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.
