Syslog Overview The 3Com Router 1.x is configured with Syslog (log system). As an indispensable part of the 3Com Router 1.x, Syslog serves as the information junction of the 3Com Router 1.x system software module. The log system is responsible for most of the information output and can perform detailed classification so as to filter information effectively. In combination with the debugging command, the system provides powerful support for the network administrator and development staff to monitor the network running state and diagnose the network faults.

The Syslog of the 3Com Router 1.x features the following:

■Support log output in four directions, i.e. to the control console (Console), to the telnet terminal and the dumb terminal (Monitor), to the internal buffer (Buffer), and to the log host (Loghost).

■Log information is divided into eight levels according to the importance and filter based on the levels.

■Information is classified according to the source modules and filter based on the modules.

■Information can be output in Chinese or English.

Configure Syslog The configuration tasks of Syslog include:

■Set the direction of Syslog outputting log information

■Set the Severity of log information

■Set the Filter of log information

■Turn on/off Syslog
