35.14 ip helper-address

Use the ip helper-address Global Configuration mode command to enable the 
forwarding of User Datagram Protocol (UDP) broadcast packets received on an 
interface to a specific (helper) address. Use the no form of this command to 
disable the forwarding of broadcast packets to a specific (helper) address.

Syntax

ip helper-address {

ip-interface | all}

 

address

 [

udp-port-list

]

no ip helper-address {

ip-interface | all}

 

address

Parameters

•

ip-interface—Specifies the IP interface.

•

all—Specifies all IP interfaces.

•

address—Specifies the destination broadcast or host address to which to 
forward UDP broadcast packets. A value of 0.0.0.0 specifies that UDP 
broadcast packets are not forwarded to any host.

•

udp-port-list—Specifies the destination UDP port number to which to 
forward broadcast packets. (Range: 1–65535)

Default Configuration

Forwarding of User Datagram Protocol (UDP) broadcast packets received on an 
interface to a specific (helper) address is disabled.

If udp-port-list is not specified, packets for the default services are forwarded to 
the helper address.

Command Mode

Global Configuration mode

User Guidelines

To use this command, you must put the switch into routing mode using the set
