If the log buffer overflows, it means that a log event does not fit into the log buffer, and the display for
the show ip arp inspection log privileged EXEC command is affected. A -- in the display appears in
place of all data except the packet count and the time. No other statistics are provided for the entry. If
you see this entry in the display, increase the number of entries in the log buffer, or increase the logging
rate in the ip arp inspection log-buffer global configuration command.

For the show ip arp inspection statistics command, the switch increments the number of forwarded
packets for each ARP request and response packet on a trusted dynamic ARP inspection port. The switch
increments the number of ACL or DHCP permitted packets for each packet that is denied by source
MAC, destination MAC, or IP validation checks, and the switch increments the appropriate failure count.
