Introduction April 2014

In environments where multiple distribution layer switches exist in close proximity and where fiber optics provide

the ability for high-bandwidth interconnect, a core layer reduces the network complexity, as shown in the

following two figures.

The core layer of the LAN is a critical part of the scalable network, and yet it is one of the simplest by design.

The distribution layer provides the fault and control domains, and the core represents the 24x7x365 nonstop

connectivity between them, which organizations must have in the present business environment where

connectivity to resources to conduct business is critical.

In the campus core-layer design where Cisco Catalyst 6800 or 6500 Series Switches are used, a Catalyst

VSS Layer-3 core design is chosen as the preferred alternative to traditional designs, which often use two

independently configured and managed platforms. Connectivity to and from the core is Layer 3 only, which

drives increased resiliency and stability.

For an in-depth VSS configuration guide and configuration options, go to

www.cisco.com/go/cvd/campus and, on the Cisco Validated Designs tab, look for the

Campus 3.0 Virtual Switching System Design Guide.
