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 per the ip helper-address
configuration. This occurs regardless if 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.
