Description
Forward specified DHCP client packets, without creating a new subscriber session, when you use DHCP relay selective processing feature. You can configure the forwarding operation globally or for a group of interfaces, and for either DHCP or DHCPv6 relay agent. Use this command to manage subscribers, when large number of DHCP relay requests are received and license limitations are exceeded. This command uses option 82 and applies "scale-subscriber" license.
DHCP packets forwarded with the forward-only statement do not
consider other configurations except for the
trust-option-82
option. The DHCP relay agent ignores all other configured options.
