•
ip_evt_mask
The input 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 received by Q.SAAL. Care should be taken when
tracing messages, as system throughput may be reduced. The fields in the trace mask cause the events
indicated in the table below to be traced.
•
mgmt_evt_mask
The management event trace mask. This is a 16-bit value with bits set to 1 to cause an event indication
message to be sent to the management module for the events shown. The fields in the trace mask cause
the events indicated in Figure 4 to be traced. By default, the SL_FAIL, SL_CONG, ERROR and STATE bits
are set.Note: Take care when sending trace mask set requests. Failure to set bits 0, 1 2 and 3 prevents
the generation of MGT_MSG_SS7_STATE state change indications and MGT_MSG_SS7_EVENT Q.791
event indications.
