52.4 802.1x Troubleshooting
It is possible that 802.1x be configured on ports and 802.1x authentication be set to auto, t switch can’t be to
authenticated state after the user runs 802.1x supplicant software. Here are some possible causes and
solutions:
 If 802.1x cannot be enabled for a port, make sure the port is not executing MAC binding, or
configured as a port aggregation. To enable the 802.1x authentication, the above functions must be
disabled.
 If the switch is configured properly but still cannot pass through authentication, connectivity
between the switch and RADIUS server, the switch and 802.1x client should be verified, and the
port and VLAN configuration for the switch should be checked, too.
 Check the event log in the RADIUS server for possible causes. In the event log, not only
unsuccessful logins are recorded, but prompts for the causes of unsuccessful login. If the event log
indicates wrong authenticator password, radius-server key parameter shall be modified; if the event
log indicates no such authenticator, the authenticator needs to be added to the RADIUS server; if
the event log indicates no such login user, the user login ID and password may be wrong and
should be verified and input again.
