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 8-6 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. 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.
