Cumulus Linux Network Command Line Utility

Here at Cumulus Networks, we believe that network engineers are the real heart of an organization. They’re the ones managing switches, running the data center, and generally keeping an organization moving efficiently and securely.

We also believe web-scale networking and the associated benefits should be accessible to everyone and the best way to make that happen is to leverage the power of disaggregation and native Linux. Although web-scale networking is very flexible, agile and offers many benefits, there can be a learning curve as Linux uses separate, independently developed applications which each have their own syntax to configure the switch.

So how do we bridge these two beliefs? Allow us to introduce Cumulus Linux Network Command Line Utility (NCLU). Scheduled for our early December 3.2 release, NCLU empowers and quickens the learning curve so all network engineers can benefit from web-scale networking while integrating with and still supporting the traditional Linux methods. In short, NCLU makes Cumulus Linux easily accessible to everyone.

What is Cumulus Linux Network Command Line Utility?

NCLU is a command line utility for Cumulus Linux that rides in the Linux user space as seen below. It provides consistent access to networking commands directly via bash, Continue reading

Can VMware NSX and Cisco ACI Interoperate over VXLAN?

I got a long list of VXLAN-related questions from one of my subscribers. It started with an easy one:

Does Cisco ACI use VXLAN inside the fabric or is something else used instead of VXLAN?

ACI uses VXLAN but not in a way that would be (AFAIK) interoperable with any non-Cisco product. While they do use some proprietary tagging bits, the real challenge is the control plane.
