Start learning cybersecurity with CBT Nuggets. https://courses.cbt.gg/security

In this video, Jeremy Cioara covers how to configure SPAN and RSPAN on a Cisco switch. He begins with a brief overview of how switches are designed to work, then gives examples of why a network administrator might want to step outside of that construct and how to do so.

Jeremy starts the video with an outline of how switches work and why exceptions sometimes need to be made. Switch port analyzer sessions and remote sessions are key resources for network administrators to be able to see inside of a switch and analyze what’s actually happening. You can do this regardless of whether data is being sent, received, or both simultaneously. This video will walk you through the basic theory behind why monitoring sessions are necessary. Jeremy will also demonstrate a step-by-step example of how to configure a Cisco switch for both SPAN and RSPAN, as well as examples for when each approach is appropriate.
