To sum up, the major task of the information center is to output the three types of information of the
modules onto the ten channels in terms of the eight severity levels and according to the user’s settings,
and then redirect the system information from the ten channels to the six output directions.
System Information Format
The format of system information varies with the output destinations.
z If the output destination is console, monitor terminal, logbuffer, trapbuffer, or SNMP, the system
information is in the following format:
timestamp sysname module/level/digest: - unitid –content
z The space, the forward slash /, and the colon are all required in the above format.
z Before <timestamp> may have %, “#, or * followed with a space, indicating log, alarm, or debugging

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.)
z 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
