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.
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.
Required Privilege Level
system—To view this statement in the configuration.
