Logging Function
The syslog characterizes the behavior of the Switch 8800. It serves as an 
information center of the system software modules. The logging system is 
responsible for most of the information output, and also to make detailed 
classification to filter the information efficiently. Coupled with the debugging 
program, the syslog provides powerful support for the network administrators to 
monitor the operational state of networks and to diagnose network failures.
The syslog of the Switch 8800 has the following features:
Support for six different output destinations: console, monitor to Telnet 
terminal, log buffer, loghost, trap buffer, and SNMP. 
The log is divided into 8 levels according to the significance of the event, and it 
can be filtered based on the levels. 
The information can be classified in terms of the source modules, and the 
information can be filtered by module.
The output language can be selected between English and Chinese.
SYSLOG configuration includes tasks described in the following sections:
For the above configuration, the log host is not configured on the switch. All other 
configurations will take effect after enabling the logging function.
