MicroNugget: How to Configure SPAN and RSPAN on a Cisco Switch

Description:

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 explains why a network administrator might want to step outside of that construct and how to do so. Switch port analyzer sessions and remote sessions are key resources for network administrators to see inside a switch and analyze what’s actually happening, regardless of whether data is being sent, received, or both simultaneously. This video walks through the basic theory behind why monitoring sessions are necessary and demonstrates a step-by-step example of configuring a Cisco switch for both SPAN and RSPAN, including examples of when each approach is appropriate.
