Local Management Interface


Local Management Interface is a term for some signaling standards used in networks, namely frame relay and Carrier Ethernet.

Frame relay

LMI is a set of signalling standards between routers and frame relay switches. Communication takes place between a router and the first frame relay switch to which it is connected. Information about keepalives, global addressing, IP Multicast and the status of virtual circuits is commonly exchanged using LMI.
There are three standards for LMI:
Ethernet Local Management Interface is an Ethernet layer operation, administration, and management protocol defined by the Metro Ethernet Forum for Carrier Ethernet networks. It provides information that enables auto configuration of customer edge devices.
