Description
Use the info-center source command to specify the information source in the information center and the output direction.
Use the undo info-center source command to cancel the configured information source and output direction.
This command can be used for filtering log, trap or debugging information. For example, it can control information output from the IP module to a self-defined direction. You can configure to output information with a severity higher than “warning” to the log host, and information with a severity higher than “informational” to the log buffer. You can also configure to output trap information to the log host at the same time.
The info-center source command determines the output direction according to a channel name or channel number. Each output direction is assigned a default information channel at present, as shown in the following table.

In addition, each information channel has a default record with a module name of “default” and a module number of 0xffff0000. However, for different information channels, the default log, trap and debugging settings in the records may be different from one another. Use the default configuration record if a module does not have any explicit configuration record in the channel.
