How do you use SPAN and RSPAN to manage network traffic?
While this question could stand alone, it may also be a follow-up to a previous question asking about the tools you use to manage network traffic. Interviewers will ask follow-up questions immediately after the initial question or later in the interview. If asked immediately, they want more information about the topic. If asked later in the interview, the interviewer is looking to confirm that you're consistent in your answers during the interview. In either case, answering factually and truthfully will provide the interviewer with the information they seek and confirm that your answers are consistent.
"SPAN, which stands for Switched Port Analyzer, and RSPAN, which is Remote Switched Port Analyzer, are both tools that enable me to monitor traffic flowing from one port to another. The tools copy ethernet frames passing through switch ports. SPAN and RSPAN don't analyze these copied frames; they send frames from a specific port to a network analyzer. I use these tools to help analyze and measure traffic on the net and make any adjustments to increase the performance."
