interface (DHCP Relay Agent)

 

Syntax

Hierarchy Level

Release Information

Statement introduced in Junos OS Release 8.3.

Options upto and exclude introduced in Junos OS Release 9.1.

Support at the [edit ... dhcpv6] hierarchy levels introduced in Junos OS Release 11.4.

Description

Specify one or more interfaces, or a range of interfaces, that are within a specified group on which the DHCP or DHCPv6 relay agent is enabled. You can repeat the interface interface-name statement to specify multiple interfaces within a group, but you cannot specify the same interface in more than one group. Also, you cannot use an interface that is being used by the DHCP local server. Use the statement at the [edit ... dhcpv6] hierarchy levels to configure DHCPv6 support.

EX Series switches do not support DHCPv6.

Note

DHCP values are supported in integrated routing and bridging (IRB) configurations. When you configure an IRB interface in a network that is using DHCP, the DHCP information (for example, authentication, address assignment, and so on) is propagated in the associated bridge domain. This enables the DHCP server to configure client IP addresses residing within the bridge domain. IRB currently only supports static DHCP configurations. .

Options

exclude—Exclude an interface or a range of interfaces from the group. This option and the overrides option are mutually exclusive.

interface-name—Name of the interface. You can repeat this option multiple times.

overrides—Override the specified default configuration settings for the interface. The overrides statement is described separately.

upto-interface-name—Upper end of the range of interfaces; the lower end of the range is the interface-name entry. The interface device name of the upto-interface-name must be the same as the device name of the interface-name.

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