This is our bug registered by Cisco TAC.
Use case: ISE 2,4 Patch 5 and HP printer connected to switchport with MAB configured on it.
When device switches to hibernate state, radius live log collects a lot of repeated DALC events that not suppressed by ISE. At this time switchport is flapping from up to down until the printer wakes up.
Does anyone have faced with this kind of issues?
Here is a MAB template for switchport:
authentication control-direction in
authentication port-control auto
authentication periodic
authentication host-mode single-host
authentication timer reauthenticate server
authentication timer inactivity server
mab
