1-17Note the following items when you edit file “/etc/syslog.conf”.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 permitted at the end of the file name.z The device name (facility) and received log information severity specified in file “/etc/syslog.conf”must be the same with those corresponding parameters configured in commands info-centerloghost and info-center source. Otherwise, log information may not be output to the log hostnormally.Step 3: After the log file “information” is created and the file “/etc/syslog.conf” is modified, execute thefollowing commands to view the process ID of the system daemon “syslogd”, stop the process, and thenrestart the daemon "syslogd" in the background with the “-r” option.# ps -ae | grep syslogd147# kill -9 147# syslogd -r &In case of Linux log host, the daemon “syslogd” must be started with the “-r” option.After all the above operations, the device can record information 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 the ConsoleNetwork requirementsAs shown in Figure 1-3, Switch sends the following information to the console: the log information of thetwo modules ARP and IP, with severity higher than “informational”.Figure 1-3 Network diagram for log output to the consolePCConsoleSwitchConfiguration procedure# Enable the information center. system-view
