When the 802.1X client session on port A2 ends, the port removes the temporary untagged VLAN
membership. The static VLAN (VLAN 33) that is "permanently" configured as untagged on the

port A2 ends, VLAN 22 access on port A2 also ends, and the untagged VLAN 33 access on port
A2 is restored as shown in Figure
