MultiFRAD 100-Series User Guide

FR111A

The DLCI Statistics dialog box shows the individual DLCI status and statistics. This information can

be helpful in determining if the DLCI is active, if it is going up and down, and if the MultiFRAD is

experiencing frame relay network congestion (FECN/BECN). It also gives an indication of the

momentary throughput on the DLCI.

When trying to troubleshoot a frame relay circuit, once it has been established that management

frames are being sent and received, the next step is to determine whether the DLCI has become

active. This dialog box will give that information. A FRAD needs to be present at both ends for the

DLCI to be active. Keep in mind that the frame relay network tells the FRAD the status of the PVC

with one of its status responses. But the network will not say the PVC is active until it has

established management communication at both ends of the PVC. If the FRADs at both ends of the

PVC show that they are communicating with the frame relay network and the DLCI at both ends

shows active, but there is still a communication problem over that PVC, then there may be a problem

with your service provider.
