Interface configuration mode
If it is necessary to make the ARP message received by some interface pass the DAI inspection
unconditionally, you can set the interface to a trusted port, indicating that you do not need to check
whether the ARP message received by this interface is legal.
The following example sets the gigabitEthernet 0/19 interface as the trusted port.
Ruijie# configure terminal
Ruijie(config)# interface gigabitEthernet 0/19
Ruijie(config-if-GigabitEthernet 0/19)# ip arp inspection trust
Ruijie(config-if-GigabitEthernet 0/19)# end
show ip arp inspection interface
Displays related DAI information on the
interface, including the trust state and rate limit
of the interface.
17.2 ip arp inspection vlan
Use this command to configure the DAI function on the VLAN.
Use the no form of this command to disable this function.
