ip dhcp relay information policy

Use this command to configure the information re-forwarding policy for the DHCP

relay agent.

ip dhcp relay information policy {drop | keep | replace}

Default replace.

Command Mode Global configuration.

Usage Guideline The device may receive a DHCP request packet that already has the relay

option. This packet represents a packet that is relayed by a relay agent and

already has the option inserted. The gateway address in the received DHCP

packet should not be zero since it represents the IP address of the predecessor

DHCP relay agent.

Example This example shows how to set the policy to drop the DHCP request packet that

is relayed by other DHCP relay agent and already has option-82 inserted.

Verify the settings by entering the show ip dhcp relay command.

Syntax Description

drop Discards the packet that already has the relay option. This packet represents a

packet that is relayed by a relay agent and already has the option inserted.

keep When the DHCP request packets already have the relay option, then the relay

option is left unchanged and directly relayed to the DHCP server.

replace When the DHCP request packets already have the relay option, then it will be

replaced by a new option.
