Dhcp Relay Agent Configuration - HP 445946-001 Application Manual

DHCP relay agent configuration

To enable the switch to be the BOOTP forwarder, you need to configure the DHCP/BOOTP server IP
addresses on the switch. Generally, you should configure the command on the switch IP interface closest
to the client so that 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 HP 10GbE switch 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 provides 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
>> Bootstrap Protocol Relay# addr2
>> Bootstrap Protocol Relay# on
>> Bootstrap Protocol Relay# off
>> Bootstrap Protocol Relay# cur
Additionally, DHCP Relay functionality can be assigned on a per interface basis. Use the following
command to enable the Relay functionality:
>> # /cfg/l3/if <1-249>/relay ena
(Set IP address of BOOTP server)
(Set IP address of 2nd BOOTP server)
(Globally turn BOOTP relay on)
(Globally turn BOOTP relay off)
