What are the options?• Ignore it – this is a fad and it will never affect me
• Wait – I’m not interested in spending time on things that may not exist in a year
• Inform – become familiar with the concepts and technologies
• Prepare – start learning some of the core skillsets with the belief they’re valuable
• Proof of Concept – some of the benefits directly affect my business and ‘we need this’
• Start in Pre-production – it’s important enough that we’ll have developers start with it
• Production – F*** it, let’s do it live!
The business
“When do we want it?…NOW!”
The Application and Business Users Have Other Choices
API’s Are Everywhere

We’re already programming• CLI is a programming language
• However, very inflexible
#show run | i access-list
vs
#cat running-config.txt | grep access-list
Router#config t(config)#interface gig0/0(config-if)#access-group 101 in
vs
import clicli.config.acl(“gig0/0”,101,”in”)
In the Age of the Smart Machine: The Future of Work and Power

The OS and Sys Admins Did It First - DevOps
A change from manually configuring every server, operating system, and virtual machine to operating a nimble set of infrastructure at scale
1 Server Admin : 100-200 Servers to1 Server Admin : 5,000 – 10,000 Servers
CLI + Bash scripts + Reactive configuration toOrchestrated configuration and integration with development
Network Operations
That Sounds Like A Lot Stuff.
You don’t need fluency – “Dondey Estas Las Bano”
• There are core skills that will be useful even if the technology winds change direction
• Knowing the terminology and context will allow you to make better decisions for you and your team or business
• Having knowledge of someone else’s problems and process opens up opportunities to solve mutual pain
Core Skills for Network Programming• Linux / Shell
Most programmatic interfaces are enabled through Linux devices.
Guides and how-to’s will often be Linux only
Mac OSX users are more empowered with a linux-like BSD shell
Can have a steep learning curve – very distributed
• PythonMost popular scripting language
Forgiving and easy to use
Large ecosystem of support
• Git / GitHubModern software configuration management tool – keeping track of code and sharing it
• Terminology AwarenessTLA’s (three letter acronyms) and open source tools abound – which ones matter?
Goal of NPUG
Let’s get through this together• There are so many technologies and diverse skillsets that a group is the best fit
• Create a learning environment
• Hearing from people using it will help cut through marketing hypeStories of migration – before/after
Show and Tell – technology how-to’s or small labs
Collaboration on projects – coding together and matching needs with capabilites
Technology Updates – what should we be aware of
• Open Source contribution is scaryAfraid to be mocked or that your contribution is dangerous to the code
Let’s create a playground so that we can start somewhere
• Minimize Vendor Marketecture and SalesStay away from sales and marketing pitches
More real facts, actionable technology, gotcha’s, and networking
Format of the Group - Tentatively
Once a month in person meetings, tentatively at the Cisco office
3-6 week weekly virtual meetings that are user-driven on certain topics like linux, python, etc.
Time? Interest? Speakers?
Occasional Labs and HackathonsSpend 4+ hours playing with Technology hands-on, mixing skill levels
Chat on the google group alias For help, question, thoughts, comments, announcements, flame wars

Technologies we can get our hands on now• Arduino + Raspberry Pi projects
• Python Shells
• VIRLVirtual routing lab – running on OpenStack. GNS3 on steroids
Join the mailing list – an email will be sent out about access : [email protected]
• OnePK All in One VMhttps://developer.cisco.com/site/networking/one/onepk/sdk-and-docs/all-in-one-vm/index.gsp
• Python Shell on Nexus devices
• API’s and Puppet on Nexus 3000 + 9000
• EEM – Routers and Switches
• Devnet Sandboxes – still in development
• DevStack and Openstack VM builds

Some Ideas We Can kickstart (advanced)• Automated packet capture
Get a packet capture in the network on demand
Methods:
CLI scripting with capture export feature
OnePK extraction via C SDK
Extend on Monitor Manager
• Other ideas or requests?
VIRL Demo
