ip dhcp relay information trusted

with giaddr==0 (this relay agent is the first relay of this DHCP request packet)

and relay agent information option is already present in the packet. Use the no

Usage Guideline When IP DHCP relay information is trusted, if the gateway address in the DHCP

request packet is set to all zeros but the relay agent information option is already

present in the packet, the DHCP relay agent will accept the packet.

If it is un-trusted, then the packet will be discarded.

Example This example shows how to enabled interface vlan100's DHCP relay agent to

accept the packets with giaddr==0 and relay agent information option is already

present in the packet.

Verify the settings by entering the show ip dhcp relay information trusted-

sources command.

Swtich(config-if)# end
