Usage Guidelines The first dropped packet of a given flow is logged immediately. The subsequent packets for the same
flow are registered but are not logged immediately. Registering these packets is done in a log buffer that
is shared by all the VLANs. Entries from this buffer are logged on a rate-controlled basis.
Examples This example shows how to configure the logging buffer to hold up to 45 entries:
Switch# config terminal
Enter configuration commands, one per line.
Switch(config)# ip arp inspection log-buffer entries 45
Switch(config)# end
Switch# show ip arp inspection log
Total Log Buffer Size : 45
Syslog rate : 5 entries per 1 seconds.
No entries in log buffer.
