3Com Switch 4200G Configuration Guide

Information Center Configuration 345
Information Center
Configuration
The switch supports information output to six directions.
By far, each output direction is assigned with an information channel, as shown in
Table 297.
Settings for the six output directions are independent. However, for any output
direction, you must first enable the information center to make all other settings
effective.
Information center of the Ethernet switch features:
■ Supporting six information output directions, namely, console (console), monitor
terminal (monitor), log host (loghost), trap buffer (trapbuffer), log buffer
(logbuffer) and SNMP (snmpagent),
■ Filtering information by information severities (information is divided into eight
severity levels),
■ Filtering information by modules where information is generated,
■ Language options (Chinese or English) for information output.
Enabling Synchronous
Terminal Output
To avoid user’s input from being interrupted by system information output, you can
enable the synchronous terminal output function, which echoes user's input after
each system output. This makes users work with ease, for they no longer worry about
losing uncompleted inputs.
Running the info-center synchronous command during debug information
collection may result in a command prompt echoed after each item of debug
information. To avoid unnecessary output, it is recommended that you disable
synchronous terminal output in such cases.
