If these log messages are output, the function that newly uses the VLAN identification 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. 1, 2, and 3 in the above table show that setting cannot be registered to the VLAN identification table by the configuration command. No. 4 and 5 show that setting cannot be registered to the VLAN identification table. For re-setting, follow the steps below.

1.Review the configuration so that new entries will not be registered by IEEE802.1X authentication, Web authentication, and authentication VLAN when a free space is provided in the VLAN identification table.

2.Clear the executed command (for No. 1, 2, and 3 in the above table).

3.Make a free space in the VLAN identification table.*

4.Re-execute the command (for No. 1, 2, and 3 in the above table), or re-authenticate (for No. 4), or review the number of users to be authenticated by the authentication server (for No. 5).

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