Hierarchy Level

[edit system services dhcp-local-server dhcpv6]
[edit system services dhcp-local-server dhcpv6 group group-name]
[edit system services dhcp-local-server dhcpv6 group group-name interface interface-name]

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 dhcpv6 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 dhcpv6 group group-name interface interface-name] hierarchy level.

  • Use the DHCPv6 hierarchy levels to override DHCPv6 configuration options.

Options

interface-client-limit number—Sets the maximum number of DHCP clients per interface allowed for a specific group or for all groups. A group specification takes precedence over a global specification for the members of that group.

  • Range: 1 through 500,000

  • Default: No limit

Required Privilege Level

system—To view this statement in the configuration.

system-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 10.4.
