The process is repeated until the packet reaches the destination. The process is to
record the source address of each ICMP TTL timeout message to provide the route

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:
■ Enabling and Disabling the Logging Function
■ Setting the Output Channel of the Log
■ Defining the Log Filtering Rules
■ Configuring the SNMP Timestamp Output Format
■ Displaying and Debugging the Syslog Function
For the above configuration, the log host is not configured on the switch. All other
configurations will take effect after enabling the logging function.
