LAN Automation keeps failing

Hi,

 

I am trying to LAN automate some Fabric Edge switches in my setup. But every time I start the LAN Automation it keeps staying in the Initialized state.

The VLAN1 is pushed to the Primary device.

PNP Agents get an IP, and option 43.

PNP Agents contact the PNP Server on http and changes to https. But it seems like there are no jobs for the PNP Agent.

 
 
 

And then it stops at:

*Oct 19 14:40:51.718: %AN-6-AN_ABORTED_BY_CONSOLE_INPUT: Autonomic disabled due to User intervention on console. configure 'autonomic' to enable it.

Any help on troubleshooting is appreciated. I have done some PCAPs of the traffic but nothing I can figure out.

I have seen similar issues in the past which was due to option43 being misconfigured.  I would start with ensuring it is configured properly and re-test.  Also, verify that proper path/ports are available/allowed.  Here are the specifications for option43:

5A1N - specifies plug and play
B2 - ipv4 type
I10.X.X.X - connect to dnac ip
J443 - port # to use

For additional assistance see here: https://www.cisco.com/c/en/us/support/docs/cloud-systems-management/dna-center/215336-lan-automation-step-by-step-deployment.html

This is also a good blog series: https://blogs.cisco.com/developer/cisco-dna-center-plug-and-play-pnp-part-1

HTH!

This is configured correctly. And a monitor capture shows the PNPAgents connecting to the DNAC on port 80.

Make sure correct license is installed (Network Advantage) and “ip routing” is enabled on Seed device!

Check out page no 33 on below link 

https://www.ciscolive.com/c/dam/r/ciscolive/emea/docs/2019/pdf/BRKSDN-2500.pdf

 

My NA license has expired on the Seed device.

but IP Routing is enabled.
