ip arp inspection log-buffer
In a switch stack, the log buffer configuration applies to each stack member in the stack. Each stack
member has the specified logs number entries and generates system messages at the configured rate. For
example, if the interval (rate) is one entry per second, up to five system messages are generated per
second in a five-member switch stack.
Examples 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.
