Scenario
Stack master election
specifically determined
by the cryptographic
software image and the IP
services feature set and
the IP services feature set
Stack master election
specifically determined
by the cryptographic
software image and the IP
base feature set
Stack master election
specifically determined
by the MAC address
Stack member number
conflict
Add a stack member
OL-21521-01
Assuming that all stack members have the
same priority value:
Make sure that one stack member has
1.
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.
Restart both stack members at the same
2.
time.
Assuming that all stack members have the
same priority value:
Make sure that one stack member has
1.
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.
Restart both stack members at the same
2.
time.
Assuming that both stack members have the
same priority value, configuration file, and
feature set, restart both stack members at
the same time.
Assuming that one stack member has a
higher priority value than the other stack
member:
Ensure that both stack members have
1.
the same stack member number. If
necessary, use the switch
current-stack-member-number
renumber new-stack-member-number
global configuration command.
Restart both stack members at the same
2.
time.
Power off the new switch.
1.
Through their StackWise Plus ports,
2.
connect the new switch to a powered-on
switch stack.
Power on the new switch.
3.
Result
The stack member with the cryptographic image and
the IP services feature set is elected stack master.
Only Catalyst 3650-E or 3750 switches
Note
running Cisco IOS Release 12.2(53)SE or
earlier could be running the
noncyrptographic image.
The stack member with the cryptographic image and
the IP base feature set is elected stack master.
Only Catalyst 3650-E or 3750 switches
Note
running Cisco IOS Release 12.2(53)SE or
earlier could be running the
noncyrptographic image.
The stack member with the lower MAC address is
elected stack master.
The stack member with the higher priority value
retains its stack member number. The other stack
member has a new stack member number.
The stack master is retained. The new switch is
added to the switch stack.
