NFORMATION
The information center is an indispensable part of the switch. It serves as an
information center of the system software modules. The logging system is
responsible for most of the information outputs, and it also makes detailed
classification to filter the information efficiently. Coupled with the debugging
program, the information center provides powerful support for the network
administrators and the R&D personnel to monitor the operating status of
networks and diagnose network failures.
When the log information is output to terminal or log buffer, the following parts
will be included:
% <priority> Timestamp Sysname Module name/Severity/Digest: Content
For example:
%Jun 7 05:22:03 2003 3Com IFNET/6/UPDOWN:Line protocol on interface
Ethernet2/1/2, changed state to UP
When the log information is output to information center, the first part will be
"<Priority>".
For example:
% <189>Jun 7 05:22:03 2003 3Com IFNET/6/UPDOWN:Line protocol on interface
Ethernet0/0/0, changed state to UP
The description of the components of log information is as follows:
1 %
In practical output, some of the information is started with the % character, which
means a logging is necessary.
2 Priority
The priority is computed according to following formula: facility*8+severity-1. The
default value for the facility is 23. The range of severity is 1~8, and the severity will
be introduced in separate section.
Priority is only effective when information is send to log host. There is no character
between priority and timestamp.
