Table 90 ARP Inspection Configure

LABEL	DESCRIPTION
Active	Select this to enable ARP inspection on the Switch. You still have
	to enable ARP inspection on specific VLAN and specify trusted
	ports.

Filter Aging Time

Filter aging time	This setting has no effect on existing MAC address filters.
	Enter how long (1~2147483647 seconds) the MAC address filter
	remains in the Switch after the Switch identifies an unauthorized
	ARP packet. The Switch automatically deletes the MAC address
	filter afterwards. Enter 0 if you want the MAC address filter to be
	permanent.

Log Profile

Log buffer size	Enter the maximum number (1~1024) of log messages that were
	generated by ARP packets and have not been sent to the syslog
	server yet. Make sure this number is appropriate for the specified
	Syslog rate and Log interval.
	If the number of log messages in the Switch exceeds this number,
	the Switch stops recording log messages and simply starts
	counting the number of entries that were dropped due to
	unavailable buffer. Click Clearing log status table in the ARP
	Inspection Log Status screen to clear the log and reset this
	counter. See Section 26.6.2 on page 287.
