Chapter 1 Information Center

1.1 Information Center Overview

Information center is an indispensable part of Ethernet switches and exists as an
information hub of system software modules. The information center manages most
information outputs; it sorts information carefully, and hence can screen information in
an efficient way. Combined with the debugging program (debugging commands), it
provides powerful support for network administrators and developers in network
operation monitoring and fault diagnosis.
Information items output by S3900 series switches are presented in the following
format:
<priority>timestamp sysname module/level/digest:content
Here, angle brackets "<>", spaces, slashes "/" and colon are the fixed format of
information.
Below is an example of log output to a log host:
<188>Apr
interface M-Ethernet0/0/0 is UP
The following describes the fields in front of the content field of an information item:
1) Priority
The calculation formula for priority is priority = facility × 8 + severity – 1. For VRP, the
default facility value is 23 and severity ranges from one to eight. See Table 1-2 for
description of severity levels.
Note that no character is permitted between the priority and time stamp. The priority
takes effect only when the information is sent to the log host.
2) Time stamp
The time stamp sent to the log host is in the format of Mmm dd hh:mm:ss:ms yyyy,
where:
"Mmm" represents the month, and the available values are: Jan, Feb, Mar, Apr, May,
Jun, Jul, Aug, Sep, Oct, Nov and Dec.
"dd" is the date, which shall follow a space if less than 10, for example, " 7".
"hh:mm:ss:ms" is the local time, where "hh" is in the 24-hour format, ranging from 00 to
23, both "mm" and "ss" range from 00 to 59, "ms" ranges from 000 to 999, and "yyyy" is
the year.
Note that a space separates the time stamp and host name.
3) Host name
