Chapter 28 Troubleshooting
Using Recovery Procedures
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
to configure each interface on the system
Would you like to enter basic management setup? [yes/no]:
Step 6 Enter Y at the first prompt.
The prompts in the setup program vary depending on the switch you selected to be the command switch:
Continue with configuration dialog? [yes/no]: y
or
Configuring global parameters:
If this prompt does not appear, enter enable, and press Return. Enter setup, and press Return to start
the setup program.
Step 7 Respond to the questions in the setup program.
When prompted for the host name, recall that on a command switch, the host name is limited to 28
characters. Do not use -n, where n is a number, as the last characters in a host name for any switch.
When prompted for the Telnet (virtual terminal) password, recall that it can be from 1 to 25 alphanumeric
characters, is case sensitive, allows spaces, but ignores leading spaces.
Step 8 When prompted for the enable secret and enable passwords, enter the passwords of the failed command
switch again.
Step 9 When prompted, make sure to enable the switch as the cluster command switch, and press Return.
Step 10 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 11 When the initial configuration displays, verify that the addresses are correct.
Step 12 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 13 Start your browser, and enter the IP address of the new command switch.
Step 14 From the Cluster menu, select Add to Cluster to display a list of candidate switches to add to the cluster.
Recovering from Lost Member Connectivity
Some configurations can prevent the command switch from maintaining contact with member switches.
If you are unable to maintain management contact with a member, and the member switch is forwarding
packets normally, check for these conflicts:
• A member switch (Catalyst 3550, Catalyst 3500 XL, Catalyst 2950, Catalyst 2900 XL, Catalyst
2820, and Catalyst 1900 switch) cannot connect to the command switch through a port that is
defined as a network port.
• Catalyst 3500 XL, Catalyst 2900 XL, Catalyst 2820, and Catalyst 1900 member switches must
connect to the command switch through a port that belongs to the same management VLAN.
• A member switch (Catalyst 3550, Catalyst 2950, Catalyst 3500 XL, Catalyst 2900 XL,
Catalyst 2820, and Catalyst 1900 switch) connected to the command switch through a secured port
can lose connectivity if the port is disabled because of a security violation.
