For MX Series Platforms

Description

Use the interface description rather than the interface name (which is the default value) in the circuit ID or remote ID value in the DHCP option 82 information.

The textual description is configured using the description statement at the [edit interfaces interface-name] hierarchy level. If you specify that the textual description be used and no description is configured for the interface, DHCP relay defaults to using the Layer 2 interface name. When you use the interface description rather than the interface name, the interface description has to be specified under interface unit ("set interfaces ge-0/0/0 unit 0 description "client"). If you do not do this, then the interface name is used.

Options

device

Use the device interface description. Only available for MX Series platform configuration.

logical

Use the logical interface description. Only available for MX Series platform configuration.

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 9.3.

Hierarchy level [edit vlans vlan-name forwarding-options dhcp-security] introduced in Junos OS Release 13.2X50-D10. (See Using the Enhanced Layer 2 Software CLI for information about ELS.)

Hierarchy level [edit bridge-domains bridge domain name forwarding-options dhcp-security] introduced in Junos OS Release 14.1 for the MX Series.
