Information
Verify logging to device console is enabled and limited to a rational severity level to avoid impacting system performance and management.
Rationale:
This configuration determines the severity of messages that will generate console messages. Logging to console should be limited only to those messages required for immediate troubleshooting while logged into the device. This form of logging is not persistent; messages printed to the console are not stored by the router. Console logging is handy for operators when they use the console.
Solution
Configure console logging level.
hostname(config)#logging console critical
Impact:
Logging critical messages at the console is important for an organization managing technology risk. The 'logging console' command should capture appropriate severity messages to be effective.
Default Value:
The default is to log all messages
Notes:
The console is a slow display device. In message storms some logging messages may be silently dropped when the console queue becomes full. Set severity levels accordingly.
