Challenges
• A large campus: Over 8,000 acres and 45,000
clients daily at peak times. More devices during one
of the University’s many on-campus events.
• Lots of people, using lots of apps: With more than 20
different types of wireless client hardware in use on
campus, all need to work on the network. Issues can
arise when supporting students’ personal streaming
devices and smart home applications.
Solutions & Outcomes
Cisco’s DNA Center helps Stanford University to
achieve:
• Information, where you need it: “DNA Center has the
opportunity to be the Holy Grail of wireless
management,” Norris said. “The products is focused
on providing the end-user with all of the information
needed to design, run and troubleshoot a large
network. The client data is presented in a clear and
thoughtful way, providing all of the data you need
within two or three clicks.”
Customer Study

Residential Dept.
Drew Norris, Sr. Network Engineer, Stanford University
Cisco DNA Center is a great idea
packed with a lots of potential.
Cisco is moving in the right
direction!
