DESCRIPTION
Select this to enable ARP inspection on the Switch. You still have to
enable ARP inspection on specific VLAN and specify trusted ports.
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.
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
page 229.
