Is it possible to configure PowerConnect switches, so that they authenticate devices on a critical VLAN, if there is no connection to the RADIUS server ?
By critical VLAN, I mean corporate access VLAN, and not a guest VLAN. I know #dot1x unauth-vlan 20 or something similar can be used, but I intend to use that for guest access when the RADIUS is working. Basically, I want unauthenticated devices to be placed in different VLANs, depending if the RADIUS is up or down.
