The VMware NSX network virtualization platform allows us to build sophisticated networking and security constructs in software. NSX has a rich RESTful API which allows one to build highly flexible and automated environments. In this blog, we’re going to focus on operations and automation; we’ll demonstrate one example of automation around security policies/rules that can be done with NSX.
VMware NSX allows for micro-segmentation with a distributed firewall service (DFW). The DFW is a kernel-level module and allows for enhanced segmentation and security across a virtualized environment. One of the common questions we get asked is, “how do I decide what rules to build?” NSX allows for multiple options to create rules such as the use of NSX flow-monitoring or analyzing traffic patterns via logging to create the rules.
We’ll demonstrate how the VMware NSX DFW can be monitored with the popular Splunk platform. Further, we’ll demonstrate, along with using Splunk for monitoring traffic passing through the DFW, how the NSX REST API can be leveraged to automate workflows and creation of DFW rules. Continue reading
The Cisco CCIE Lab Builder allows you to run your R&S topologies in the actual CCIE Routing & Switching virtual environment.

If I input MPLS traffic engineering on any search engines, I will find about 100 articles on the internet providing the same explanations about MPLS traffic engineering. But unfortunately, nobody ask these questions: do I really need it? What are the reasons behind the implementation of MPLS Traffic Engineering? Would it worth the time and energy […]

A while ago I watched a Networking Field Day Extra video in which Chris Young and Michael Zayats talked about HP’s open source initiative – they decided to build yet another open networking operating system.
Obviously I wanted to know more, reached out to Chris, and we quickly managed to set up an online chat resulting in Episode 48 of Software Gone Wild podcast.

Unfortunately I had a bit of a brain fade, and configured sFlow to use port 2055, not port 6343. So it looked like this:
vagrant@ubuntu:~$ tcpdump -r sflow.cap reading from file sflow.cap, link-type EN10MB (Ethernet) 13:48:37.812602 IP 10.254.4.125.44695 > 10.254.4.170.2055: UDP, length 148 13:48:57.813663 IP 10.254.4.125.44695 > 10.254.4.170.2055: UDP, length 148 13:48:59.061629 IP 10.254.4.125.44695 > 10.254.4.170.2055: UDP, length 232 13:49:17.806908 IP 10.254.4.125.44695 > 10.254.4.170.2055: UDP, length 148 13:49:37.804433 IP 10.254.4.125.44695 > 10.254.4.170.2055: UDP, length 148 13:49:57.806000 IP 10.254.4.125.44695 > 10.254.4.170.2055: UDP, length 148 13:50:17.808959 IP 10.254.4.125.44695 > 10.254.4.170.2055: UDP, Continue reading
