I was asked if any precautions need to be taken when adding a new WS-C3750-24PS-S to a stack that has 1 x WS-C3750-24PS-S and 4 x WS-C3750-24tS-S:
I said that the new switch:
1. Must have the same IOS as the existing stack members which is c3750-i9-mz.121-19.EA1d
2. The priority of the new switch must be 1 since the current master is 1.
3. the vlan.dat of the new switch must be deleted before adding the new switch to the stack
4. The config of the new switch must be erased before the new switch is added.
Is there anything else I missed.
