IUA Traces
IUA Traces
The existing Cisco BTS 10200 Softswitch trace capability is used to troubleshoot IUA and SCTP. Use
the get-trace and set-trace CLI commands to enable and disable various trace details of the IUA/SCTP
protocol at run time. Set the IUM process trace levels to INFO5 to enable IUA/SCTP traces.
The Call Agent table has an additional field, IUA-DEBUG-LEVEL, to enable and disable various trace
details of the IUA stack using the get-trace and set-trace commands. The IUA-DEBUG-LEVEL can be
set to any of the following:
•
ERROR (Default)— Only error traces
•
STATE— State transitions and errors.
•
PACKET— IUA packets sent or received and errors
•
ALL— SCTP signals received from SCTP stack, state transitions, IUA packets sent or received and
errors.
The following example CLI command enables specific trace details:
set-trace call-agent id=CA146; trace-sctp-api=y; trace-sctp-txrxchunks=y;
trace-sctp-state=y; trace-sctp-signal=y; trace-sctp-multihome=y; trace-sctp-congestion=y;
trace-sctp-init=y
;
The following example displays the output from the get-trace command:
get-trace call-agent id=CA146
CA ID -> CA146
RESULT -> ADM configure result in success
REASON -> ADM executed successfully
TRACE SCTP API -> Y
TRACE SCTP TXRXCHUNKS -> Y
TRACE SCTP STATE -> Y
TRACE SCTP SIGNAL -> Y
TRACE SCTP MULTIHOME -> Y
TRACE SCTP CONGESTION -> Y
TRACE SCTP INIT -> Y
IUA DEBUG LEVEL -> ERROR
