Dhcp Relay Agent Configuration

Alteon OS Application Guide

To enable the GbE Switch Module to be the BOOTP forwarder, you need to configure the DHCP/BOOTP server IP addresses on the switch. You generally configure the IP interface on the client side to match the client’s subnet, and configure VLANs to separate client and server subnets. The DHCP server knows from which IP subnet the newly allocated IP address should come.

The following figure shows a basic DHCP network example:

In GbE Switch Module implementation, there is no need for primary or secondary servers. The client request is forwarded to the BOOTP servers configured on the switch. The use of two servers provide failover redundancy. However, no health checking is supported.

Use the following commands to configure the switch as a DHCP relay agent:

>> # /cfg/l3/bootp
>> Bootstrap Protocol Relay# addr	(Set IP address of BOOTP server)
>> Bootstrap Protocol Relay# addr2	(Set IP address of 2nd BOOTP server)
>> Bootstrap Protocol Relay# on	(Globally turn BOOTP relay on)
>> Bootstrap Protocol Relay# off	(Globally turn BOOTP relay off)
>> Bootstrap Protocol Relay# cur	(Display current configuration)

Additionally, DHCP Relay functionality can be assigned on a per interface basis. Use the fol- lowing command to enable the Relay functionality:

>> # /cfg/l3/if <interface number>/relay ena
