determines the output direction according to channel name or channel number. Each
output direction is assigned with a default information channel at present, as
shown in Table 1-3.

Each information channel is configured with
a default record, whose module name is “default” and module number
is 0xffff0000. In the record, the default settings for log, trap and debug
information may differ with channels. If no record is configured for a channel,

Parameter
None
Description
Use the info-center synchronous command
to enable synchronous terminal output, so that if system information (such as
log information) is output when the user is inputting, the command prompt and
input information are echoed after the output (note that, the command prompt is
echoed in command edit state but is not echoed in interactive state).
Use the undo info-center synchronous
command to disable synchronous terminal output.
By default, the synchronous terminal output
function is disabled.
l
By enabling the synchronous terminal output
function with the info-center synchronous command, you can avoid
users’ input from being interrupted by system information output.
l
Running the info-center synchronous command
during debug information collection may result in a command prompt echoed after
each item of debug information. To avoid unnecessary output, it is recommended
that you disable synchronous terminal output in such cases.
