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.
This is an example of output from the show ip arp inspection statistics command. It shows the statistics
for packets that have been processed by dynamic ARP inspection for all active VLANs.
Switch# show ip arp inspection statistics
