Operation Manual – Information Center
H3C S3100 Series Ethernet Switches
Note:
The space, the forward slash /, and the colon are all required in the above format.
Before <timestamp> may have %, "#, or * followed with a space, indicating log,
alarm, or debugging information respectively.
Below is an example of the format of log information to be output to a monitor terminal:
%Dec
6 10:44:55:283 2006 Sysname NTP/5/NTP_LOG:- 1 - NTP service enable
("-1-" indicates that the unit number of the device is 1.)
If the output destination is loghost, the switch and the log host use the syslog
protocol. The system information is in the following format according to RFC 3164
(The BSD Syslog Protocol):
<Int_16>timestamp sysname %%nnmodule/level/digest: source content
Note:
If the address of the log host is specified in the information center of the switch,
when logs are generated, the switch sends the logs to the log host in the above
format. For detailed information, refer to
Log
Host.
There is the syslog process on the Unix or Linux platform, you can start the process
to receive the logs sent from the switch; in the Windows platform, you need to install
the specific software, and it will operate as the syslog host.
Some log host software will resolve the received information as well as its format, so
that the log format displayed on the log host is different from the one described in
this manual.
What follows is a detailed explanation of the information fields involved:
I. Int_16 (Priority)
The priority is calculated using the following formula: facility*8+severity-1, in which
facility (the device name) defaults to local7 with the value being 23 (the value of
local6 is 22, that of local5 is 21, and so on).
severity (the information level) ranges from 1 to 8.
meaning associated with each severity.
Note that the priority field appears only when the information has been sent to the log
host.
