LABEL DESCRIPTION
ARP Inspection Setup
Active Enable the switch button 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. Type 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 SECURITY > IPv4 Source Guard >
ARP Inspection > ARP Insp. Log Status screen to clear the log and reset this counter.
