KB.15.15

port-based, untagged VLAN membership assigned for the earliest, currently active client

session.

Therefore, on a port where one or more authenticated client sessions are already running, all

such clients are on the same untagged VLAN. If a RADIUS server subsequently authenticates

a new client, but attempts to re-assign the port to a different, untagged VLAN than the one

already in use for the previously existing, authenticated client sessions, the connection for the

new client will fail.
