Usage guidelines
LMI protocol maintains frame relay protocol PVC table, including notifying PVC increasing, detecting
PVC deleting, monitoring PVC status changing and authenticating link integrity. The system usually
supports three standard LMI protocols ITU-T Q.933 Appendix A, ANSI T1.617 Appendix D, and
nonstandard-compatible LMI protocol.
The bi-direction keyword specifies the interface to respond to Status-Enquiry messages form network side
when operating in frame relay DTE mode. It does not enable frame relay network specifications of the
network side and has no effect on frame relay DCE interfaces. This keyword is needed only when the
current device is to communicate with routers that require bi-directional LMI, such as Motorola Vanguard
5.3 or previous versions.
