Connectivity To Specific Stack Members; Switch Stack Configuration Scenarios - Cisco Catalyst 3750-X Software Configuration Manual

Understanding Switch Stacks
Be careful when using multiple CLI sessions to the stack 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 using only one CLI session when managing the switch stack.

Connectivity to Specific Stack Members

If you want to configure a specific stack member port, you must include the stack member number in the
CLI command interface notation. For more information, see the
section on page
To debug a specific stack member, you can access it from the stack master by using the session
stack-member-number privileged EXEC command. The stack member number is appended to the system
prompt. For example,
system prompt for the stack master is
CLI session to a specific stack member.

Result
Only one of the two stack masters becomes the new
stack master. None of the other stack members
become the stack master.
The stack member with the higher priority value is
elected stack master.
The stack member with the saved configuration file
is elected stack master.
