Configuration Guide, Release 12.4 for these procedures:

Checking (validating) the relay agent information
•
Configuring the relay agent forwarding policy
Specifying the Packet Forwarding Address
If the DHCP server and the DHCP clients are on different networks or subnets, you must configure the switch
with the ip helper-address address interface configuration command. The general rule is to configure the
command on the Layer 3 interface closest to the client. The address used in the ip helper-address command
can be a specific DHCP server IP address, or it can be the network address if other DHCP servers are on the
destination network segment. Using the network address enables any DHCP server to respond to requests.
Beginning in privileged EXEC mode, follow these steps to specify the packet forwarding address:
