This chapter describes the use of the Ethernet Automatic Protection Switching (EAPS ™ ) protocol, and
includes information on the following topics:
• Overview of the EAPS Protocol on page 143
• Summit 200 Series Switches in Multi-ring Topologies on page 147
• Commands for Configuring and Monitoring EAPS on page 148
Overview of the EAPS Protocol
The EAPS protocol provides fast protection switching to Layer 2 switches interconnected in an Ethernet
ring topology, such as a Metropolitan Area Network (MAN) or large campuses (see Figure 25).
