The set protocols arp inspection vlan disable command enables or disables ARP inspection in a VLAN.

Command Syntax

set protocols arp inspection vlan <vlan-id> disable <true | false>




vlan <vlan-id>

Specifies a VLAN. The value is an integer that ranges from 1 to 4094.

disable <true | false>

Enables or disables the ARP inspection. The value could be true or false.

  • true: disables the ARP inspection function.
  • false: enables the ARP inspection function.

By default, ARP inspection function is disabled.

Usage Guidelines

When ARP inspection is enabled in a VLAN, the device checks ARP packets received on interfaces belong to the VLAN based on the static access lists (if configured) and the DHCP binding table except when the interface is a trust port (configured by using command set protocols arp inspection trust-port <port-name>).


Regardless of the fact that whether its static access lists or dynamic ARP inspection, you have to explicitly enable the ARP inspection function in the VLAN by using this command.
