IP Helper Commands
This section describes the commands to configure a DHCP relay agent with multiple DHCP 
server addresses per routing interface, and to use different server addresses for client 
packets arriving on different interfaces on the relay agent.

show ip helper statistics 
command to zero. 
Format
clear ip helper statistics
Mode
ip helper-address (Global Config)
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. 
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.
