DESCRIPTION
Active
Select this to enable ARP inspection on the OLT. 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 OLT after the
OLT identifies an unauthorized ARP packet. The OLT 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 OLT exceeds this number, the OLT 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
