Teaser of Lecture 19. What is ERSPAN Port Mirroring in VMware Distributed Switch: ESXi Networking

In this advanced VMware networking lecture, we dive into ERSPAN (Encapsulated Remote Switch Port Analyzer) Port Mirroring within VMware's Distributed Switch (vDS). ERSPAN allows you to monitor and capture traffic remotely by mirroring packets from a set of distributed ports to a remote agent IP address over an IP tunnel.

Key Topics Covered:
• Introduction to ERSPAN Port Mirroring and its benefits.
• VMware Distributed Switch (vDS) Configuration Overview.
• Step-by-step guide to configuring ERSPAN on VMware vDS.
• Capturing and analyzing traffic using ERSPAN.
• How GRE tunnels encapsulate traffic for remote monitoring.
• Validating traffic mirroring between distributed ports and a remote destination.
