Usage
Information
If you configure the ip helper-address command and ip udp-helper udp-port command, the behavior
is that the UDP broadcast traffic with port numbers 67/68 is unicast relayed to the DHCP server as per
the ip helper-address configuration. This occurs regardless of whether the ip udp-helper udp-port
command contains port numbers 67/68 or not.
If you only configure the ip udp-helper udp-port command, all the UDP broadcast traffic is flooded,
including ports 67/68 traffic if those ports are part of the udp-port-list.
