Use the Learned DLCI Display as a Troubleshooting Aid

Article Number: T010
Article Type: Tip
Modified: October 28, 1999

SUMMARY

The Orbitor's Frame Relay Auto-Learning is not only a wonderful ease-of-configuration feature, but it can be a powerful troubleshooting tool too. It can serve as a validation of the information supplied to you by your Frame Relay service provider. You may display the PVCs/DLCIs that have been learned by the Orbitor by using the Learned Summary Display.

MORE INFORMATION

Available on the "Remote Site Setup" menu, the Display Learned Summary option displays the current results of the latest Frame Relay LMI Full Status (FSR) update received by the Orbitor. This display will show the DLCI's reported from the frame relay service and their corresponding state. This status display will be updated after each enquiry interval.

       Link 1 LMI State: Up   Link 2 LMI State: Up
            * - Up E - Enabled D - Disabled

• Link: The link interface used for this PVC in this remote site profile.
• DLCI: The Data Link Connection Identifier (DLCI) value used for this PVC in this remote site profile.
• State: The state of the PVC in this remote site profile. An asterisk (*) beside the state indicates that the PVC is currently up.

The display above shows that Link 1 has seven active DLCIs, and Link 2 has three active DLCIs. Across both links, only five DLCIs are presently considered up and operational, communicating with a partner in their respective remote location.

Since this information is derived from the LMI Full Status Report, this display can be used as a validation of the information the Frame Relay service provider has given you. By relating this display to what should be present and active, a quick determination of what is valid and what isn't can be made.
