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.
