Clustering Switches
TACACS+
If Terminal Access Controller Access Control System Plus (TACACS+) is configured on the command
switch, TACACS+ must also be configured on all member switches to access the switch cluster from
CMS. For more information about TACACS+, see the
Access Modes in CMS
CMS provides only two levels of access to the configuration options. If you have privilege level 15
access to the switch, you have access to all configuration options from CMS. Any privilege level lower
than 15 means you have read-only access to CMS. For more information about CMS access modes, see

Management VLAN
Communication with the switch management interfaces is through the command-switch IP address. The
IP address is associated with the management VLAN, which by default is VLAN 1. To manage switches
in a cluster, the command switch, member switches, and candidate switches must be connected through
ports that belong to the command-switch management VLAN.
Caution
You can change the management VLAN through a console connection without interrupting the console
connection. However, changing the management VLAN ends your CMS session. Restart your CMS
session by entering the new IP address in the browser Location field (Netscape Communicator) or
Address field (Microsoft Internet Explorer), as described in the release notes.
You can change the management VLAN of a member switch (not the command switch); however, the
command switch will not be able to communicate with it. In this case, you will need to manage the switch
as a standalone switch.

Catalyst 2900 XL or Catalyst 3500 XL member switches running Cisco IOS
Release 12.0(5)WC2 or earlier
–
Catalyst 2950 member switches running Cisco IOS Release 12.0(5)WC2 or earlier
–
Catalyst 3550 member switches running Cisco IOS Release 12.1(6)EA1 or earlier
