Data bits described in the following table are set in the Service > Service Parameters area in

Cisco CallManager Administration. Following are two examples of desired values based on the

particular problem.

• The recommended value for normal system debugging is SdlTraceDataFlags=0x110

• The recommended value when tracking problems with SDL links is 0x13D (non-

compacted trace; if a compact trace is desired, bit 0x200 must be set. It can be set in

combination with any other bits)

SDLTraceDataFlags Definitions

SDLTraceDataFlag Value Definition

TraceSdlLinkState = 0x001 Enable trace of SDL Link Initialization

TraceSdlLowLevel = 0x002 Enable tracing of low-level SDL events, for example, fileOpen,

socket events, and so on

TraceSdlLinkPoll = 0x004 Enable tracing of SDL Link Poll message

TraceSdlLinkMsg = 0x008 Enable tracing of SDL Link Message

traceRawData = 0x010 Enable raw signal data trace on all signals

TraceSdlTagMap = 0x020 Enable tag mapping

traceCreate = 0x100 Enable process create and stop traces

TraceNoPrettyPrint = 0x200 Disable pretty printing of trace files

Disk Space Warning

IMPORTANT: Be advised that information obtained from this interface could be very detailed,

and therefore consume a large amount of disk space. For this reason, we advise you to turn on

the trace file for a specific amount of time, then review the information and turn off the trace.
