Parameters udp-port-list (OPTIONAL) Enter up to 16 comma separated UDP port numbers. Note: If this option is not used, all UDP Ports are considered by default. Defaults No default behavior or values Command Modes INTERFACE (config-if) Usage Information If the ip helper-address command and ip udp-helper udp-port command are configured, the behavior is that the UDP broadcast traffic with port numbers 67/68 will be unicast relayed to the DHCP server per the ip helper-address configuration. This will occur regardless if the ip udp-helper udp-port command contains port numbers 67/68 or not. If only the ip udp-helper udp-port command is configured, all the UDP broadcast traffic is flooded, including ports 67/68 traffic if those ports are part of the udp-port-list.
