LMI Management (Frame Relay links)
LMI Configuration
Frame Relay Local Management Interface. The Frame Relay Local Management Interface (LMI) is a mech-
anism that two separate frame relay systems can use to communicate the status of the interface. The LMI inter-
face allows dynamic updates on the status of the DLCI connections and the congestion state of the network.
The IPLink implements all three versions of LMI available within the frame relay network. These are defined
in table 3:
Note LMI uses DLCI 0, but ANSI/CCITT has also reserved 1–15. Best practice
(per the recommendation) is to use only DLCIs 16–991 for FR data PVCs,
and DLCIs 0–15 for LMI PVCs.
