Cisco IOS XE Integrated Session Border Controller Configuration Guide for the Cisco ASR 1000 Series Aggregation Services Routers

Chapter 2 Configuring Integrated Session Border Controller
Configuration Examples
Note that some messages may be displayed on the standby Route Processor (RP) because some of the
components remain in the active stage on the standby RP and may produce those messages.
The lower the log level, the more syslog bandwidth is taken up.
Integrated Session Border Controller (SBC) debug commands that set the logging level and the H.248
protocol message filter, such as debug sbc log-level and debug sbc filter, can be enabled at the same
time.
The logging level command works with Integrated SBC and Cisco IOS debug commands as follows:
• If logging and logging level are enabled by the logging level command, logging can only be disabled
by the logging level command. The undebug all and no debug sbc log-level commands have no
effect.
• If logging and logging level are enabled by a debug command, logging can be disabled by the
undebug all and no debug sbc log-level commands.
• If two different logging levels are set by both a debug command and the logging level command,
the lower logging level is applied.
• If the same level is set using both the logging level command and a debug command—to turn off
logging for that level, you must disable logging using both the logging level command and the
debug command.
Example H.248 Log Output
The following shows sample log output produced on an H.248 ADD request with logging level set to 30:
*Sep 10 06:38:39.039: %SBC-7-MSG-2E01-0092: SBC/MG-CTRL: (gctarecv.c
1397) Application has completed processing a transaction asynchronously
Transaction ID = 3
Transaction type = 0X01
*Sep 10 06:38:49.539: %SBC-7-MSG-2E01-0050: SBC/MG-CTRL: (gctphash.c
701) A hash table has been resized.
The previous size of the hash table was 1024 entries.
The new size of the hash table is 512 entries.
