Juniper EX3400 Features Guide

NOTE: If you delete the DHCP server configuration, DHCP server bindings
might still remain. To ensure that DHCP bindings are removed, issue the clear
dhcp server binding command before you delete the DHCP server configuration.

Overriding Default DHCP Local Server Configuration Settings
Subscriber management enables you to override certain default DHCP local server
configuration settings. You can override the configuration settings at the global level, for
a named group of interfaces, or for a specific interface within a named group.
•
To override global default DHCP local server configuration options, include the overrides
statement and its subordinate statements at the [edit system servicesdhcp-local-server]
hierarchy level.
•
To override DHCP local server configuration options for a named group of interfaces,
include the statements at the [edit system services dhcp-local-server group group-name]
hierarchy level.
•
To override DHCP local server configuration options for a specific interface within a
named group of interfaces, include the statements at the [edit system services
dhcp-local-server group group-name interface interface-name] hierarchy level.
•
To configure overrides for DHCPv6 local server at the global level, group level, or
per-interface, use the corresponding statements at the [edit system services
dhcp-local-server dhcpv6] hierarchy level.
