Configuring Port-Based and User-Based Access Control (802.1X)

How RADIUS/802.1X Authentication Affects VLAN Operation

This entry shows that port A2 is temporarily untagged on

VLAN 22 for an 802.1X session. This is to accommodate

an 802.1X client’s access, authenticated by a RADIUS

server, where the server included an instruction to put

the client’s access on VLAN 22.

Note: With the current VLAN configuration (figure 12-19),

the only time port A2 appears in this show vlan 22 listing

is during an 802.1X session with an attached client.

Otherwise, port A2 is not listed.

Figure 12-20. The Active Configuration for VLAN 22 Temporarily Changes for the 802.1X Session

However, as shown in Figure 12-19, 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 12-21.

Even though port A2 is

configured as Untagged

on (static) VLAN 33 (see

figure 12-19), it does not

appear in the VLAN 33

listing while the 802.1X

session is using VLAN 22

in the Untagged status.

However, after the 802.1X

session with VLAN 22

ends, the active

configuration returns port

A2 to VLAN 33.
