Dynamic ARP Inspection Statistics

Field	Description
VLAN ID	The DAI-enabled VLAN associated with the rest of the information in the row. When DAI is enabled on a VLAN, DAI is enabled on all interfaces that are members of that VLAN.
DHCP Drops	The number of ARP packets that have been dropped by DAI because no matching DHCP (Dynamic Host Configuration Protocol) snooping binding entry was found in the DHCP snooping database.
ACL Drops	The number of ARP packets that have been dropped by DAI because the sender IP address and sender MAC address in the ARP packet did not match any rules in the ARP ACL (Access Control List) associated with this VLAN. The static flag on this VLAN is enabled, which means ARP packets that fail to match an ARP ACL rule are dropped immediately and are not checked against the DHCP snooping database for further validation.
DHCP Permits	The number of ARP packets that were forwarded by DAI because a matching DHCP snooping binding entry was found in the DHCP snooping database.
ACL Permits	The number of ARP packets that were forwarded by DAI because the sender IP address and sender MAC address in the ARP packet matched a rule in the ARP ACL associated with this VLAN.
Bad Source MAC	The number of ARP packets that were dropped by DAI because the sender MAC address in ARP packet did not match the source MAC address in the Ethernet header.
Bad Dest MAC	The number of ARP packets that were dropped by DAI because the target MAC address in the ARP reply packet did not match the destination MAC address in the Ethernet header.
Invalid IP	The number of ARP packets that were dropped by DAI because the sender IP address in the ARP packet or target IP address in the ARP reply packet was invalid. The following IP addresses are considered invalid: 0.0.0.0 255.255.255.255 All IP multicast addresses All class E addresses (240.0.0.0/4) Loopback addresses (in the range 127.0.0.0/8)
Forwarded	The total number of valid ARP packets forwarded by DAI.
Dropped	The total number of invalid ARP packets dropped by DAI.
