This section describes software tools that can help you in troubleshooting.

• Alarms and error messages

• Call traces

• System logs

• CLI queries

Alarms and Error Messages

The Cisco BTS 10200 Softswitch software generates alarms and error messages to indicate problems

with processes, routes, linksets, signaling links, and bearer channels. Refer to the Cisco BTS 10200

Softswitch Software Release 4.1 Operations Guide for detailed information on system alarms and error

messages.

The Error Message Message Decoder Tool is available to registered Cisco.com users at

http://www.cisco.com/cgi-bin/Support/Errordecoder/home.pl

There is also a Messages and Recovery Procedures Guide for every set of CatOS or Cisco IOS LAN

Documentation. For example, for CatOS 8.1 use the URL

:http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sw_8_1/msg_gd/emsg.htm

The Output Interpreter also now incorporates the functionality of the Error Message Decoder tool

https://www.cisco.com/cgi-bin/Support/OutputInterpreter/home.pl. Also, you may be interested in the

TAC Advanced Search's error message data collection at

http://www.cisco.com/kobayashi/support/tac/s_tac.shtml

(when logged in with your registered Cisco.com user ID and password).

To decode error messages, you paste your one- or two-line console error message into the Output

Interpreter. Your analysis will include an explanation of the message, any recommended actions to take,

and a list of related support resources. The Output Interpreter can decode error messages from devices

running Cisco IOS and Catalyst OS.

Call Traces

The Cisco BTS 10200 Softswitch can generate call traces that capture call-processing activity by

following the call from a specified destination through the Cisco BTS 10200 Softswitch to see where it

fails. Call failure location is determined using the following information provided in the call trace:

• The protocol data units (PDUs) that the Cisco BTS 10200 Softswitch receives

• How the Cisco BTS 10200 Softswitch decodes the PDU

• The PDUs that the Cisco BTS 10200 Softswitch sends out
