76.7 System log

76.7.1 System Log Introduction

The system log takes all information output under it control, while making detailed catalogue, so to select the

information effectively. Combining with Debug programs, it will provide a powerful support to the network

administrator and developer in monitoring the network operation state and locating the network failures.

The switch system log has following characteristics

 Log output from four directions (or log channels) of the Console, Telnet terminal and monitor, log

buffer zone, and log host.

 The log information is classified to four level of severities by which the information will be filtered

 According to the severity level the log information can be auto outputted to corresponding log

channel.

76.7.1.1 Log Output Channel

So far the system log can be outputted the log information through four channels:

 Through Console port to the local console

 Output the log information to remote Telnet terminal or monitor, this function is good for remote

maintenance

 Assign a proper log buffer zone inside the switch, for record the log information permanently or

temporarily

 Configure the log host, the log system will directly send the log information to the log host, and

save it in files to be viewed at any time

Among above log channels, users rarely use the console monitor, but will commonly choose the Telnet

terminal to monitor the system operation status. However information outputted from these channels are of

low traffic capacity and can not be recorded for later view. The other two channels---the log buffer zone and

log host channel are two important channels
