■ The facility and received log information severity level specified in the file
"/etc/syslog.conf" must be the same as those corresponding parameters
configured in the commands info-center loghost and info-center source.
Otherwise, log information may not be output to the log host normally.
Step 3: After the log file "information" is created and the file "/etc/syslog.conf" is
modified, run the following command to send a HUP signal to the system daemon
"syslogd", so that it reads its new configuration file "/etc/syslog.conf".
# ps -ae | grep syslogd

# kill -HUP 147
After all the above operations, the switch can make records in the corresponding
log file.
