PnP on 3850 stack

aevans — Fri, 01 Mar 2019 12:32:04 GMT

Hi All,

I am having a bit of trouble getting a stack of 3850's configured via PnP. I initially tested with just a single switch and it worked great, but since I introduced a second switch into the stack it no longer seems to register in APIC.

If I look at the logs on the serial I get "Redundant RPs - Simultaneous configs not allowed:locked from console" I don't recall seeing this output on a single switch. also If I do a "show pnp trace" I see HA, config safe check [NOT OK]. Is the PnP server trying to configure the switch before the stack is fully functional?

I'm looking to see if there is a delay setting anywhere.

I have tried with 2960x switches with no issue.

Hi Anthony,

I have been testing 3650 stacks (successfully) over the past few days.

What version of IOS are you running?

You need to have a stack rule in PnP app too.

BTW, what you are seeing is normal. There is a builtin check while stack is coming up. the PnP process retries as you can see in my example.

Hi Adam,

Thanks for getting back to me. Out of the box the installed image is 3.6.5 and as mentioned on its own worked great. I have a rule which has 2 switches in the stack.

It's good to know that what I thought was an issue is correct behaviour.

Unfortunately it looks like I've managed to trash the switches now by upgrading to version 16. They are now in a Linux boot screen in a constant loop. I will update the PnP issue once I manage to get them to boot again.

Cheers

Hi Ant,

thanks for the follow up. did you use PnP to upgrade to 16.3?
