Syntax

Hierarchy Level

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 services dhcp-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.

  • To override 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.

  • Use the [edit system services dhcp-local-server dhcpv6] hierarchy level to override DHCPv6 configuration options.

Note

By default, jdhcp does not process DHCPINFORM message. Only after you enable the overrides command using the set system services dhcp-local-server overrides process-inform statement, jdhcp starts processing the DHCPINFORM message.

The remaining statements are explained separately. Search for a statement in CLI Explorer or click a linked statement in the Syntax section for details.

The interface-client-limit statement is not supported in the [edit system services dhcp-local-server dhcpv6] hierarchy level.

The asymmetric-prefix-lease-time, delegated-pool, multi-address-embedded-option-response, and rapid-commit statements are supported in the [edit system services dhcp-local-server dhcpv6 ...] hierarchy level only.
