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
26.9 on page 238.
