The dhcp trust port command configures a DHCP trusted interface on an RU.

The undo dhcp trust port command cancels the configuration.

By default, the DHCP trusted interface is enabled on an AP.

Usage Guidelines

Usage Scenario

Before WLAN services are delivered to an RU, run the dhcp trust port command in the AP wired port profile view. After the command is run, the RU receives the DHCP OFFER, ACK, and NAK packets sent by the authorized DHCP server and forwards the packets to STAs so that the STAs can obtain valid IP addresses and go online.


When executed in the AP wired port, this command takes effect only on uplink interfaces of an RU. To configure a downlink wired interface on an RU as a DHCP trusted interface, you only need to run the learn-client-address (AP wired port profile view) command to enable STA address learning, but do not need to run the dhcp trust port command.


# Create an AP wired port profile named wire1, and enable a DHCP trusted interface on an RU in this profile.
