Now I understand. So if you are stacking the two switches, you do not need to migrate the configuration over to the second switch. Stacking takes care of that.
Now that said, since you want to use base ports for stacking, we only support the use of ports 0/0/22 (24 port switches), 0/0/23 (24 port switches), 0/0/46 (48 port switches) or 0/0/47 (48 port switches) for that. By default these ports are treated like normal ports so you need to change them to stacking ports. To do that, issue the following on the CLI of the active switch
add stacking interface stack 0/47
* Assumes you want to use port 0/0/47
If this a two member stack, use the following configuration and remember to save.
!
stack-profile
no split-detection
member-id 0 election-priority 255
member-id 1 election-priority 255
!
Then on the second (new switch) first make sure the configuration has been defaulted (restore factory_default stacking). It will then reboot. Once it is up and running, issue the following:
add stacking interface stack 0/47
* Assumes you want to use port 0/0/47
Now connect the two switches and the second (new switch) should become part of the stack.
Remember that both switches must be running the same version of AOS. Base port stacking was added in 7.2.1.0. The latest maintenance release on our site is 7.2.2.1.
