3.Troubleshooting Functional Failures in Operation

No.	Check Point	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."
