z⁄VM Education - Unit 09 - Virtual Switch - The Basics

The Virtual Switch (VSwitch) is a virtualized representation of a hardware LAN switch. A virtual switch is capable of bridging a z/VM guest LAN to an associated real LAN connected by an OSA-Express adapter. This video reviews some z/VM networking basics, and then discusses more intermediate topics regarding z/VM Virtual Networking and the Virtual Switch.
