Severity Severity value Description
informational 7 Informational information to be recorded
debugging 8 Information generated during debugging
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 directions of system information
The system supports six information output directions, 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 directions by default. Both the channel names and the associations between
the channels and output directions can be changed through commands.
