What is the effect of the logging trap debug command on syslog messages?

The logging trap debug command configures the router to send syslog messages of all severity levels (0-7) to the configured syslog server. The debug keyword corresponds to severity level 7, which is the lowest severity, meaning it includes all higher severity levels as well. This ensures that every message generated by the device, regardless of its importance, is forwarded to the syslog server for monitoring and analysis. "Sends messages with lower severity levels to the syslog server" is partially correct but not comprehensive enough, as debug includes all levels. "Sends messages of severity Warning, Error, Critical, and Emergency to the syslog server" is incorrect because this command includes all severities, not just these specific ones. "Stops sending messages to the syslog server" is the opposite of the command's function.
