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

deviceUse the device interface description. Only available for MX Series platform configuration.
logicalUse the logical interface description. Only available for MX Series platform configuration.
