Juniper EX3400 Features Guide

NOTE: The extended DHCP local server and the address-assignment pools
used by the server must be configured in the same logical system and routing
instance.

Example: Minimum Extended DHCP Local Server Configuration
This example shows the minimum configuration you need to use for the extended DHCP
local server on the router or switch:
[edit system services]
dhcp-local-server {
group group_one {
interface fe-0/0/2.0;
}
}
NOTE: The interface type in this topic is just an example. The fe- interface
type is not supported by EX Series switches.
This example creates the server group named group_one, and specifies that the DHCP
local server is enabled on interface fe-0/0/2.0 within the group. The DHCP local server
uses the default pool match configuration of ip-address-first.
