# mkdir /var/log/Quidway
# touch /var/log/Quidway/information
Step 2: Edit the file “/etc/syslog.conf” as the superuser (root user) to add the following
selector/action pair.
# Quidway configuration messages
local4.info /var/log/Quidway/information
Note:
When you edit the file “/etc/syslog.conf”, note that:
z A note must start in a new line following a “#” sign.
z In each pair, a tab should be used as a separator instead of a space.
z No space is allowed at the end of a file name.
z 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
147
# kill -HUP 147
After all the above operations, the switch can make records in the corresponding log
file.
Note:
Through combined configuration of the device name (facility), information severity level
threshold (severity), module name (filter) and file “syslog.conf”, you can sort
information precisely for filtering.

address is 202.38.1.10: All modules' log information, with severity higher than “errors”.
