Parameter

ansi: Standard LMI protocol type of ANSI T1.617 Appendix D.

 

nonstandard: Nonstandard compatible LMI protocol type.

 

q933a: Standard LMI protocol type of Q.933 Appendix A.

 

bi-direction: Specifies to respond to status-enquiry messages from network side

 

in frame relay DTE mode. The support of this keyword varies with device models.

Description

Use the fr lmi type command to configure the frame relay LMI protocol type.

 

Use the undo fr lmi type command to restore the default.

 

By default, the LMI protocol type is q933a.

 

LMI protocol is used to maintain 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-directionkeyword 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. Normally, this keyword is only needed when the

 

current device is to communicate with routers that require bi-directional LMI, such

 

as Motorola Vanguard 5.3 (or former versions).

Example

# Set the frame relay LIMI type of Serial 2/0 to nonstandard compatible protocol.
