Chapter 2. Implementing Data Center Switching Protocols
Switching is an OSI Layer 2 (L2) process that uses a device’s Media Access Control (MAC) address to perform forwarding decisions. For high availability, switches are normally interconnected using redundant links. Switching protocols prevent Layer 2 looping when deploying switches with redundant links.
This chapter covers the following key topics:
Spanning Tree Protocols (STP): This section provides an overview of the Layer 2 Spanning Tree Protocol, discusses the Rapid PVST+ protocol, and includes a configuration example.
Port Channels: This section discusses the Layer 2 port channel and command-line interface (CLI) commands and includes a configuration example
Virtual Port Channel: This ...
