DSI SS7MD Programmer’s Manual Issue 3
6.6.5 SS7_MSG_TRACE_MASK – Set Trace Mask Request
Synopsis
Message issued to Q.SAAL module to set the mask of which messages should be traced
Message Format
Description
The Q.SAAL module supports comprehensive tracing options on a per-link and per-primitive basis. The
module can be configured to trace any message received or transmitted and a number of management
events. This message is used to selectively enable tracing of events. It can be used at any time during
operation and continues to be effective until the next Trace Mask Set Request is received for the same link.
Traced events are indicated to the management module using the MGT_MSG_TRACE_EV Event Indication.
Parameters
The SS7_MSG_TRACE_MASK message includes the following parameters:
• op_evt_mask
The output event trace mask. This is a 16-bit value with bits set to 1 to cause a trace message to be sent
to the management module whenever a message is issued by Q.SAAL. Care should be taken when
tracing messages because the system throughput may be reduced. The fields in the trace mask cause
the events indicated in the table below to be traced..
