What is CumulusWhat is Cumulus Linux?

Linux-based Operating System for Ethernet Switches

What does it do?

Makes a switch behave like a Linux server with many ports

What are the customer benefits of Cumulus Linux?

Server like Linux interface (Bash shell) as the CLI

Server provisioning/management tools work on switch

Same NOS runs on switches from multiple vendors

Advanced IPv4/v6 Layer 3 feature set

Integrated with most Overlay solutions

Who is it for?

Linux admins who run the network

Cloud deployments

Linux across the Datacenter: Server, Storage, & Network

Network Automation


Why & What benefits of Automation ?

§ Automation benefis all network operators§ Smaller shops have a multitasking network operator§ Build predictable networks

What Benefits?

Why?§ Eliminate random errors§ Build predictable infrastructure§ Build scalable infrastructure


Choices for Automation

§ Netconf/Restconf§ Yang/Openconfig

Network Automation Tools

Server Automation Tools§ Ansible§ Chef§ CF Engine§ Puppet§ SlatStack

Culumus is Linux. So Any Tool Works out of the box


Automation is Key for Scalable Networks

§Manage the switch like a server with NetDevOps§ Do more with limiting resources§ Mitigating errors§ Helping operators manage more switches.

§Leverage existing automation tools and knowledge

§Adopting web-scale methodology§ Web-scale principles - learning from the hyperscale companies, they got it right!!!!§ Consistent experience between the network and compute, CLI can be used if preferred§ Delivering applications with higher SLAs and vastly reduced deployment times


Automation Use Cases

Rapid Provisioning Hot Swapping the Whole Switch

Configuration Management Reactive Network Changes Automatic Threat Response
