35.6 Debug

All the protocols switch supports have their corresponding debug commands. The users can use the
information from debug commands for troubleshooting. Debug commands for their corresponding protocols
will be introduced in the later chapters.

35.7 System log

35.7.1 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.
35.7.1.1 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
Display the operation information and the state
of each task running on the switch. It is used by
the technicians to diagnose whether the switch
operates properly.
