We have dot1x enabled with MDA. Consider this scenario:
Only one Cisco IP phone is connected to the switchport (no PC). And phone fails both dot1x and MAB. Switch will place it in DATA vlan by default. This works as expected....Why doesn't IP phone work while in DATA vlan? It keeps showing "registering", "configuring IP" etc. IP helpers are same for both data and voice vlan.
If the phone has passed authentication and authorization succesfully then it's a connectivity issue. The ip phone keeps saying "registering" because it can't reach the Call Manager. Could you please check connectivity ?
