Preconfigure a Switch

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. 

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.

Issue the member <unit-id> <switchindex> command. To view the supported unit 
types, use the show supported switchtype command. 

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. 

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 <unit-id> 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 

Stack master election specifically 
determined by the MAC address.

Assuming that both stack members 

have the same priority value and 
firmware image, restart both stack 
members at the same time.

The stack member with the higher 
MAC address is elected stack 
master.

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.

The stack master is retained. The 
new switch is added to the switch 
stack.

Stack master failure.

Remove (or power off) the stack 
master.

One of the remaining stack 
members becomes the new stack 
master. All other members in the 
stack remain stack members and 
do not reboot.
