Step 1: Execute the following commands as the super user (root user).
# mkdir /var/log/Switch
# touch /var/log/Switch/information
Step 2: Edit the file "/etc/syslog.conf" as the super user (root user) to add the
following selector/action pairs.

When you edit the file "/etc/syslog.conf", note that:
■
A note must start in a new line, starting with a "#" sign.
■
In each pair, a tab should be used as a separator instead of a space.
■
No space is allowed at the end of a file name.

The device name (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, execute the following command to send a HUP signal to the system
daemon "syslogd", so that it can reread its configuration file "/etc/syslog.conf".

After all the above operations, the switch can make records in the corresponding

Through combined configuration of the device name (facility), information severity
level threshold (severity), module name (filter) and the file "syslog.conf", you can
sort information precisely for filtering.
