Configuration procedure
Before configuration, make sure that there is a route between Device and PC.
1 Configuring the device
# Enable information center.
<Sysname> system-view
[Sysname] info-center enable
# Specify the host with IP address 1.2.0.1/16 as the log host, use channel loghost
to output log information (optional, loghost by default), and specify local5 as the
logging facility.
[Sysname] info-center loghost 1.2.0.1 channel loghost facility local5
# Disable the output of log, trap, and debugging information of all modules on
the channel loghost.
c
CAUTION: 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 (loghost 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 all modules with
severity equal to or higher than informational to be output to the log host.
