Cloning from Standalone to a Stack
You can easily add or replace a switch in a stack using the clone.py script.
When cloning to become a stacking member, additional NVRAM
attributes are copied:
- Stacking enabled
- Stack MAC address
- Slot number—either provided or derived from the stacking master
- Switch's master-capable status—using the –m option when running clone.py sets the standalone switch to be master-capable.

Note
Cloning to a standalone switch using a stacking master as the source does not make the standalone switch a stacking master. The configuration cloned from a stacking master to the standalone switch is ignored by ExtremeXOS.To clone from a standalone to a stack:
- On the stack master, run the command run script clone.py master. The
following
appears:
clone.py is started as cloning master Use "stop" option to stop cloning master services
- Ensure that the standalone switch has an IP address or DHCP. See .
- On the standalone switch, configure the switch's stacking-support options so that stacking
connectivity is ready once the switch becomes stacking enabled. Run the command enable stacking-support.
Important
You must perform this step before cloning the standalone switch. If the switch is cloned as a stacking standby switch, console login and configuration options require contacting a stack master for user authentication. If the stacking links are not configured correctly, then only failsafe login is available. - On the standalone switch, confirm that the stacking links are configured
correctly. Run the command show stacking. The following should appear (see bold
text):

STACKING_SLOT-M,
where:
- ipaddress is the IP address of the stack master.
- STACKING_SLOT is the slot number. Use 0 (zero) to have the switch given the lowest available slot number.
- -M enable this switch to be master-capable.
