Figure 8. Example of an Active VLAN Configuration
In Figure Figure 8, if RADIUS authorizes an 802.1X client on port A2 with the requirement that the
client use VLAN 22, then:
■ VLAN 22 becomes available as Untagged on port A2 for the duration of the session.
■ VLAN 33 becomes unavailable to port A2 for the duration of the session (because there can be
only one untagged VLAN on any port).
To view the temporary VLAN assignment as a change in the active configuration, use the show vlan
<vlan-id> command as shown in Figure Figure 9, where <vlan-id> is the (static or dynamic) VLAN used
in the authenticated client session.
Figure 9. Active Configuration for VLAN 22 Temporarily Changes for the 802.1X Session
However, as shown in Figure Figure 8, because VLAN 33 is configured as untagged on port A2 and
because a port can be untagged on only one VLAN, port A2 loses access to VLAN 33 for the duration
of the 802.1X session on VLAN 22.
You can verify the temporary loss of access to VLAN 33 by entering the show vlan 33 command as
shown in Figure Figure 10.
