Overriding Default DHCP Local Server Configuration Settings

Subscriber management enables you to override certain default DHCP and DHCPv6 local server configuration settings. You can override 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 services dhcp-local-server] or [edit system services dhcp-local-server dhcpv6] 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] or [edit system services dhcp-local-server dhcpv6 group] 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] or [edit system services dhcp-local-server dhcpv6 group group-name interface] hierarchy level.

To override default DHCP local server configuration settings:

1. Specify that you want to configure override options.

   Global override:

   [edit system services dhcp-local-server]user@host# edit overrides

   Group level override:

   [edit system services dhcp-local-server]user@host# edit group boston overrides

   Per-interface override:

   [edit system services dhcp-local-server]user@host# edit group boston overrides interface fe-1/0/1.1
2. (Optional) Override the maximum number of DHCP clients allowed per interface.
