will output all the information.
Definition of severity in logging information is as follows.

Configuration
The Switch supports five output directions of information.
The system assigns a channel in each output direction by default. See the table
below.
Table 280 Numbers and Names of the Channels for Log Output
The settings in the six directions are independent from each other. The settings will
take effect only after enabling the information center.
The Switch info-center has the following features:
■ Support to output log in five directions, that is, console, monitor to Telnet
terminal, logbuffer, trapbuffer, and SNMP.
■ The log is divided into eight levels according to the significance and it can be
filtered based on the levels.
