Dynamic ARP Inspection Commands

Dynamic ARP Inspection (DAI) is a security feature that rejects invalid and 
malicious ARP packets. DAI prevents a class of man-in-the-middle attacks, 
where an unfriendly station intercepts traffic for other stations by poisoning the 
ARP caches of its unsuspecting neighbors. The miscreant sends ARP requests or 
responses mapping another station’s IP address to its own MAC address.

DAI relies on DHCP snooping. DHCP snooping listens to DHCP message 
exchanges and builds a binding database of valid 

{

MAC address, IP address, 

VLAN, and interface

}

 tuples.

When DAI is enabled, the switch drops ARP packets whose sender MAC address 
and sender IP address do not match an entry in the DHCP snooping bindings 
database. You can optionally configure additional ARP packet validation.

ip arp inspection 
vlan

Use this command to enable Dynamic ARP Inspection on a list of comma-
separated VLAN ranges.

no ip arp inspection 
vlan

Use this command to disable Dynamic ARP Inspection on a list of comma-
separated VLAN ranges.

ip arp inspection 
validate

Use this command to enable additional validation checks like source-mac 
validation, destination-mac validation, and ip address validation on the received 
ARP packets. Each command overrides the configuration of the previous 
command. For example, if a command enables src-mac and dst-mac validations, 
and a second command enables IP validation only, the src-mac and dst-mac 
validations are disabled as a result of the second command.
