In the process of setting up APIC-EM and are testing the PnP feature. Currently have a c2960+24tc-l running 15.2(2)E setup on the test bench plugged into a DHCP port. After boot it reaches APIC-EM and is listed as an "unclaimed" device". When tried to claim it and push a new IOS image the following error occurs:
The switch is currently running 15.2(2)E and we are deploying 15.2(2)E3
12.2(2)E3 is the min supported version in the release notes.
Verify the time it takes to download the image to the 2960x. you need to be running 15.2(2)E3 as that is the first version that is supported.
Manually installed 15.2(2)E3 and then had APIC-EM push 15.2(2)E5. This succeeded. So this must be a version issue. Might have to try the image push via prime then.
IOS version 15.2(5)E is supported. 15.2(5) will not mention PnP as it had been added in earlier releases. Need to get 15.2(5) added.
