APIC-EM PnP Option 43

bradleyconway011 — Fri, 01 Mar 2019 12:40:49 GMT

Greetings all!

I'm setting up APIC-EM (version 1.5) and running into a problem with the PnP module(also 1.5). I've set my upstream switch as the dhcp server. My 2960-X switch (running c2960x-universalk9-mz.152-2.E6) is able to get an ip address, and shows initially that option 43 is found and starts the PnP auto discover when there is no config. But it seems like it contacts controller then is unable to get the request back. Below is an output of a pnp trace. Any and all help is greatly appreciated.

Switch#sh pnp trace

I've tried putting the PnP profile in the 2960-X's config after it fails to connect to the controller. Below is it's output:

Hi Bradley,

Some basic clarification questions.

Can you ping APIC-EM from the 2960-x?
Are you using vlan1 for connection
Which interface on the switch is connected to the upstream network
Do you have a pre-defined rule for the device on APIC-EM, or are you using unclaimed device workflow?
