No. Items to check and commands Action
2 VLAN interface setting [Fixed VLAN mode]
Make sure the IP address for the VLAN interface is set correctly.
[Dynamic VLAN mode] [Legacy mode]
Make sure the IP addresses for the following VLAN interfaces are set
correctly:
 Pre-authentication VLAN
 Post-authentication VLAN
3 Check the filtering configuration. Certain packets might have been discarded by filtering or packets
might have been discarded by the shaper of QoS control. Make sure
that the setting conditions for filtering and QoS control in the
configuration are correct, and that the shaper is used appropriately in
the system configuration. For details about the procedure, see
3.13.1
Checking the filtering and QoS control configuration information.
4 Setting the authentication IPv4
access list
[Fixed VLAN mode] [Dynamic VLAN mode]
Make sure that the filtering conditions required for communication
from unauthenticated terminals to destinations outside the Switch
have been set correctly by using the authentication ip
access-group and ip access-list extended configuration
commands.
5 Setting of ARP packet forwarding [Fixed VLAN mode] [Dynamic VLAN mode]
Make sure that the authentication arp-relay configuration
command is set correctly so that unauthenticated terminals can send
ARP packets to devices outside the Switch.
3.7.4 Communication failures occurring when secure Wake-on-LAN is used
[OP-WOL]
If a failure occurs when secure Wake-on-LAN.1X is used, isolate the cause of the problem
according to the failure analysis method described in the table below.
 Internal DB for registering the terminal that sends the startup command: WOL
terminal DB
 Internal DB for user authentication: WOL user DB
Table 3-31 Failure analysis method for secure Wake-on-LAN
No. Items to check and commands Action
1 Check whether the user
authentication page for secure
Wake-on-LAN appears on the
terminal.
If the user authentication page does not appear, continue with No. 2.
If the user authentication page appears:
 If user authentication is not possible, continue with No. 3.
 If user authentication is possible:
If Not available appears on the page used for selecting the
terminal and sending the startup command, continue with
No. 5.
If startup of the terminal cannot be confirmed after the startup
command is sent, continue with No. 6.
