After years of setbacks, Infinera is back.
My amazing California journey as a French undergrad software engineer.
Most days, the first thing I do in the morning is wake up and check my email. That’s normal, but on March 2014, I received a special email that would change my life forever. This email was from the Cumulus Networks VP of Engineering, Shrijeet Mukherjee, offering me an internship on the Cumulus Networks engineering team. I was so thrilled that I literally jumped out of bed and started the victory dance (which by the way is much stronger than a cup of coffee).
I could have ended up interning at a less “cool” random French consulting company, but I wasn’t really passionate about this option anymore now that I had the opportunity to join the hottest startup in the networking industry in Mountain View, California.
I’m so excited to share my experience!
My time at Cumulus Networks, May through September 2014, was the final internship of my bachelor program at EPITECH in Rennes, France, where I’ve been pursuing a 5-year Bachelor/Masters degree in Software Engineering. I had several internship offers in various parts of the world (Germany, Philippines, Estonia and of course, France) but I turned down all of them to Continue reading
Following up on my earlier post on Cumulus Linux networking concepts, I wanted to build on that information with a guide on configuring VLAN trunking. This would be useful in a number of different scenarios: supporting multiple (VLAN-backed) port groups on vSphere hosts, or connecting an Open vSwitch (OVS) bridge on a KVM or Xen hypervisor to multiple VLANs. You might also need to use a VLAN trunking configuration to connect a Cumulus Linux-powered switch to another switch.
For this configuration, I’m going to use the new VLAN-aware bridging functionality introduced in Cumulus Linux 2.5. There are two pieces involved in making this work:
Let’s look at each of these pieces individually.
In order to provide layer 2 (switched) connectivity between front-panel ports on a Cumulus Linux-powered switch, the ports have to be part of a bridge. In this case, we’ll create a VLAN-aware bridge, which simplifies the configuration (in my opinion). It’s a bit less “true” to the Linux way of doing things, but simpler.
Owing to its Debian roots, you’ll configure the bridge by either adding a stanza to /etc/network/interfaces

This is it. Your last shot to register for the Cisco VIRL DemoFriday. Can your organization keep up with the increasing demand to provide new network services while still making significant changes to test and deploy networks consistently? If not, then the Cisco DemoFriday may be just for you. In this DemoFriday, Cisco will take us through VIRL (Virtual Internet Read more >
After I wrote a comment on a LinkedIn discussion in the Carrier Ethernet group (more details here), Vishal Sharma wrote an interesting response, going into more details of distinction between centralized control and centralized control plane.
