Command History Related Commands Version 8.3.16.1 debug ip udp-helper show ip udp-helper Introduced on MXL 10/40GbE Switch IO Module Enables debug and display the debug information on a console. Displays the configured UDP helper(s) on all interfaces. ip udp-helper udp-port Enable the UDP broadcast feature on an interface either for all UDP ports or a specified list of UDP ports. Syntax ip udp-helper udp-port [udp-port-list] To disable the UDP broadcast on a port, use the no ip udp-helper udp-port [udp-port-list] command. 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 none Command Modes INTERFACE (config-if) 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.
