Monitoring DAI
To monitor DAI, use the following commands:
DescriptionCommand
Clears dynamic ARP inspection statistics.clear ip arp inspection statistics
Displays statistics for forwarded, dropped, MAC
validation failure, IP validation failure, ACL permitted
and denied, and DHCP permitted and denied packets
for the specified VLAN. If no VLANs are specified
or if a range is specified, displays information only
for VLANs with dynamic ARP inspection enabled
(active).
show ip arp inspection statistics [vlan vlan-range]
Clears the dynamic ARP inspection log buffer.clear ip arp inspection log
Displays the configuration and contents of the
dynamic ARP inspection log buffer.
show ip arp inspection log
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.
