Known Affected Releases

15.4(99.99)

Description (partial)

Symptom:
After dot1x commands are applied and the switch is rebooted, following commands are applied to each and every port:
Authentication port-control auto
Authentication open
So if it's a layer 3 interface, it changes it to a switchport and kills the layer 3 interface/uplink. This happens also when applying standard 802.1x template manually.

Conditions:
Customer using dot1x template on 2520 running code 15.2(4)EA9.
