Let s get back together for a glimpse into next version

5 Introduction to DNA Center and Intuitive Networking

6 The Cost of Doing * Business in the Digital World $60B Spent on Network Operations Labor and Tools Why are companies spending so much? 95% 70% 75% Network Changes Performed Manually Policy Violations Due to Human Error OpEx Spent on Network Changes & Troubleshooting *McKinsey study conducted for Cisco in 2016 LTRNMS Cisco and/or its affiliates.

16 Using DNA Center for Base Network Automation

17 Use Case #1: Standard Network Settings Update DHCP Server North America EMEAR DNS Server Use Case: Adding a new Syslog (Ex: Splunk) in the network SoX requirements to update password every 6 months Syslog Server South America Site2 AAA Server Benefits: AAA Server Site1 Africa Syslog Server Repeated manual error prone tasks automated Eng get additional time to focus on design and deployment Standard change automation removes the lead time to make changes LTRNMS Cisco and/or its affiliates.

19 Use Case #3: Wireless Deployment Made Simple o o o o o Automation Discover WLC Create Site(s) with Buildings and Floors Design Wireless Profiles Provision WLC and AP Connect wireless client LTRNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 19

20 Use Case #4: Managing Software Lifecycle Use Case: Ensure Consistency of Software for all network devices (by platform type) React to PSIRT and bugs fast Deploy software with confidence Benefits: Golden Image based workflows drive software consistency Pre/Post check ensures that software updates do not have adverse effects on the network Patching provides small updates to react quickly to security fixes LTRNMS Cisco and/or its affiliates.

21 Using DNA Center for Application Policy

22 Application Policy Applications can interact with DNA Center via Northbound APIs, informing the network of applicationspecific and dynamic QoS requirements Network Operators express high-level business-intent to DNA Center Application Policy DNA Center Policy Automation Analytics Southbound APIs translate business-intent to platformspecific configurations Wireless AP Trust Boundary PEP 4Q (WMM) Catalyst P7Q1T Nexus 7700 F3: 1P7Q1T ASR/ISRs MQC Wireless AP Trust Boundary PEP 4Q (WMM) Catalyst 3650 Trust Boundary PEP 2P6Q3T Catalyst P3Q4T 1P7Q4T 2P6Q4T WLC PEP Catalyst 2960-X Trust Boundary PEP 1P3Q3T LTRNMS Cisco and/or its affiliates.

23 Solicit Application Business-Relevance Relevant These applications directly supports business objectives Applications should be classified and marked according to RFC 4594-based rules Default These applications may/may not support business objectives E.g. HTTP/HTTPS Alternatively, administrator may not know the application (or how its being used in the org) Applications in this class should be marked DF and provisioned with a default best-effort service (RFC 2474) Irrelevant These applications are known and do not directly support any business objectives; this class includes all personal/consumer applications Applications in this class should be marked CS1 and provisioned with a less-than-best-effort service, per (RFC 3662) LTRNMS Cisco and/or its affiliates.
