Mediant 8000
Board Logging (syslog) configuration may also be configured for a specific Media
Gateway board (e.g., it is possible to send Syslog messages from different Media
Gateway boards to different Syslog servers). To do this, at the Board level, set the
UseBoardLoggingGWLevelConfiguration parameter to no and provision the
following parameters at the Board level (similar to those at the Media Gateway level):

'EnableBoardLoggingOnSC'

'EnableBoardLoggingOnExternalServer'

'BoardLoggingExternalIP'
49.1.1.1 Displaying VoIP Board Log Files
In the default configuration, the Active SC board acts as a Syslog server. It intercepts
all syslog messages generated by the Media Gateway boards and stores them in the
log files.
The log files may be viewed via the following CLI command (available to all CLI
users):
log [<options>] board# <slot number>
Without any options, the log command displays the new logs as they are generated
by the Media Gateway boards. For example, to display the logs of Media Gateway
board in slot 8, use the log board#8 command.
With option -<number>, the log command displays the last <number> of log
messages. For example to see the last 100 log messages from Media Gateway board
in slot 6, use the log -100 board#6 command.
With option -f, the log command displays the complete log file. For example, log –f
board#10 command displays the full log of Media Gateway board in slot 10.
Option -h allows viewing the history of the log files (10 last log files are stored in the
history).
49.1.2 SIP Board Syslog Level
Media Gateway boards use the Syslog protocol to generate log and error messages.
The Syslog protocol is an event notification protocol which allows a device to send
event notification messages across IP networks to event message collectors, also
known as Syslog servers. Since each process, application and operating system is
unique, there is minimal uniformity for Syslog messages. For this reason, no
assumption is made regarding the contents of the messages other than the minimum
requirements of its priority.
Media Gateway SIP boards act as a Syslog client and are capable of generating the
following message levels:

Only Emergency level Errors and Warning messages are enabled (debug
disable).

Warning level-Flow debugging is enabled (debug level 1).

Debug level-Flow, device interface, stack interface, session manager, and device
interface expanded debugging are enabled (debug level 5).
