Dynamic ARP Inspection Overview

Basic Configuration

The following basic configuration does not change the default rate limiting parameters.

Procedure 17-2 Basic Dynamic ARP Inspection Configuration

Step	Task	Command(s)

1.	Configure DHCP snooping.	Refer to Procedure 17-1on page 17-3.

2.	Enable ARP inspection on the VLANs where	set arpinspection vlan vlan-range
	clients are connected, and optionally, enable	[logging]
	logging of invalid ARP packets.

3.	Determine which ports are not security threats	set arpinspection trust port
	and configure them as DAI trusted ports.	port-string enable
4.	If desired, configure optional validation	set arpinspection validate
	parameters.	{[src-mac][dst-mac] [ip]}
5.	If desired, configure static mappings for DAI by	set arpinspection filter name permit
	creating ARP ACLs:	ip host sender-ipaddrmac host
	• Create the ARP ACL	sender-macaddr
	• Create the ARP ACL	set arpinspection filter name vlan
	• Apply the ACL to a VLAN	set arpinspection filter name vlan
		vlan-range [static]
