Table 1. Switch Stack Master Scenarios (Continued)
Scenario Action Result
Stack master election specifically
determined by the MAC address.
Preconfigure a Switch
Assuming that both stack members
have the same priority value and
firmware image, restart both stack
members at the same time.
Add a stack member. • Power off the new switch
• Through their stacking ports, connect
the new switch to a powered-on
switch stack.
• Power on the new switch.
Stack master failure. Remove (or power off) the stack
master.
You can preconfigure (supply a configuration to) a new switch before it joins the switch stack.
You can specify the stack member number, the switch type, and the interfaces associated
with a switch that is not currently part of the stack.
Note: If you are replacing a switch with the same model in the same
position in the stack, you do not need to preconfigure it. The new
switch assumes the same configuration as the previous switch.
1. Issue the member command. To view the supported unit
types, use the show supported switchtype command.
2. Next, configure the unit you just defined with configuration commands, just as if the unit
were physically present.
Ports for the preconfigured unit come up in a detached state.
The stack member with the higher
MAC address is elected stack
master.
The stack master is retained. The
new switch is added to the switch
stack.
One of the remaining stack
members becomes the new stack
master. All other members in the
stack remain stack members and
do not reboot.
3. To see the ports, use the show port all command. Now you can configure the detached
ports for VLAN membership and any other port-specific configuration.
After you preconfigure a unit type for a specific unit number, attaching a unit with different unit
type for this unit number causes the switch to report an error. The show switch command
indicates config mismatch for the new unit and the ports on that unit don’t come up. To
resolve this situation, you can change the unit number of the mismatched unit or delete the
preconfigured unit type using the no member command.
When you add a preconfigured switch to the switch stack, the stack applies either the
preconfigured configuration or the default configuration. The following table lists the events
