'''Local Management Interface (LMI)''' is a term for some signaling standards used in networks, namely [[Frame Relay]] and [[Carrier Ethernet]].

*[[== Frame Relay]] ==

LMI is a signalingset standardof usedsignalling bybetweenstandards routersbetween [[Router (computing)|router]]s and frameFrame relayRelay switches. Communication takes place between a router and the first frameFrame relayRelay switch to which it's connectedis toconnected. Information about keepalives[[keepalive]]s, global addressing, multicasting[[IP multicast]] and the status of [[virtual circuits]] is commonly exchanged using LMI.

There are three standards for LMI:

Ethernet Local Management Interface (E-LMI) is an Ethernet layer operation, administration, and management (OAM) protocol defined by the [[Metro Ethernet Forum]] (MEF) for Carrier Ethernet networks. It provides information that enables auto configuration of customer edge (CE) devices.
