What you'll learn

Confidently discuss Linux based networking
Configure Cumulus Linux switches

* Requirements

* CCNA or equivalent knowledge is recommended

Description

The course includes hands on demonstrations using both Cumulus VX and physical switches. The best part is you can practice using GNS3 and Cumulus VX locally on your laptop!

Cumulus Linux combines the power of Open Networking with a network operating system that runs on top of industry standard networking hardware from vendors such as Dell, HP, Quanta and others. Founded by veteran networking engineers from Cisco and VMware, Cumulus Networks makes the first Linux operating system for networking hardware and fills a critical gap in realizing the true promise of the software-defined data center. Just as Linux completely transformed the economics and innovation on the server side of the data center, Cumulus Linux is doing the same for the network. It is radically reducing the costs and complexities of operating modern data center networks for service providers and businesses of all sizes.

By providing a software-only solution, Cumulus Linux is enabling disaggregation of data center switches akin to the x86 server hardware/software disaggregation. Data-center networking is rapidly standardizing on merchant silicon and with Cumulus Linux, networking is adopting the principals of Linux and disaggregation of the compute world.
