I had a colleague the other week ask about changing a few hundred NSX Edges Syslog address. There was some configuration drift in the environment where the edges fell into a few different categories. The Edges either didn’t have configuration,…
In our line of work we are often deployment clean NSX environments in the lab. One of our labs allows us to deploy a multi-cluster vSphere environment and configure it with storage, clusters, vCenter elements, and DVS with PowerCLI very…
There are a lot of times where people have asked it would be great to have an ability to clone an edge. Take all the configuration and duplicate it easily. Well now you can. The Copy-NsxEdge function takes an already…
At VMworld US and Europe this year, Nick Bradford and I presented on PowerNSX. PowerNSX provides a PowerShell module featuring a substantial number of cmdlets that cover the NSX API. Working in concert with PowerCLI it becomes possible to interact…
This blog looks to highlight a solution to ingress routing for multi-DC networks and their applications that have location independence using overlay protocols such as VXLAN. It takes advantage of events occurring within the infrastructure and manipulates the network accordingly. This…
Response: Linux on Network Switches make sense for your career Greg Ferro posted an article over at EtherealMind which highlights the shift and desire in the industry to move to Linux based Network Operating Systems (NOS). What Greg intones with…
In my previous post I used an API call from a REST client that allowed me to purge all the rules within the Distributed Firewall function of NSX. I have also made this into a python script. The snake script…
Firewall cleanup This post will show how to purge all the Distributed Firewall rules created by NSX. In my studies for the VCIX-NV certification I managed to build some interesting rule sets and was applying them to all sorts of…
Lay of the land Just a quick one today. It is possible to set a syslog server for each NSX controller. This will allow for reporting of events to a syslog server. In my case, I have LogInsight (LI)clustered behind…
A customer was wanted to validate the impact of numerous firewall rules within NSX. The thought was how much impact on cores of the CPU host and distributed firewall throughput when NSX had 100, 500, and 1000 rule sets loaded.…
As has been purported many times it is possible to create objects via a RESTful API. Lets first look at the logical network segments in my environment. Whilst I show the GUI creation here this post highlights the the GUI…
APIs and programmatically delivering network function is the impetus to change from older networking thought processes into the modern and future architectures. For some time now many networking vendors have been providing API function. NETCONF configuration via Python allows Juniper…
I have been working with the RESTful API within NSX for vSphere a bit lately. I have been standing a few environments up with a python script that makes sequential API requests to the NSX manager. This has been pretty…
