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 debug program, it provides powerful support for
network administrators and developers in network operation monitoring and fault
diagnosis.
Information items are presented in the following format:
<priority>timestamp sysname module/level/digest:content
Here, angle brackets “<>”, spaces, slashes “/” and colon are valid and required.
Below is an example of log output to a log host:
<188>Apr 9 17:28:50 2004 Quidway S6502 IFNET/5/UPDOWN:Line protocol on the
interface M-Ethernet0/0/0 is UP (SIP=10.5.1.5 ,SP=1080)
The following describes the fields contained in 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 data type of the time stamp field contained in log information sent to the log host is
date, whose format is Mmm dd hh:mm:ss 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 yyyy” 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, and “yyyy” is the year.
Note that a space separates the time stamp and host name.
3) Host name
It refers to the system name of the host, which is “Quidway” by default.
You can modify the host name with the sysname command in system view.
