Dell EMC Networking OS6 How to Automatically Synchronize Firmware when Adding an N-Series Switch to a Stack


This article explains how to use the boot auto-copy-sw and no boot auto-copy-sw allow-downgrade commands on the stack master to enable automatic firmware synchronization.





This procedure applies to adding a new member to an existing stack. If you are replacing an existing stack member please contact technical support for assistance with additional steps that will be required.

The optional boot auto-copy-sw allow-downgrade command should be used cautiously, as it does not assure configuration migration and is enabled by default once Firmware Synchronization is enabled. Pease contact technical support for assistance with this command.

  1. Enable Stack Firmware Synchronization on the stack master.

N-SeriesMaster>en

N-SeriesMaster#show switch

N-SeriesMaster#show auto-copy-sw

Stack Firmware Synchronization

Synchronization................................ Disabled

SNMP Trap status............................... Enabled

allow-downgrade................................ Enabled

N-SeriesMaster#conf

N-SeriesMaster(config)#boot auto-copy-sw

N-SeriesMaster(config)#no boot auto-copy-sw allow-downgrade

N-SeriesMaster(config)#end

N-SeriesMaster#copy running-config startup-config

This operation may take a few minutes.

Management interfaces will not be available during this time.

  1. Power down the switch to be added to the stack.

  2. Connect the stacking cables.

  3. Power up the switch to be added to the stack.

  4. Verify the new switch has been added to the stack and the firmware has been synchronized.
