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 and 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

A packet capture utility has been provided to aid with problem isolation when LMI errors are detected. Using this utility, any enabled frame relay link on the user data port or network interface 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.

The LMI Trace Log also provides access to captured packet information. See Viewing Captured Packets from the Menu-Driven User Interface for 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.Select an enabled frame relay link, or Capture Interface, either Net1-FR1 or 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, FTP Operation, for additional information about this feature.
