Managing Switch Stacks

Stack Management Connectivity
You manage the stack and the member interfaces through the master. You can use the CLI, SNMP,
Network Assistant, and CiscoWorks network management applications. You cannot manage members as
individual switches.

Stack Through an IP Address
The stack is managed through a system-level IP address. You can still manage the stack through the same
IP address even if you remove the master or any other stack member from the stack, provided there is IP
connectivity.
Members keep their IP addresses when you remove them from a stack. To avoid having two devices with
Note
the same IP address in your network, change the IP address of the switch that you removed from the
stack.

Stack Through an SSH Session
The Secure Shell (SSH) connectivity to the stack can be lost if a master running the cryptographic
version fails and is replaced by a switch that is running a noncryptographic version. We recommend that
a switch running the cryptographic version of the software be the master.
Stack Through Console Ports
You can connect to the master through the console port of one or more members.
Be careful when using multiple CLI sessions to the master. Commands that you enter in one session are
not displayed in the other sessions. Therefore, it is possible that you might not be able to identify the
session from which you entered a command.
We recommend that you use only one CLI session when managing the stack.
