PnP Protocol

Hello Experts,

I was trying to provision an ASR901 and ME3600 devices via APIC-EM PnP.

Now, I do know that both are not officially supported (https://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Plug-and-Play/release/notes/pnp-release-notes15.pdf) but since both have the pnp protocol support, i thoutht that it might work.

Well, it did not

The ME-3600 reached the DHCP server, pulled an IP address but was not directed to the controller, instead, it was trying to poll the configuration from the DHCP (yes, I saw many threads about that issue... - see CLI output below)

The ASR901 didnt even reach the DHCP. In addition, creating manually pap profile (following Adam's advice - Design Recommendation for APIC-EM Network | Cisco Communities) didn't help (found several pap errors post reload)

So my questions are:

  1. What's the different between APIC-EM / supported devices PnP protocol support vs. other device w/ PnP protocol support as well? Is it the PNP protocol version?
  2. Is there any procedure how APIC-EM can be used w/ older type of devices (which supported PnP as well) for example, ASR901, ASR903, Cisco 7600?

Thanks!

We have evolved the PnP protocol quite a lot over the last 2 years.

Older products that are not officially supported will not have these enhancements.

There are some interesting interactions with Vlans, etherchannels, DHCP startup, certificates etc, bootstrap configs etc.  We have also added capabilities like PnP Connect (cloud redirect) and trust-bundle verification.

The best way to get PnP support is to make a request from the product management team for the platform.

I would not recommend using older unsupported versions as you will definitely find issues.
