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

LMI is a set of signalling standards between [[Router (computing)|router]]s and frameFrame relayRelay switches. Communication takes place between a router and the first frameFrame relayRelay switch to which it is connected. Information about [[keepalive]]s, global addressing, [[IP Multicastmulticast]] and the status of [[virtual circuits]] is commonly exchanged using LMI.

There are three standards for LMI:
