Chapter35 Troubleshooting
Recovering from a Command Switch Failure
Step 12 When prompted for the enable secret and enable passwords, enter the passwords of the failed command
switch again.
Step 13 When prompted, make sure to enable the switch as the cluster command switch, and press Return.
Step 14 When prompted, assign a name to the cluster, and press Return.
The cluster name can be 1 to 31 alphanumeric characters, dashes, or underscores.
Step 15 After the initial configuration displays, verify that the addresses are correct.
Step 16 If the displayed information is correct, enter Y, and press Return.
If this information is not correct, enter N, press Return, and begin again at Step 9.
Step 17 Start your browser, and enter the IP address of the new command switch.
Step 18 From the Cluster menu, select Add to Cluster to display a list of candidate switches to add to the cluster.
Replacing a Failed Command Switch with Another Switch
To replace a failed command switch with a switch that is command-capable but not part of the cluster,
follow these steps:
Step 1 Insert the new switch in place of the failed command switch, and duplicate its connections to the cluster
members.
Step 2 Start a CLI session on the new command switch.
You can access the CLI by using the console port or, if an IP address has been assigned to the switch, by
using Telnet. For details about using the console port, refer to the switch hardware installation guide.
Step 3 At the switch prompt, enter privileged EXEC mode:
Switch> enable
Switch#
Step 4 Enter the password of the failed command switch.
Step 5 Use the setup program to configure the switch IP information.
This program prompts you for IP address information and passwords. From privileged EXEC mode,
enter setup, and press Return.
Switch# setup
