Refer to the following: Logging Console 7 Which option is one of the effects entering this command on a Cisco IOS router, with no additional logging configuration?
正解:B
Explanation/Reference: Explanation: Console logging: By default, the router sends all log messages to its console port. Hence only the users that are physically connected to the router console port can view these messages. The router does not check if a user is logged into the console port or a device is attached to it; if console logging is enabled, messages are always sent to the console port that can cause CPU load. To stop the console logging, use the "no logging console" global configuration command. You might want to limit the amount of messages sent to the console with the "logging console level" configuration command (for example, logging console Informational).
