8. Troubleshooting

Troubleshooting Management Link Feature

A dedicated troubleshooting management link is available to help service providers isolate device problems within their networks. This feature allows Telnet or FTP access to the unit on this link. Troubleshooting over this link is essentially transparent to customer operations. No alarms or SNMP traps are generated to create nuisance alarms for the customer.

See Configuring Node IP Information in Chapter 4, Configuration Options, for additional information about this feature.

LMI Packet Capture Utility Feature

The FrameSaver DSL CSU/DSU provides a packet capture utility to aid with problem isolation when LMI errors are detected. Using this utility, any enabled frame relay link on the user data port can be selected. The utility captures any LMI packets sent or received, and writes them to a data file called lmitrace.syc in the system’s data directory so the data can be uploaded and transferred to a Network Associates Sniffer for analysis. This feature does not apply to the router.

The LMI Trace Log also provides access to captured packet information. See Viewing LMI Captured Packets from the User Interface on page 8-6for additional information on this feature.

Procedure

To use this utility:

1. Select the LMI Packet Capture Utility.

Main Menu Control LMI Packet Capture Utility

2.In the first field,→Capture Interface,→select the enabled frame relay link, Port-1.

3.Start packet capture.

While capturing data, the status is Active. Packets in Buffer indicates the number of packets that have been captured. Up to 8000 packets can be held. When the buffer is full, the oldest packets will be overwritten.

4.To stop the utility, press Enter. The field toggles back to Start.

5.Upload the data file holding the collected packets to a diskette so the information can be transferred to a Network Associates Sniffer for debugging/decoding.

See Transferring Collected Data in Chapter 7, Operation and Maintenance, for additional information about this feature.
