Command Line Interface Reference for the ProSafe 7300S Series Layer-3 Stackable Switches, 19.1.2 ip helper-address (interface config mode) The ip helper-address interface configuration command enables forwarding User Datagram Protocol (UDP) Broadcast packets received on an interface. Many helper addresses can be defined. The maximum number of address-port pairs is up to 128 for the whole device. The helper-address interface configuration command forwards a specific UDP Broadcast from one interface to another. The helper-address interface configuration command specifies a UDP port number for which UDP Broadcast packets with that destination port number are forwarded. The helper-address interface configuration command does not enable forwarding of BOOTP/DHCP packets. To forward BOOTP/DHCP packets, use the bootpdhcprelay enable and bootpdhcprelay serverip global configuration commands and the show bootpdhcprelay privileged EXEC command. To disable forwarding Broadcast packets to specific addresses, use the no form of this command. Format ip helper-address ip-address [udp-port-list] no ip helper-address ip-address Parameters 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.

ip helper-address (interface config mode)
The
ip
helper-address
interface configuration command enables forwarding User
Datagram Protocol (UDP) Broadcast packets received on an interface.
Many helper addresses can be defined. The maximum number of address-port pairs is up
to 128 for the whole device. The
helper-address
interface configuration command
forwards a specific UDP Broadcast from one interface to another. The
helper-address
interface configuration command specifies a UDP port number for which UDP Broadcast
packets with that destination port number are forwarded. The
helper-address
interface
configuration command does not enable forwarding of BOOTP/DHCP packets. To
forward BOOTP/DHCP packets, use the
bootpdhcprelay enable
and
bootpdhcprelay
serverip
global configuration commands and the
show bootpdhcprelay
privileged EXEC
command.
To disable forwarding Broadcast packets to specific addresses, use the no form of this
command.

Parameters
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.

The broadcast packet destination UDP port
number to forward. If not specified, packets for the default
services are forwarded to the helper address.
