Outputting log information to a Linux log host
Send log information to a Linux log host with an IP address of 188.8.131.52/16;
Log information with severity equal to or higher than informational will be output to the log host;
All modules can output log information.

Before the configuration, make sure that Device and PC are reachable.
Configure the device
# Enable information center.
[Sysname] info-center enable
# Specify the host with IP address 184.108.40.206/16 as the log host. Use channel loghost to output log
information (optional, loghost by default), and use local5 as the logging facility.
[Sysname] info-center loghost 220.127.116.11 channel loghost facility local5
# Disable the output of log, trap, and debugging information of all modules on channel loghost.
[Sysname] info-center source default channel loghost debug state off log state off trap
Because the default system configurations for different channels are different, you need to first disable the
output of log, trap, and debugging information of all modules on the specified channel (loghost in this
example). Then configure the output rule as needed so that unnecessary information will not be output.
# Configure the information output rule. Allow log information of all modules with severity equal to or
more severe than informational to be output to the log host.
[Sysname] info-center source default channel loghost log level informational state on
Configure the log host
Step 1: Log in to the log host as a root user.
Step 2: Create a subdirectory named Device under directory /var/log/, and create file info.log under
the Device directory to save logs of Device.
# mkdir /var/log/Device
# touch /var/log/Device/info.log
Step 3: Edit file /etc/syslog.conf and add the following contents.
