Understanding Switch Stacks
Switch Stack Configuration Scenarios
Table 1-2 provides switch stack configuration scenarios. Most of the scenarios assume that at least two
switches are connected through their StackWise Plus ports.
Table 1-2 Switch Stack Configuration Scenarios
Scenario Result
Stack master election
specifically determined
by existing stack masters Connect two powered-on switch stacks
through the StackWise Plus ports. Only one of the two stack masters becomes the new
stack master. None of the other stack members
become the stack master.
Stack master election
specifically determined
by the stack member
priority value 1. Connect two switches through their
StackWise Plus ports.
2.
Use the switch stack-member-number
priority new-priority-number global
configuration command to set one stack
member with a higher member priority
value.
3. Restart both stack members at the same
time.
The stack member with the higher priority value is
elected stack master.
Stack master election
specifically determined
by the configuration file Assuming that both stack members have the
same priority value:
1.
Make sure that one stack member has a
default configuration and that the other
stack member has a saved (nondefault)
configuration file.
2.
Restart both stack members at the same
time.
The stack member with the saved configuration file
is elected stack master.
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.
