The name can be channel6, channel7, channel8, channel9, console, logbuffer, loghost, monitor, snmpagent, trapbuffer. state: Set the state of the information. state: Specify the state as on or off. Description Use the info-center source command to add/delete a record to the information channel. Use the undo info-center source command to delete the contents of the information channel. For example, for the filter of IP module log output, you can configure to output the logs at a level higher than warnings to the log host and output those higher than informational to the log buffer. You can also configure to output the trap information on the IP module to a specified trap host, etc. The channels for filtering in all the directions are specified by this configuration command. All the information will be sent to the corresponding directions through the specified channels. You can configure the channels in the output direction, channel filter information, filtering and redirecting of all kinds of information. At present, the system distributes an information channel in each output direction by default, shown as follows: Table 57 Information Channel in Each Output Direction by Default Output direction Console Monitor Info-center loghost Log buffer Trap buffer snmp Information channel name console monitor loghost logbuffer trapbuffer snmpagent In addition, each information channel has a default record with the module name "default" and module number as 0xffff0000. However, for different information channel, the default log, trap and debugging settings in the records may be different with one another. Use default configuration record if a module does not have any specific configuration record in the channel.
