Cisco Confidential Challenges • Eight campuses including Texas Medical Center (13 buildings), seven comunity hospitals and 150 off-site locations comprised of emgerency, imaging, and primary care offices • A small staff: ten full-time employees, but only four people dedicated to wireless. • What’s the problem: With up to 50,000 clients on the network each day, wireless roaming and authentication issues arise but users may not necessarily report those issues. Wireless connectivity plays a critical role in patient care and satisifaction. Solutions & Outcomes Cisco’s DNA Center helps Houston Methodist Hospital achieve: • Better access to data: with a mostly wireless network, is able to easily detect devices throughout the network and solve any issues with the help of analytics. • Spolier Alerts: DNA Center helps the team to target small issues before they become big problems. Customer Case Study Houston Methodist Hospital Interview with Manuel Ortiz III Senior Wireless Engineer, HMH I like that DNA Center helps me find problems proactively, before users contact me. “ “

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 Stanford University 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! “ “

Cisco Confidential Challenges • The same experience at every park: unlike other sports, MLB is attempting to standardize the wireless network at all of their parks. This way fans of any team will have the same customer experience, no matter what park they call home. Solutions & Outcomes • Cisco Consistency: 18 out of 30 MLB parks are equipped with Cisco products allowing for the standardization and consistencey that Major League Baseball desires. • DNA Center starts in KC: Kauffman Stadium in Kansas City, MO is the first ballpark that is equipped with Cisco DNA Center. The plan is for all 30 stadiums to follow suit. • Already a hit: Once DNA Center was installed, an issue about performance degredation was spotted. Using DNA Center, the IT Manager was able to drill into the source and found that a switch interface—specifically an old, extended cable—was to blame. The cable was replaced and the Wi-Fi ran better than ever. Customer Case Study Major League Baseball Interview with Matt Swartz Advanced Services Principle Engineer Cisco Without Cisco DNA, solving this issue] was like looking for a needle in a haystack! “ “

Editor's Notes
- GOOD AFTERNOON & WELCOME. I am excited to be here today to INTRODUCE Cisco DNA Assurance which is the Next Chapter of The Network. Intuitive. Let us start by looking at a Day in the Life of a Network Admin {CLICK}
- As per the definition on the Internet, Context is …. In the Context of Networking, Context is {Click}
- Providing Visibility into Relationships between Users, Devices, Applications & Network with Granular Data & Time (Real-Time & Historical). -- with the ability to go back in time, and predict the future with predictive analytics. {CLICK} It can tell us the who, what, where, when, how … The QUALITY OF THE NETWORK IS KEY TO a great User/Client & IT Experience.. {CLICK} Cisco is taking context to entirely new level by showing all the interconnections between users, devices, things, applications and more -- with the ability to go back in time, and predict the future with predictive analytics. Before we get ahead of ourselves, I feel it is worth taking a minute to understand context and why it’s so important. Context is critical for IT and business. In a world where all things digital connect to the network, the network knows A LOT. What is Context? Visibility w/ Relationships Granularity Time It can tell us the who, what, where, when, how … Cisco is taking context to entirely new level by showing all the interconnections between users, devices, things, applications and more -- with the ability to go back in time, and predict the future with predictive analytics.
- IT Challenge – Find the needle in the haystack Over 100 places where things can go wrong between the user and application It spending 4X time collecting data than resolving Before, IT takes hours With DNA Assurance get to the root cause in minutes How? Breath and Depth: DNA Center provides E2E Assurance – users, clients, applications and network Portfolio offer broadest view of the network – routing, switching, wireless, security … plus client and app analytics ... continue to see how Cisco brings more and more into a single view (e.g, ISE, AppD, Service Now, etc.) Granularity – everything as a sensor … Aironet 4800 additional radio, WiFi Analytics for IOS devices (client experience) 16 sources of data and growing, most other vendors only have a few ... continue to drive to broader granulatriy Real-time Event driven telemetry … Infrastructure that pulls data when IT requires More efficient network data capture through telemetry in real-time (instead of SNMP traps)
- IT Challenge – Problem Replication WiFi is the most difficult issue to resolve – unlike the wired with relative predictability, the air results more changing variables Issues come and go with more rogue devices coming online Before: WiFi Issues come and go, and if IT cannot replicate, they cannot resolve Now IT can time travel and see how the user experience was impacted – with a 360 view and go predict issue and proactively validate the experience How? Cisco gives full contextual view for up to 14 days Years of Cisco learning on trends help determine issues about to impact users, so IT can get in front of them New Aironet Active Sensor offer a better way to proactively validate air quality and user experience, especially for VIP and events
- IT Challenge – Resolution Before, IT needed continuous training on resolving issues Now they can leverage 30 years of industry experience and best practice to take action How? Guided remediation – seeing how many impacted and how to address issue – for wireless degradation to WAN bandwidth challenges … many time proactively getting alerts before they impact users. Today, IT staff continues to turn over as a new generation of workers on board. We now offer a better way to provide knowledge transfer and help IT resolved issues faster with guided remediation. As the network now connects all things digital, it can support operational work streams to support asset management and IoT https://www.randgroup.com/insights/cost-of-business-downtime/
- This is the power of DNA Center Assurance. It take al the rich network data and puts context around it. Now, It can see a full picture on users, clients, applications and the network. This includes: Onboarding and connectivity – think about all the times you needed to make multiple attempts to get on the network; once you were on, you didn’t notificy IT … but it would be useful for them know know if an AP is being oversubscribed Visibility and performance – users assume it is the network impacting application, now you can validate it that is in fact the case, and resolve the issue ... perhpas the DNS server is limiting access. Configuration compliance ... this is where intent and context work hand in hand. You set your policy, or intent, now you need to make sure it is enforced. This is critical when needing to maintain industry compliance. Network Health ...which provides the BIG picture and helps IT know where to focus. But even better is that through machine learning, we can also predict issues, so that IT is not chasing it’s tail, but rather addressing degration to minimize downtime and improve productivity
- Extended quote from Manuel: Houston Methodist Hospital, Manuel Ortiz III, Senior Wireless Engineer “DNA Center helps me find problems proactively, before users contact me. With a mostly wireless network, I’m able to find devices throughout the network and quickly solve any problems with the help of analytics. ”
