Chapter 1 Information Center Configuration

1.1 Information Center Overview

1.1.1 Introduction to Information Center

Acting as the system information hub, information center classifies and manages

system information. Together with the debugging functionality, information center offers

a powerful support to the network administrators and developers in monitoring network

performance and diagnosing network problems.

1.1.2 System Information Format

System information has the following format:

<priority>timestamp sysname module/level/digest:content

Note:

zThe closing set of angel brackets < >, the space, the forward slash /, and the colon

are all required in the above format.

zBefore the <priority> may have %, “#, or * followed with a space, indicating log,

alarm, or debug information respectively.

Below is the format of log information to be output to a log host:

% <188>Sep 28 15:33:46:235 2005 Sysname SHELL/5/LOGIN: Console login from con0

What follows is a detailed explanation of the fields involved:

I. Priority

The priority is calculated using the following formula: facility*8+severity-1, in which

facility is local7 by default and the range of severity is 0 to 7. Table 1-2 details the value

and meaning associated with each severity.

Note that there is no space between the priority and timestamp fields and that the

priority only takes effect when the information has been sent to the log host.

II. Timestamp

Timestamp records the time when system information is generated to allow users

check and identify system events.

Note that there is a space between the timestamp and sysname (host name) fields.

Operation Manual – Information Center

H3C S5500-SI Series Ethernet Switches Chapter 1 Information Center Configuration

1-2

III. Sysname

Sysname is the system name of the current host. Users can use the sysname

command to modify the sysname.

Note that there is a space between the sysname and module fields.

IV. Module

The module field represents the name of the module that generates system information.

Some modules are shown below:

UDPH UDP Helper module

VFS Virtual File module

VTY Virtual Type Terminal module

default Default setting of all modules

Between “module” and “level” is a “/”.

V. Level (Severity)

System information falls into three categories: log information, debug information, and

trap information. Each kind of information can be further divided into eight levels based

on its severity, as detailed in Table 1-2. Note that the smaller the severity value, the

higher the severity.

Table 1-2 Severity description

Severity Severity Value Description

emergencies 0 The most emergent errors

alerts 1 Errors that demand

prompt correction

critical 2 Critical errors

errors 3 Errors that are not critical

but demand attention

warnings 4 Warnings that suggest

possible errors

notifications 5 Normal errors with

important prompts

Operation Manual – Information Center

H3C S5500-SI Series Ethernet Switches Chapter 1 Information Center Configuration

1-4

Severity Severity Value Description

informational 6 Normal prompts

debugging 7 Debugging prompts

Information filtering by severity works this way: information with severity value greater

than the configured threshold will not be output during the filtering.

zIf the threshold is set to 0, only information with the severity being emergencies will

be output;

zIf the threshold is set to 7, information of all severities will be output.

Note that there is a forward slash between the levels (severity) and digest fields.

VI. Digest

The digest field is a string of up to 32 characters, outlining the system information.

Note that there is a colon between the digest and content fields.

VII. Content

This field provides the content of the system information.

1.2 Configuring Information Center

Information center has the following characteristics:

zSupports information output to the console, the monitor, the log host, the trap

buffer, the log buffer, and the SNMP agent (snmpagent). A default channel is

allocated to each individual output direction, as illustrated in the following table.

zSystem information is classified into eight categories according to severity and

filtered by severity;

zSystem information is categorized and filtered by source module;

zThe output information can be in English or Chinese.

Table 1-3 Information channels for different output directions

Output direction Information channel No. Default channel name

Console 0 console

Monitor terminal 1 monitor

Log host 2 loghost

Trap buffer 3 trapbuffer

Log buffer 4 logbuffer

SNMP NMS 5 snmpagent

Note:

Configurations for the six output directions function independently and take effect only

after the information center has been enabled.
