Switch Stack Configuration Scenarios
Table 4 Switch Stack Configuration Scenarios (continued)
Scenario
Stack master election
specifically determined
by the cryptographic IP
base image
Stack master election
specifically determined
by the MAC address
Stack member number
conflict
Addition of a stack
member
Cisco IOS Release 12.2(25)SEC

Action
Assuming that all stack members have the
same priority value:
Make sure that one stack member has
1.
the cryptographic IP base image
installed and that the other stack
member has the noncryptographic IP
base image installed.
Restart both stack members at the same
2.
time.
Assuming that both stack members have the
same priority value, configuration file, and
software image, restart both stack members
at the same time.
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.
Restart both stack members at the same
2.
time.
Power down the new Cisco
1.
EtherSwitch service module.
Through their StackWise ports, connect
2.
the new Cisco EtherSwitch service
module to a powered-up switch stack.
3. Power up the new Cisco EtherSwitch
service module.

Result
The stack member with the cryptographic IP base
image is elected stack master.
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 Cisco
EtherSwitch service module is added to the switch
stack.
