Be aware of the following issues while editing file /etc/syslog.conf:
z Comments must be on a separate line and begin with the # sign.
z No redundant spaces are allowed after the file name.
z The logging facility name and the information level specified in the /etc/syslog.conf file
must be identical to those configured on the device using the info-center loghost and
info-center source commands; otherwise the log information may not be output properly
to the log host.
Step 4: After log file info.log is created and file /etc/syslog.conf is modified, you need to issue
the following commands to display the process ID of syslogd, kill the syslogd process and
then restart syslogd using the –r option to make the modified configuration take effect.
# ps -ae | grep syslogd
147
# kill -HUP 147
# syslogd -r &
After the above configurations, the system will be able to record log information into the log file.

Configuration procedure
Before the configuration, make sure that there is a route between Device and PC.
1) Configure the device
# Enable information center.
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 use 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 channel loghost.
