This section contains information on the Logging function.
The Info-center 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 info-center provides powerful support for network administrators and
support personnel to monitor the operating state of networks and diagnose network
failures.
When the log information is output to terminal or log buffer, the following parts will
be included:
%Timestamp Sysname Module name/Severity/Digest: Content
For example:
%Jun 7 05:22:03 2003 SW5500 IFNET/6/UPDOWN:Line protocol on interface
Ethernet1/0/2, changed state to UP
When the log information is output to the info-center, the first part will be
" ".
<Priority>
For example:
<187>Jun 7 05:22:03 2003 SW5500 IFNET/6/UPDOWN:Line protocol on
interface Ethernet1/0/2, changed state to UP
The description of the components of log information is as follows:
1 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 a separate section.
The value of the facility can be set by command
local7 corresponding to 16 to 23 respectively, for detailed information, refer to
RFC3164 (The BSD syslog Protocol).
Priority is only effective when information is send to loghost. There is no character
between priority and timestamp.
2 Timestamp
If the logging information is sent to the log host, the default format of the timestamp
is the date, and it can be changed to
command:
info-center timestamp log { date | boot | none }
The date format of timestamp is "
" " is the month field, such as: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov,
mm
Dec.
" " is the day field, if the day is less than the 10th, one blank should be added, such
