3.3.4 Verifying Configuration
To verify that the configuration of Guest VLAN is taking effect, check that users can
access VLAN 10 before 802.1x authentication or the 802.1x authentication fails.
To verify that the dynamically assigned VLAN is taking effect, check that users can
access VLAN 100 after 802.1x authentication succeeds. At the same time, 802.1x
authentication cooperates with CAMS to complete accounting and real time monitoring.
To verify that the configuration of IP-to-MAC binding is taking effect, check that users
can be re-authenticated and access the Internet when the device reboots abnormally. If
the configured IP-to-MAC binding is different from that on the CAMS, the user cannot
access the Internet.
3.3.5 Troubleshooting
I. Symptom: 802.1x authentication failed
Solution:
z
Use the
display dot1x
command to verify 802.1x is enabled globally and on the
specified ports.
z
Verify the username and password are set correctly.
z
Verify the connection works well.
z
Use the
debugging dot1x packet
command to verify the switch receives and
sends EAP and EAPoL packets normally.
