Odd issue with a Cisco phone.

I don't think this is an ISE issue, but wanted to ask in case I'm missing something.

So, we are changing over from an Avaya to Cisco phone system using ISE for authentication to the network.

So far all is going well until we tried a CP-8832 conference phone. The issue I am having is it is retrying 802.1x over and over without success. But, I have other models on the same switch that have worked fine.

What's really odd is the phone works at the facility here, but fails at our remote facility. We send a second down and that one doesn't work either.

This is the debug on the switch. Has anyone had a similar issue they were able to fix?

Dustin,

802.1x is getting stuck there. I checked the datasheet and it mentioned 802.1x.

If other models are working except for this, try upgrading the software and see if it resolves it.

You can reset/reboot the phone and take a debug as well. Not sure what is going on there.
