CLI Reference Guide
Use this global command to direct the DHCP relay agent to accept the packets
with giaddr==0 (this relay agent is the first relay of this DHCP request packet)
and the relay agent information option already present in the packet. Use the no
form of the command to specify to drop these DHCP request packets.
None
The interface default is un-trusted.
Global configuration
When the IP DHCP relay information is trusted, and the gateway address in the
DHCP request packet is set to all zeros, but the relay agent information option is
present in the packet, then the DHCP relay agent will accept the packet.
When the packet is not trusted, then it will be discarded.
This command is under global configuration; it will enable/disable all existing
VLANs' DHCP Relay Agent trusted relay agent information. However, the
command takes effect only in the running configuration and is not kept in NVRAM
for the next boot cycle using the startup configuration.
To configure a specific interface's trust status, use the ip dhcp relay information
trusted interface command.
This command shows how to enable all interfaces with the DHCP relay agent set
to accept the packets with giaddr==0 and the relay agent information option
already present in the packet.
Verify the settings by entering the show ip dhcp relay information trusted-
