Chapter 26 IP Source Guard 26.7 ARP Inspection Configure Use this screen to enable ARP inspection on the Switch. You can also configure the length of time the Switch stores records of discarded ARP packets and global settings for the ARP inspection log. To open this screen, click Advanced Application > IP Source Guard > ARP Inspection > Configure. Figure 158 ARP Inspection Configure The following table describes the labels in this screen. Table 119 ARP Inspection Configure LABEL Active Filter Aging Time Filter aging time Log Profile Log buffer size 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 Section 26.6.2 on page 264. VES1724-56 User's Guide 265
