CHAPTER 62 Syslog and Debug Recording
# configure voip
(config-voip)# interface e1-t1 1/1
(e1-t1 1/1)# trace-level full-isdn
■ To start a PSTN trace:
● Per trunk: Debugging per trunk is configured in the Logging Filters where there is an option
to start and stop the trace:
(config-troubleshoot)# logging logging-filters <Table Row Index>
For more information on the Logging Filters table, see
page 1096.
Note: The trace level is configured using the interface command described in the beginning
of this section.
● All trunks: You can perform PSTN traces for all trunks for which you have configured trace
levels (using the interface command described in the beginning of this section). To start
the trace for all these trunks, use the following command:
# debug debug-recording <IP Address of Debug Recording Server> pstn-trace
■ To enable sending traces to Syslog: To send the PSTN traces to a Syslog server, use the
following command:
(config-troubleshoot)# pstn-debug on
Note:
● If you send traces to a Syslog server, you must configure the trace level to q931-raw-data.
● Changing the command to on or off requires a device reset.
PSTN traces may affect performance.

Configuring Syslog

This section describes how to configure Syslog. To filter Syslog messages, see
Filter Rules.

Syslog Message Format

The Syslog message is sent from the device to a Syslog server as an ASCII (American Standard
Code for Information Interchange) message. Syslog uses UDP as its underlying transport layer
mechanism. By default, UDP port 514 is assigned to Syslog, but this can be changed (see
Enabling Syslog).
Syslog includes two types of log messages:
■ SIP call session logs: Logs relating to call sessions (e.g., call established). These logs are
identified by a session ID ("SID"), described in detail in the table below. The following is an
example of a SIP-session related Syslog message:
13:10:57.811 : 10.13.4.12 : NOTICE : [S=235][SID:2ed1c8:96:5] (lgr_flow)(63)
UdpTransportObject#0- Adding socket event for address 10.33.2.42:5060 [Time: 04-19-
2012@18:29:39]
