Command Line Interface Reference for the ProSafe 7300S Series Layer-3 Stackable Switches, 19.1 UDP Relay Configuration Commands This section describes configuration commands for setting up UDP relay service. 19.1.1 ip helper-address (global config mode) Use the Global Configuration ip helper-address command to have the switch forward User Datagram Protocol (UDP) broadcasts received on an interface. To disable the forwarding of broadcast packets to specific addresses, use the no form of this command. The ip helper-address command forwards specific UDP broadcast from one interface to another. You can define many helper addresses but the total number of address-port pairs is limited to 128 for the whole device. The setting of a helper address for a specific interface has precedence over a setting of a helper address for all interfaces. You cannot enable forwarding of BOOTP/DHCP packets (ports 67,68) with this command. If you want to relay BOOTP/DHCP packets, use the DHCP relay commands. Format ip helper-address {intf-address | all} ip-address [udpport-list] no ip helper-address {intf-address | all} ip-address Parameters Mode Default intf-address IP address of a routing interface. all Indicates that this UDP port to address mapping should be used for all IPv4 routing interfaces. The exception is if a particular routing interface has its own mapping; then that mapping takes precedence. Ip-address Destination broadcast or host address to be used when forwarding UDP broadcasts. You can specify 0.0.0.0 to indicate not to forward the UDP packet to any host and use "255.255.255.255" to broadcast the UDP packets to all hosts on the target subnet. udp-port-list The broadcast packet destination UDP port number to forward. If not specified, packets for the default services are forwarded to the helper address. Valid range, 065535. Global Config Disabled 19-2 v3.0, January 2008 UDP Relay Commands
