Introduction

The Campus Wired LAN Technology Design Guide describes how to design a wired network access with

ubiquitous capabilities that scale from small environments (for instance, those environments with one to just a

few LAN switches) to a large, campus-size LAN. Resiliency, security, and scalability are included to provide a

robust communications environment. Quality of Service (QoS) is integrated to ensure the base architecture can

support a multitude of applications including low latency, drop-sensitive multimedia applications, that coexist with

data applications on a single network.

The campus LAN architecture is designed to meet the needs of organizations with wired LAN connectivity

requirements that range from a small, remote-site LAN to a large, multi-building location. The purpose of a

campus network is to support arbitrary device connectivity for workers and users in the office and business

spaces or meeting places of a building, such as for laptops, telephones, printers, and video conferencing

systems. This is in contrast to the highly controlled connectivity for servers in a data center or machine and

device connectivity in an industrial network or a WAN.

Many organizations have campus LAN requirements that include both wired and wireless access. The Campus

Wired LAN Technology Design Guide offers guidance designed, deployed, and tested in conjunction with

wireless guidance covered in the Campus Wireless LAN Technology Design Guide. Separation of the guides

allows more concise coverage of each design. Depending on the needs of the organization this provides

flexibility to use a single guide or multiple guides together as a set.

Technology Use Cases

This guide addresses the requirements of organizations when designing Local Area Networks (LANs) for their

data communications needs. The guidance offered is useful for greenfield designs, for optimizing existing

networks, and as a reference design offering operational consistency for an organization as its LAN grows. The

scope of coverage applies to small, remote-site LANs with a single router up to large multi-building campuses

with a routed core supporting connectivity to multiple-routed distribution modules.

This guide addresses four primary wired LAN requirements shared by organizations, including the need to:

• Offer reliable access to organization resources

• Minimize time required to absorb technology investments

• Provide a productive and consistent user experience

• Reduce operation costs

Use Case: Connecting Wired Devices to an Organization’s Network

Organizations of all sizes have a need to connect data devices used by their employees such as desktop

computers, laptops, and IP phones enabling communications with resources such as printers, business

applications systems, voice and video endpoints, and conference bridges, along with Internet accesses,

for interaction with partners and customers. Ethernet is the ubiquitous wired technology to make these

communication connections. Using this guide, a LAN design of a few Ethernet interconnected devices can scale

up to many thousands of devices in a multi-building campus over time.
