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:
Note

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:
  1. 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
  2. Ensure that the standalone switch has an IP address or DHCP. See Zero Touch Provisioning (Auto Configuration).
  3. 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

    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.
  4. On the standalone switch, confirm that the stacking links are configured correctly. Run the command show stacking. The following should appear (see bold text):
    # show stacking

  5. On the standalone switch, run the command run script clone.py from ipaddress -s 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.
    The following appears:
    # run script clone.py from 10.68.69.94 -s 0
