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
, 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
on page 6-6 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. 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.
