1-17When you edit the file “/etc/syslog.conf”, note that:z A note must start in a new line, starting with 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 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 thecommands info-center loghost and info-center source. Otherwise, log information may not beoutput to the log host normally.Step 3: After the log file “information” is created and the file “/etc/syslog.conf” is modified, execute thefollowing command to send a HUP signal to the system daemon “syslogd”, so that it can reread itsconfiguration file “/etc/syslog.conf”.# ps -ae | grep syslogd147# kill -HUP 147After all the above operations, the switch can make records in the corresponding log file.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.Log Output to a Linux Log HostNetwork requirementsThe switch sends the following log information to the Linux log host whose IP address is 202.38.1.10:All modules' log information, with severity higher than “errors”.Network diagramFigure 1-2 Network diagram for log output to a Linux log hostConfiguration procedure1) Configure the switch:# Enable the information center.
