Switch Stack Configuration Scenarios - Cisco WS-C3750-48PS-S Software Configuration Manual

Chapter 5 Managing Switch Stacks
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.
The stack member with the cryptographic EMI
software is elected stack master.
