Access Switch Port Redundancy Standards
In this tech paper, you will learn about the key protocols for building a redundant network and discover—based on five examples—how to design highly available three-tier or two-tier networks using LANCOM products. This paper is part of the series “switching solutions“. Resilient Ethernet Protocol (REP) is a Cisco proprietary protocol that provides an alternative to the Spanning Tree Protocol (STP) to control network loops, handle link failures, and improve convergence time. REP provides a basis for constructing more. Ethernet switch port types define the performance, scalability, and architecture of modern networks. RJ45 ports serve access-layer copper connections; SFP/SFP+ ports enable flexible 1G/10G uplinks; SFP28 delivers 25G for modern data centers; QSFP+ and QSFP28 support high-density 40G/100G spine–leaf. The WAN connectivity is pretty solid with dual-ISPs at each location connected to 2 44XX ISR Routers with HSRP redundancy. Ethernet networks rely on this flood-and-learn behavior to work.
