Dell Force10 E300, Configuration Manual, Page: 120 / 1262

120 | 802.1X
www.dell.com | support.dell.com
Figure 7-11 shows the configuration on a Dell Force10 switch that uses dynamic VLAN assignment with
802.1X before you connect the end-user device (black and blue text), and after you connect the device (red
text).
The blue text corresponds to the numbered steps on page 119. Note that the GigabitEthernet 1/11 port, on
which dynamic VLAN assignment with 802.1X is configured, is initially an untagged member of VLAN
300. After a successful 802.1x authentication with dynamic VLAN configuration, the port becomes an
untagged member of VLAN 400 (assigned by the RADIUS server during authentication).
Figure 7-11. Dynamic VLAN Assignment with 802.1X
Note: In the
show vlan
command output, if the statically-configured VLAN and the 802.1X
dynamically-assigned VLAN are the same, the 802.1x-authorized port is displayed with
U
for
Untagged
.
If the two VLANs are not the same, the 802.1x-authorized port is displayed with
x
for
Dot1X untagged
.
