IP Addressing Commands

167

ip helper-address

Use the Global Configuration ip helper-address command to have the device 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.

ip helper-address ip-interface address [udp-port-list]

no ip helper-address ip-interface address

Syntax Description

ip-interface

- Specify IP interface or all.

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.

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.

Default Configuration

Disabled

Command Mode

Global Configuration

User Guidelines

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 helper address for specific interface has precedence over a setting of helper address 
for all the interfaces.

You can’t enable forwarding of BOOTP/DHCP (ports 67,68) with this command. If you want to 
relay BOOTP/DHCP packets use the DHCP relay commands. 

The 

ip helper-address 

command specifies a UDP port number for which UDP broadcast packets 

with that destination port number are forwarded. By default, if no UDP port number is specified, 
the device forwards UDP broadcast packets for the following six services:

•

IEN-116 Name Service (port 42) 

•

DNS (port 53)

•

NetBIOS Name Server (port 137)

•

NetBIOS Datagram Server (port 138)

•

TACACS Server (port 49)

•

Time Service (port 37)
