Troubleshooting Functional Failures in Operation
Action
• If the authenticated MAC address is registered by the show vlan
mac-vlan command, authentication for the MAC address is not
enabled. Clear the MAC address registered by the command.
• If the MAC address authenticated for each VLAN is not displayed,
internal conflict has occurred. Restart the authentication VLAN
using the restart vaa command.
• If the authenticated MAC address is not displayed even though the
authentication VLAN is restarted, restart the L2MAC manager
program using the restart vlan command with "mac-manager"
parameter specified.
• Otherwise, go to No. 9.
• If the "The registration of the MAC address failed." log is output by
the show fense logging command, see
When VLAN Identification Table Resource Shortage
[IP8800/S6700] [IP8800/S6600] [IP8800/S6300]
Otherwise, check the configuration of the authentication VLAN.
