Chapter 5 Managing Switch Stacks
Understanding Switch Stacks
Stack master election
specifically determined
by the EMI software
Assuming that all stack members have the
same priority value:
1. Make sure that one stack member has
the noncryptographic EMI software
installed and that the other stack
member has the cryptographic SMI
software installed.
2. Restart both stack members at the same
time.
The stack member with the noncryptographic EMI
software is elected stack master.
Stack master election
specifically determined
by the cryptographic SMI
software
Assuming that all stack members have the
same priority value:
1. Make sure that one stack member has
the cryptographic SMI software
installed and that the other stack
member has the noncryptographic SMI
software installed.
2. Restart both stack members at the same
time.
The stack member with the cryptographic SMI
software is elected stack master.
Stack master election
specifically determined
by the MAC address
Assuming that both stack members have the
same priority value, configuration file, and
software image, restart both stack members
at the same time.
The stack member with the lower MAC address is
elected stack master.
Stack member number
conflict
Assuming that one stack member has a
higher priority value than the other stack
member:
1. Ensure that both stack members have
the same stack member number. If
necessary, use the switch
current-stack-member-number
renumber new-stack-member-number
global configuration command.
2. Restart both stack members at the same
time.
The stack member with the higher priority value
retains its stack member number. The other stack
member has a new stack member number.
Add a stack member
1. Power off the new switch.
2. Through their StackWise ports, connect
the new switch to a powered-on switch
stack.
3. Power on the new switch.
The stack master is retained. The new switch is
added to the switch stack.
