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 |
