If the log buffer overflows, it means that a log event does not fit into the log buffer, and the output display

for the show ip arp inspection log privileged EXEC command is affected. A -- in the output 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.

This example shows how to configure the logging buffer to hold up to 45 entries:

Switch(config)# ip arp inspection log-buffer entries 45

This example shows how to configure the logging rate to 20 log entries per 4 seconds. With this

configuration, the switch generates system messages for five entries every second while there are entries

in the log buffer.

Switch(config)# ip arp inspection log-buffer logs 20 interval 4

You can verify your settings by entering the show ip arp inspection log privileged EXEC command.
