Web authentication

The login failed because of hardware restriction.

 

(Static VLAN mode)

Note: This log is displayed when the show web-authentication logging

 

 

command is executed.

is executed.

 

 

 

* The log message of No. 1 may be output at the same time.

If these log messages are output, the function that newly uses the MAC address table cannot be set. Review the network configuration and set the configuration allowing for operation below the limit of the system's accommodating condition.

No. 2, 3, 4 and 6 in the above table shows that setting cannot be registered to the MAC address table by the configuration command. No. 5 shows that setting cannot be registered to the MAC address table of the authenticated terminal (authentication failed). For re-configuration, follow the steps below.

1.Review that configuration so that new entries will not be registered by MAC address learning, ARP/NDP learning, and IEEE802.1X authentication when a free space is provided in the MAC address table.

2.Clear the executed command (for No. 2, 3, 4 and 6 in the above table).

3.Make a free space in the MAC address table.*

4.Re-execute the command (for No. 2, 3, 4 and 6 in the above table) or re-authenticate (for No. 5).

*To provide a free space in the MAC address table, registered entries must be cleared. The clear procedure for each entry is shown in the table below.
