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


Command Syntax

Parameters

Parameter

Description

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>).

NOTE:

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.


Example

  • Enable ARP inspection in VLAN 100.
admin@XorPlus# admin@Xorplus# set protocols arp inspection vlan 100 disable false
admin@XorPlus# commit
