state state: Configures whether to output the system information. The value of state can be on (enabled) or off (disabled).
Description
Use the info-center source command to specify the output rules of the system information.
Use the undo info-center source command to remove the specified output rules.
By default, the output rules for the system information are listed in Table 1-4.
This command can be used to set the filter and redirection rules of log, trap and debugging information.
For example, the user can set to output log information with severity higher than warnings to the log host, and information with severity higher than informational to the log buffer. The user can also set to output trap information of the IP module to a specified output destination.
Note that:
l If you do not use the module-name argument to set output rules for a module, the module uses the default output rules or the output rules set by the default keyword; otherwise, the module uses the output rules separately set for it.
l If you use the module-name argument to set the output rules for a module without specifying the debug, log, and trap keywords, the default output rules for the module are as follows: the output of log and trap information is enabled, with severity being informational; the output of debugging information is disabled, with severity being debugging. For example, if you execute the command info-center source snmp channel 5, the command is actually equal to the command info-center source snmp channel 5 debug level debugging state off log level informational state on trap level informational state on.
l After you separately set the output rules for a module, you must use the module-name argument to modify or remove the rules. The new configuration by using the default keyword is invalid on the module.
l You can configure to output the log, trap and debugging information to the trap buffer, but the trap buffer only receives the trap information and discards the log and debugging information.
l You can configure to output the log, trap and debugging information to the log buffer, but the log buffer only receives the log and debugging information and discards the trap information.
l You can configure to output the log, trap and debugging information to the SNMP module, but the SNMP module only receives the trap information and discards the log and debugging information.

info-center synchronous
Syntax
info-center synchronous
undo info-center synchronous
View
System view
Parameter
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.
Example
# Enable synchronous information output.
<Sysname> system-view
