These are the slides....but you need to watch the replay so you can benefit from the demo! This was easily one of our most popular sessions with a HUGE number of attendees smashing previous records. REPLAY: cs.co/9001BMjah Q&A Added on Nov 3, 2015: http://www.slideshare.net/robboyd/qa-from-cisco-modeling-labs-workshop DESCRIPTION: Building physical networks can be a slow, painful, and repetitive task. We often spend more time building the physical aspects of rack, cabling, and configuring and end up rushing the actual work. In Simulating Networks using Cisco Modeling Labs, we will look at how you can simplify the building of labs using network virtualization. What is the architecture behind the system, the type of routers and switches you can use, the performance and capacity considerations, a demonstration of the product, and finally the gotchas for planning and building a virtual network.

2. Agenda
• Problems and Challenges
• Solution
• Benefits of Cisco Modeling Labs
• Architecture and Platforms
• Steps for Creating a Simulation
• What’s New in CML 1.1
• Reference Platforms
• Cisco Modeling Labs Requirements
• Installing Cisco Modeling Labs Server
• Cisco Modeling Labs Vs VIRL PE

3. The Problem
• Designing, building, testing and launching physical networks can be an expensive, complex and
time-consuming endeavor, and the Internet of Things (IoT), big data, the cloud, and mobile
computing are putting a premium on the need to speed up the process
• Currently it can take days to build out a network before it can be tested, validated and deployed

4. The Challenge
• Testing new OS versions and features
• Staging new deployments
• Troubleshooting problems
• Developing new offerings
• Limited access to lab; both physically and
across network
• Purchasing and maintaining non-production
hardware
• Providing hands-on experience across teams
How do you test networking solutions at
scale, with time and budgets constraints and
without harming live networks?

5. A scalable software platform that enables teams to
design, build, test, and deploy real-world
simulations in a virtual environment
• Create models and what-if scenarios of real-world/future
networks
• Visualize network topologies from protocol perspectives
• Modeling of traffic patterns and network errors
• Scales to 100s of virtual network and server devices*
• Interact with other vendors; externally connected
and within simulation
• Leverage “real” network operating systems – routers,
switches, Linux
• Provide Confidence that the network is Production
Ready
The Solution
Cisco Modeling Labs

6. Cisco Modeling Labs
Corporate Edition is the
ideal network simulation
solution. It provides a virtual
environment to design,
build, simulate, and visualize
real-world networks and
operational scenarios.
With its simple point-and-
click interface, network
engineers can design or
import a network topology
and turn it into a virtual
network in minutes.
• Point-and-click design
• Automated configuration
generation and protocol
visualization
• Virtual Cisco IOS Software
for router and switch
simulation
• Support for other IOS
devices and 3rd party
images
• Multi-client support
• Connectivity between
simulated and physical labs
• Lower capital and operating
expenditures
• Provide on-demand access
to resources
• Scale resources on
demand
• Decrease deployment time
of new services
• Increase uptime with what-
if scenarios
• Reduce lab footprint
• Save energy, go green

25. CML v1.1 – Client Requirements
Requirement Description
Memory (RAM) 500 MB
Disk Space 200 MB
Operating System

27. • The key factor for determining memory is to determine the number of virtual
devices (nodes) that you want to simulate. This should be based on a
cumulative number of:
• Concurrently active simulations and the sizing of the topologies
• Types of nodes that users can activate, for example, Cisco IOS, IOSvL2, IOS XRv, CSR
1000v…etc.
