Local Management Interface

LMI. A protocol used to communicate link status and permanent virtual circuit (PVC) status in Frame Relay. Two types of LMI are available on Frame Relay: the original proprietary Cisco/Stratacom LMI, and the ANSI T1.617 Annex-D LMI. Although the PortMaster supports both, LMI on the PortMaster refers to the Cisco/Stratacom implementation. See also Annex-D.
