Description
Specify one or more interfaces, or a range of interfaces,
that are within a specified group on which the DHCP local server is
enabled. You can repeat the interface 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 relay
agent.interface-name
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 supports only 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.
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.
Required Privilege Level
system—To view this statement in the configuration.
system-control—To add this statement to the configuration.
