This 6 days OR 6 weekends, 48 hours, instructor led Cumulus Linux course is a hands-on training course targeted at network and system administrators. This course explores architecture, installation, configuration, operation and management of Cumulus Linux running on bare metal switches.
Course Introduction
Cumulus Networks unleashes the power of open networking and accelerates its adoption with Cumulus Linux, the operating system for open networking. Modern data centers need great physical networking for layer 2, layer 3 and overlay architectures, with the added benefits of improved economics and a robust ecosystem. By enabling switch disaggregation and use of well-known Linux tools, open networking liberates those networks and empowers the people who run them. With Cumulus Linux and bare metal switching from our extensive hardware compatibility list, your data center network is open, responsive and affordable. This course is a perfect mixture of theoretical and hands-on training for networking professionals which teaches how to install, deploy, configure, operate and troubleshoot Cumulus Linux.
