Catalyst 9300 auto-upgrade enable

[CodyH]

Hello,

I have a C9300-48U stack running software version 17.03.03 and will be adding another switch to the stack in the near future.  I want to know if the new switch will automatically upgrade to the running software version (17.03.03) of the stack.  I see that there is a command to enable this feature (software auto-upgrade enable).  My question is, how do I check to see if this command is already enabled?  Also, If I need to enable this, do I enable it on the new switch or on the existing stack?

Thank you in advance!

Hi,

According to the link below, the auto-upgrade command is used in a StackWise Virtual setup and not regular stacking.

https://www.cisco.com/c/en/us/support/docs/switches/catalyst-9300-series-switches/216231-upgrade-guide-for-cisco-catalyst-9000-sw.html#anc9

To add a switch to a regular stack, you would need to install the same license and IOS version to the new switch offline and than add it to the stack.

That works.  Thank you Leo Laohoo and Reza Sharifi

It can be used on normal stack, I just did in on three C9300 stacks, here's the real-life guide:

1) connect switch with different SW version to the stack, just make sure you have the same license level (essentials or advantage), new switch with appear in "V-Mismatch" state

SWITCH#show switch

2) issue command software auto-upgrade enable on the existing stack

3) stack will check for the switch with wrong SW and will start the process of upgrading and adding new switch to the stack

4) after several minutes new switch is successfully added to the stack
