264CHAPTER 11: SYSTEM MANAGEMENT

Configuring the Info-center Loghost

This configuration is performed on the info-center loghost. The following configuration example is implemented on SunOS 4.0. The configurations on the Unix operating systems of other vendors are similar.

1Perform the following commands with the identity of root

mkdir /var/log/SW7750

touch /var/log/SW7750/config

touch /var/log/SW7750/security

2Edit the file “/etc/syslog.conf” with the identity of root and add the following selector/action pairs.

SW7750 configuration messages:

Local4.crit /var/log/SW7750/config

SW7750 security messages:

local5.notice /var/log/SW7750/security

Pay attention to the following points when editing the file “/etc/syslog.conf”:

The description must start from a fresh line and begin with a pound key #.

Use tab character to separate the selectors/action pairs instead of space.

No redundant spaces should be left behind the name of the file.

3When the log files “config” and “security” are created, and the file “/etc/syslog.conf” is modified, perform the following commands to send a HUP signal to the system demon syslogd, so that the syslogd can read the configuration file “/etc/syslog.conf” again.

ps -ae grep syslogd 147

kill -HUP 147

After the operations are performed, the system can record information in the corresponding logging files

Configuring the facility, severity, filter and the file “syslog.conf” integrally makes it possible to perform the detailed classification for the purpose of information filtering.

If you are using a UNIX workstation as a syslog server, consult your UNIX system manager manual for syslog configuration information.

Example: Log Configuration

Configure to output log on the console, as follows:

1Enable the logging system.

[SW7750]info-center enable

2Configure the logging output of the console and allows the log output of RSTP module with the severity ranged from “emergencies” to “debugging”.

[SW7750]info-center console channel console

[SW7750]info-center source rstp channel 6 log level debugging

3Enable RSTP module debugging.

<SW7750>debugging rstp all
