Local management interface

 

The System i™ platform uses the local management interface (LMI) to exchange status information between the frame-relay network (or the frame handler system) and systems attached to the network (terminal equipment).

The LMI uses data link connection identifier 0 (DLCI 0) to provide verification of the physical connection and status for logical connections.

LMIMODE parameter

Use the LMIMODE parameter on the network interface description to specify the type of LMI exchange done by the System i platform. You can configure the system as terminal equipment (*TE), or you can configure the System i platform as terminal equipment (*ANNEXA). When you specify *TE, you use ANNEX D, and when you specify *ANNEXA, you use ANNEX A.

You can also configure the system to exchange no LMI information (*NONE).

Your LMI type must match the values of the network provider. If ANNEX D or ANNEX A are unavailable, ask the network provider to turn LMI off and set the System i platform to *NONE.

When you make a connection without a network (using a modem eliminator or nonswitched line), you can configure the System i platform as a frame handler (LMIMODE(*FH)). In this configuration, the system responds to LMI messages as an FH.

• Parameters that control exchanges of information over local management interface
  The polling interval (POLLITV) and full inquiry interval (FULLINQITV) parameters are used to control the exchange of information over the local management interface (LMI).

• Local management interface exchanges
  To maintain the exchanged status information between the frame-relay network and the systems attached to it, use the keep-alive exchange and permanent virtual circuit (PVC) status change.
