  • 1. Using the Auto-Upgrade feature on the cisco Catalyst 3850 Introduction There are a number of scenarios when you would need to introduce a new switch into an existing stack of 3850 switches. One particular example is when a new switch is purchased to expand the number of usable ports in the stack. To successfully add a new switch to a stack, you will need to ensure that the same software version is running on the new switch. Prior to IOS-XE release 3.3.1, the only way to ensure the versions matched was to stage the new switch prior to introducing it into the stack. Prerequisites The 3850, includes a feature called “Auto-Upgrade” which might be familiar if you are migrating from the 3750 series platform. The goal of this feature is to ensure that any newly added switch will automatically be provisioned by the stack members with the running IOS-XE version. ** Auto-upgrade is disabled by default. ** Auto-upgrade is not available in bundle mode. To utilize the “Auto-Upgrade” feature, you simply need to add the command “software auto-upgrade enable” in the running configuration of the existing stack. This will ensure that any newly added stack members will automatically be upgraded. Configure Once the switch is stacked and booted up, you will see a clear indication that there is a mismatch in versions and the new member will not fully join the stack. If you watch the syslog as the switch is trying to join, you will notice the “auto advise” feature will alert you that the newly added switch is running a different software version and mode. %STACKMGR-1-STACK_LINK_CHANGE: STANDBY: 1 stack-mgr: Stack port 2 on switch 1 is up (3850-Stack-1) %STACKMGR-1-STACK_LINK_CHANGE: 2 stack-mgr: Stack port 1 on switch 2 is up 1

  • 3. Enable the auto-upgrade feature In global configuration mode, type the command “software auto-upgrade enable.” This will enable the feature for any new switches that join the stack. 3850-Stack(config)#software auto-upgrade enable 3850-Stack(config)#end You will now have to reload the newly added switch only, a full stack reload is not necessary. In my case, the newly added switch is “switch 3” so I simply type “reload slot 3.” Remember that “slot” designates the switch in the stack (slot 1 = switch 1) 3850-Stack#reload slot 3 Proceed with reload? [confirm] %STACKMGR-1-RELOAD_REQUEST: 1 stack-mgr: Received reload request for switch 3, reason Reload Slot Command %STACKMGR-1-STACK_LINK_CHANGE: 1 stack-mgr: Stack port 2 on switch 1 is down %STACKMGR-6-SWITCH_REMOVED: 1 stack-mgr: Switch 3 has been removed from the stack. %STACKMGR-1-STACK_LINK_CHANGE: STANDBY:2 stack-mgr: Stack port 1 on switch 2 is down (3850-Stack-2) Starting SWITCH-DELETE sequence, switch 3 SWITCH-DELETE sequence complete, switch 3 %STACKMGR-6-SWITCH_REMOVED: STANDBY:2 stack-mgr: Switch 3 has been removed from the stack.
