Adding an Extreme switch to an existing stack

A recent Extreme switch installation went without a hitch on installation weekend, and the Monday following we were there to support the client in the event of any issues. Luckily there weren’t any. However on the Tuesday we had a single stack member switch, an Extreme x460-48p, stop passing traffic to any users that were patched into this switch. We had the challenge of adding an Extreme switch to an existing stack.

We took a spare x460-48p to site and added it to the stack by using the following steps :

On the new switch:

  • Update the firmware to be the same as on all other stack members
  • Run the command
    enable stacking
  • Choose not to use Easy Setup and do not reboot. Issue commands
    configure stacking protocol enhanced
    configure stacking node-address 01:02:03:04:05:06 slot-number 4
  • Where 01:02:03:04:05:06 is the MAC of the new switch and 4 is the slot number of the new switch.
    reboot


On the existing stack Master:

  • Run the command
    synchronize stacking node-address 01:02:03:04:05:06
  • Where 01:02:03:04:05:06 is the MAC of the new switch
