DHCP Relay Implementation

The OmniSwitch allows you to configure the DHCP Relay feature in one of two ways. You can set up a
global DHCP request or you can set up the DHCP Relay based on the VLAN of the DHCP request. Both
of these choices provide the same configuration options and capabilities. However, they are mutually
exclusive. The following matrix summarizes the options.

Global DHCP

For the global DHCP service, you must identify an IP address for the DHCP server.

Setting the IP Address

The DHCP Relay is automatically enabled on a switch whenever a DHCP server IP address is defined by
using the

ip helper address

command. There is no separate command for enabling or disabling the relay

service. You should configure DHCP Relay on switches where packets are routed between IP networks.
The following command defines a DHCP server address:

-> ip helper address 125.255.17.11

The DHCP Relay forwards BOOTP/DHCP broadcasts to and from the specified address. If multiple
DHCP servers are used, one IP address must be configured for each server. You can configure up to 256
addresses for each relay service.

To delete an IP address, use the

no

form of the

ip helper address

command. The IP address specified with

this syntax will be deleted. If an IP address is not specified with this syntax, then

all

IP helper addresses

are deleted. The following command deletes an IP helper address:

-> ip helper no address 125.255.17.11
