Default interface reset issue after ISE configuration

Unanswered Question

Hi,

We're testing VOIP phones with ISE. ISE detects the phones by MAB and places them in our Voice VLAN with a DACL for security, this works fine.

After the tests I configured the port to a non ISE port (default interface) and added the normal working configuration.

Result is that the IP phone doesn't get an IP address. If I plug the same phone on a different interface on the same switch it's working again.

I have no idea why this strange behavior occurs, maybe someone can help me out.

 

Thanks, Michael

A reboot solves the problem temporary, so it looks like the running switch holds back some old configuration until a reboot
