Information filtering by severity works this way: information with the severity value
greater than the configured threshold is not output during the filtering.
If the threshold is set to 0, only information with the severity being emergencies will
be output;
If the threshold is set to 7, information of all severities will be output.
III. Ten channels and seven output destinations of system information
The system supports seven information output destinations, including the Console,
console terminal (monitor), logbuffer, loghost, trapbuffer, SNMP and logfile.
The system supports ten channels. The channels 0 through 5, and channel 9 have their
default channel names and are associated with seven output destinations by default.
Both the channel names and the associations between the channels and output
destinations can be changed through commands.
