Campus lan and Wireless lan solution Design Guide

Cisco Digital Network Architecture (Cisco DNA) 
Cisco Digital Network Architecture (Cisco DNA) provides a roadmap to digitization and a path to realize 
immediate benefits of network automation, assurance, and security. The campus local area network (LAN) is the 
network that supports devices people use within a location to connect to information. The use of the word 
campus does not imply any specific geographic size or organizational boundary—the campus LAN can range in 
size from a single switch at a small remote site up to a large multi-building infrastructure, supporting 
classrooms, carpeted office space, and similar places where people use their devices for their daily activities. 
The campus design incorporates both wired LAN and wireless LAN connectivity for a complete network access 
solution. This guide explains: 
● 
The design of the campus wired LAN foundation. 
● 
How the WLAN extends secure network access or is exclusive network access for your mobile workforce. 
● 
How the WLAN can provide guest access for contractors and visitors to your facilities.

Design: Campus LAN and Wireless LAN 
Designing a LAN for the campus use case is not a one-design-fits-all proposition. The scale of campus LAN 
can be as simple as a single switch and wireless AP at a small remote site or a large, distributed, multi-building 
complex with high-density wired port and wireless requirements. The deployment may require very high 
availability for the services offered by the network, with a low tolerance for risk, or there may be tolerance for 
fix-on-failure approach with extended service outages for a limited number of users considered acceptable. 
Platform choices for these deployments are often driven by needs for network capacity, the device and network 
capabilities offered, and the need to meet any compliance requirements that are important to the organization.
