The following information is provided for the LMI Trace Log:

The internal LMI record number assigned to the packet (1–8000) and the

￿amount of time the utility was running when the packet was captured.

The maximum amount of time displayed is 4,294,967 s (seconds). The display is reset to 1 second when this amount of time is exceeded.

The captured packet message, either Status Message or Status Enquiry Message and the number of packet bytes.

The LMI Type identified in the Protocol Discriminator portion of the captured packet and the DLCI number for the packet.

The type of information contained in the captured packet, either Sequence Number Exchange or Full Status Report.

The Send and Receive (Rcv) sequence numbers from the captured packet

￿(0–255).

On the Packets Received side of the screen, PVC status for up to ten DLCIs can be shown; including the DLCI number, the active bit status, and if Standard LMI is running, the DLCI’s CIR value.
