messages.
The following information is provided:
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 seconds (s), which is
reset to 1 second when this amount of time is exceeded.
The type of message, either Status or Status Enquiry, from the captured
packet, and the number of bytes in the packet.
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

The send and receive (rcv) sequence numbers from the captured packet
(0–255).

can be shown. It shows the DLCI number, its active bit status, and if Standard
LMI is running, the DLCI’s CIR value.
