This command can be used for filtering of log, trap or debugging information. For example, it can control information output from the IP module to any direction. You can configure to output information with severity higher than “warning” to the log host, and information with severity higher than “informational” to the log buffer, and configure to output trap information to the log host at the same time.
The info-center source command determines the output direction according to channel name or channel number. Each output direction is assigned with a default information channel, as shown in Table 1-3.
Table 1-3 Default information channel

Additionally, each information channel is configured with a default configuration record, whose module name is default and module number is 0xffff0000. However, its default settings for log, trap and debugging information may differ with channels. If no configuration record is configured for a channel, the default configuration record is adopted.

info-center synchronous
Syntax
info-center synchronous
undo info-center synchronous
View
System view
Parameters
None
Description
Use the info-center synchronous command to enable synchronous information output, so that if system information (such as log information) is output when the user is inputting information, the command prompt and the 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 information output.
By default, the synchronous information output function is disabled.
l The synchronous information output function is used in the case that your input is interrupted by a large amount of system output. With this function enabled, the system echoes your previous input and you can continue your operations from where you were stopped.
l Running the info-center synchronous command during debugging information collection may result in a command prompt echoed after each item of debugging information. To avoid unnecessary output, it is recommended to disable synchronous information output in such case.
