Use this command to set a port as a trusted port. The DHCP response messages received under the
trust port are forwarded normally, but the response messages received under the untrusted port will
be discarded. This command is only supported on Layer 2 switch interfaces and aggregate ports
(APs).
The following example sets fastEthernet 0/1 as a trusted port:
Ruijie# configure terminal
Ruijie(config)# interface fastEthernet 0/1
Ruijie(config-if)# ip dhcp snooping trust
Ruijie(config-if)# end
