Information filtering by severity works this way: information with the severity value greater than the
configured threshold is not output during the filtering.
z
If the threshold is set to 1, only information with the severity being emergencies will be output;
z
If the threshold is set to 8, information of all severities will be output.
Ten channels and six output destinations of system information
The system supports six information output destinations, including the Console, Monitor terminal
(monitor), logbuffer, loghost, trapbuffer and SNMP.
The system supports ten channels. The channels 0 through 5 have their default channel names and are
associated with six output destinations by default. Both the channel names and the associations
between the channels and output destinations can be changed through commands.
