describes how to recover from a failed command switch. For more information, see
Chapter 4, "Clustering Switches."
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, through the Ethernet management 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 provide redundant connectivity between the member switches and the replacement command
switch. These sections describe two solutions for replacing a failed command switch:
•
•
These recovery procedures require that you have physical access to the switch.
For information on command-capable switches, see the release notes.

Replacing a Failed Command Switch with a Cluster Member

To replace a failed command switch with a command-capable member in the same cluster, follow these
steps:
Disconnect the command switch from the member switches, and physically remove it from the cluster.
Step 1
Insert the member switch in place of the failed command switch, and duplicate its connections to the
Step 2
cluster members.
Start a CLI session on the new command switch.
Step 3
You can access the CLI by using the console port, by using the Ethernet management port, or, if an IP
address has been assigned to the switch, by using Telnet. For details about using the console port, see
the switch hardware installation guide. For details about using the Ethernet management port, see the
"Using the Ethernet Management Port" section on page 8-14
Step 4 At the switch prompt, enter privileged EXEC mode:
Switch> enable
Switch#
Enter the password of the failed command switch.
Step 5
Enter global configuration mode.
Step 6
Switch# configure terminal
Enter configuration commands, one per line.
Remove the member switch from the cluster.
Step 7
Switch(config)# no cluster commander-address
Return to privileged EXEC mode.
Step 8
Switch(config)# end
Switch#
