Outputting system information by source module
The system is composed of a variety of protocol modules, board drivers, and configuration modules. The
system information is classified, filtered, and output according to source modules. You can use the
info-center source ?
command to view the supported information source modules.
Default output rules of system information
The default output rules define the source modules allowed to output information on each output
destination, the output information type, and the output information level as shown in
. The
following applies to all modules by default:
•
All log information is allowed to be output to the web interface and log file. Log information with
severity level equal to or higher than informational is allowed to be output to the log host. Log
information with severity level equal to or higher than informational is allowed to be output to the
console, monitor terminal, and log buffer. Log information is not allowed to be output to the trap
buffer or the SNMP module.
•
All trap information is allowed to be output to the console, monitor terminal, log host, web interface,
and log file. Trap information with severity level equal to or higher than informational is allowed to
