Troubleshooting Steps

 

 

 

3

Setting of DHCP relay agent

Confirm that the following inter-VLAN DHCP relay agent is set

 

 

correctly:

 

 

• Between pre-authentication VLAN and authentication server VLAN

 

 

• Between post-authentication VLAN and authentication server

 

 

VLAN

 

 

 

4

Filter setting

Confirm that the following inter-VLAN filter is set correctly:

 

 

• Between pre-authentication VLAN and post-authentication VLAN:

 

 

Set the filter to disable all IP communications.

 

 

• Between pre-authentication VLAN and authentication server

 

 

VLAN: Set the filter to relay the HTTP, DHCP, and ICMP

 

 

communications only.

 

 

• Between pre-authentication VLAN and VLAN to access: Set the

 

 

filer to disable all IP communications.

 

 

• Between post-authentication VLAN and authentication server

 

 

VLAN: Set the filter to relay the HTTP, DHCP, and ICMP

 

 

communications only.

 

 

• Between authentication server VLAN and VLAN to access: Set the

 

 

filter to disable all IP communications.

 

 

Certain packets may have been discarded by filtering, or packets may

 

 

have been discarded through bandwidth monitoring, discarding control,

 

 

or shaper of the QoS control. Check to see if the conditions of filtering

 

 

and QoS control in the configuration have been set up correctly and if

 

 

bandwidth monitoring, discarding control, or shaper has been set up

 

 

appropriately for system operation. For the procedure, see

 

 

"3.23.1 Checking Filtering/QoS Setting Information."
