Chapter 5 Managing Switch Stacks Understanding Switch Stacks
Stack master election
specifically determined
by the cryptographic
software image and the IP
services feature set and
the IP services feature set
Assuming that all stack members have the
same priority value:
1. Make sure that one stack member has
the cryptographic image installed and
the IP services feature set enabled and
that the other stack member has the
noncryptographic image installed and
the IP services feature set enabled.
2. Restart both stack members at the same
time.
The stack member with the cryptographic image and
the IP services feature set is elected stack master.
Note Only Catalyst 3650-E or 3750 switches
running Cisco IOS Release 12.2(53)SE or
earlier could be running the
noncyrptographic image.
Stack master election
specifically determined
by the cryptographic
software image and the IP
base feature set
Assuming that all stack members have the
same priority value:
1. Make sure that one stack member has
the cryptographic image installed and
the IP base feature set enabled and that
the other stack member has the
noncryptographic image installed and
the IP base feature set enabled.
2. Restart both stack members at the same
time.
The stack member with the cryptographic image and
the IP base feature set is elected stack master.
Note Only Catalyst 3650-E or 3750 switches
running Cisco IOS Release 12.2(53)SE or
earlier could be running the
noncyrptographic image.
Stack master election
specifically determined
by the MAC address
Assuming that both stack members have the
same priority value, configuration file, and
feature set, 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 Plus 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.
