packets to on a particular interface. You can add up to five DHCP servers on each device
interface that the DHCP Relay Agent is listening on.
The no variant of this command deletes the specified DHCP server from the list of servers
available to the DHCP relay agent.
For DHCP Relay Agent introductory information, see
“DHCP Relay Agent Introduction”
