  • Bonded Pair
  1.  Save the running configuration on the existing VSB system with command: show config outfile slot<N>/BACKUP.CFG (where N is the slot number of the chassis that will remain in the VSB system).
  2. Copy off the configuration via a TFTP server with command: copy slot<N>/BACKUP.CFG tftp://IP_ADDRESS/BACKUP.CFG
  3. Configure the replacement unit for bonding with commands:
  5. Type set bonding chassis <UNIQUE CHASSIS #> system-id <MATCHING ID#>
  6. Type set bonding chassis <MATCHING SECRET>
  7. Type set bonding port <PORT_STRING> enable
  8. Type set bonding port <PORT_STRING> enable
  9. If using Link Failure Response cables, ensure to enable bonding on the LFR ports, and also type set bonding lfr enable
  10. Type set bonding enable
  11. The replacement unit will reboot. Connect bonding cables after unit has fully booted.
  12. Different firmware on the replacement than the master causes a second reboot to load firmware
  13. Copy configuration onto switch with command: copy tftp://IP_ADDRESS/BACKUP.CFG slot<N>/BACKUP.CFG
  14. Reload configuration from file created using step 1 type: configure slot<N>/BACKUP.CFG append
IMPORTANT NOTE: If your configuration contains any 40GB ports such as fg.x.x that have been configured as 10gb ports (command in config would be "set port speed fg.X.X 10000"), you will need to reboot the replacement switch and re-append the configuration one more time as the new tg.x.x port commands will error upon the first append as they don't yet exist
