interface (LLDP)

Syntax

Hierarchy Level

Description

Configure Link Layer Discovery Protocol (LLDP) on all interfaces or on a particular interface.

Note:

On MX Series and T Series routers, you run LLDP on a physical interface, such as ge-1/0/0, and not at the logical interface (unit) level.

Starting with Junos OS Release 14.2, on MX Series devices, you can also configure LLDP on management interfaces, such as fxp or me.

LLDP is not supported on vme interfaces.

For information about interface names, see Interface Naming Overview. For information about interface names for TX Matrix routers, see TX Matrix Router Chassis and Interface Names. For information about FPC numbering on TX Matrix routers, see Routing Matrix with a TX Matrix Router FPC Numbering.

For information about extended port names in the Junos Fusion technology, see Understanding Junos Fusion Ports.
