Description
Override the DHCP relay agent information option (option 82) in DHCP packets destined for a DHCP server. Using this option allows the DHCP relay agent to perform one of the following actions, depending on the configuration:
If the DHCP relay agent is configured to add option 82 information to the DHCP packets, the DHCP relay agent clears the existing option 82 values from the DHCP packets and inserts the new values before forwarding the packets to the DHCP server.
If the DHCP relay agent is not configured to add option 82 information to DHCP packets, the DHCP relay agent clears the existing option 82 values from the packets, but does not add any new values before forwarding the packets to the DHCP server.
