		set arpinspection trust
Parameters

	vlan‐range	Specifies the VLAN or range of VLANs on which to enable dynamic
		ARP inspection.

	logging	(Optional) Enables logging of invalid ARP packets for that VLAN.

Defaults

Logging is disabled by default.

Mode

Switch command, read‐write.

Usage

This command enables dynamic ARP inspection (DAI) on one or more VLANs. When DAI is enabled on a VLAN, DAI is effectively enabled on the interfaces (physical ports or LAGs) that are members of that VLAN.

DAI uses the DHCP snooping bindings database to verify that the sender MAC address and the source IP address are a valid pair in the database. ARP packets whose sender MAC address and sender IP address do not match an entry in the database are dropped.

If logging is enabled, invalid ARP packets are also logged.

Example

This example enables DAI on VLANs 2 through 5 and also enables logging of invalid ARP packets on those VLANs.

C3(su)->set arpinspection vlan 2-5 logging

set arpinspection trust

Use this command to enable or disable a port as a dynamic ARP inspection trusted port.

Syntax

set arpinspection trust port port-string{enable disable}

Parameters

port‐string	Specifies the port or ports to be enabled or disabled as DAI trusted
	ports. The ports can be physical ports or LAGs that are members of a
	VLAN.

enable disable	Enables or disables the specified ports as trusted for DAI.

Defaults

By default, all physical ports and LAGs are untrusted.

Mode

Switch command, read‐write.
