Release Information Statement introduced in Junos OS Release 9.2.

Statement introduced in Junos OS Release 12.1 for EX Series switches.

Support for the allow-no-end option introduced in Junos OS Release 14.1X53-D15 for EX

Series switches.

Statement introduced in Junos OS Release 12.3X48-D10 for SRX Series devices.

Description Override the default configuration settings for the extended DHCP local server. Specifying

the overrides statement with no subordinate statements removes all DHCP local server

overrides at that hierarchy level.

• To override global DHCP local server configuration options, include the overrides

statement and its subordinate statements at the [edit system servicesdhcp-local-server]

hierarchy level.

• To override configuration options for a named group of interfaces, include the

statements at the [edit system services dhcp-local-server group group-name] hierarchy

level.
