Information introduction
As an information hub of a router, the information center manages most of
information output and makes careful classification for efficient information
filtering.
The information center of the system has the following features:
The information center provides three types of information, that is, log, trap and
debug.
The information is divided into eight levels in terms of severity, namely,
emergencies, alerts, critical, errors, warnings, notifications, informational and
debugging.
The system supports ten channels. The first six channels (Channel 0 to Channel 5)
have their default channel names,
The information center can output information in six directions: console, Telnet
terminal and monitor, logbuffer, loghost, trapbuffer and SNMP.
