# syslogd -r &
Ensure that the syslogd process is started with the -r option on a Linux log host.
After the above configurations, the system will be able to record log information into the log file.
Outputting Log Information to the Console
Log information with a severity higher than informational will be output to the console;
The source modules are ARP and IP.
Figure 1-3 Network diagram for sending log information to the console
# Enable information center.
[Sysname] info-center enable
# Use channel console to output log information to the console (optional, console by default).
[Sysname] info-center console channel console
# Disable the output of log, trap, and debugging information of all modules on channel console.
[Sysname] info-center source default channel console debug state off log state off trap state
As the default system configurations for different channels are different, you need to disable the output
of log, trap, and debugging information of all modules on the specified channel (console in this example)
first and then configure the output rule as needed so that unnecessary information will not be output.
# Configure the information output rule: allow log information of ARP and IP modules with severity equal
to or higher than informational to be output to the console. (Note that the source modules allowed to
output information depend on the device model.)
