Juniper EX3400 Features Guide

7. (Optional) Configure settings for a DHCP relay group interface that override the
settings at the global and group levels, using these statements:
[edit forwarding-options dhcp-relay group group-name interface interface-name]
user@switch# exclude
user@switch# set overrides
user@switch# set trace
user@switch# set upto upto-interface-name

Configuring a DHCP Server on Switches (CLI Procedure)•
• Configuring a DHCP Client (CLI Procedure) on page 17
• Understanding the Extended DHCP Relay Agent for EX Series Switches
Example: Minimum DHCP Relay Agent Configuration
This example shows the minimum configuration you need to use the extended DHCP
relay agent on the router or switch:
[edit forwarding-options]
dhcp-relay {
server-group {
test 203.0.113.21;
}
active-server-group test;
group all {
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 a server group and an active server group named test with IP address
203.0.113.21. The DHCP relay agent configuration is applied to a group named all. Within
this group, the DHCP relay agent is enabled on interface fe-0/0/2.0.
