Introducing New NSX Upgrade Capabilities for NSX-T 3.2

We’re introducing new capabilities to help our customers prepare for upgrading to the latest releases — now available with NSX-T Data Center 3.2.0.1.

To ensure that existing NSX deployments can be successfully upgraded to NSX-T Data Center 3.2.x, we have provided an NSX Upgrade Evaluation Tool that operates non-intrusively as a separate downloadable tool to check the health and readiness of your NSX Managers prior to upgrade. Using NSX Upgrade Evaluation Tool can help avoid potential upgrade failures and save time by avoiding a rollback from a failed upgrade.

Customers upgrading to NSX-T 3.2.x are strongly encouraged to review the Upgrade Checklist and run the NSX Upgrade Evaluation Tool before starting the upgrade process.

In what follows, we’ll go over the details of the NSX Upgrade Evaluation Tool:

  • How the tool works
  • When to use the tool
  • What the tool can and cannot do
  • How to use the tool

How the NSX Upgrade Evaluation Tool Works

The main component of the NSX Upgrade Evaluation Tool is the database where a copy of NSX objects will be stored. The tool starts by making a secure copy of the database from an existing NSX Manager Continue reading

Burkina Faso experiencing second major Internet disruption this year

Burkina Faso experiencing second major Internet disruption this year

The early hours of Sunday, January 23, 2022, started in Burkina Faso with an Internet outage or shutdown. Heavy gunfire in an army mutiny could be related to the outage according to the New York Times (“mobile Internet services were shut down”). As of today, there are three countries affected by major Internet disruptions — Tonga and Yemen are the others.

Cloudflare Radar shows that Internet traffic dropped significantly in the West African country after ~09:15 UTC (the same in local time) and remains low more than 24 hours later. Burkina Faso also had a mobile Internet shutdown on January 10, 2022, and another we reported in late November 2021.

The main ISPs from Burkina Faso were affected. The two leading Internet Service Providers Orange and FasoNet lost Internet traffic after 09:15 UTC, but also Telecel Faso, as the next chart shows. This morning, at around 10:00 UTC there was some traffic from FasoNet but less than half of what we saw at the same time in preceding days.

It’s not only mobile traffic that is affected. Desktop traffic is also impacted. In Burkina Faso, our data shows that mobile devices normally represent 70% of Internet traffic.

5G deployment near US airports slowed for now

5G deployments are proceeding around the country, albeit more slowly, after a partial agreement between the FCC and the FAA about the potential danger of 5G transmissions generated too strong and too close to airports on bandwidths adjacent to the spectrum used by airplane altimeters.President Biden announced that Verizon and AT&T had agreed to slow deployments of 5G around major airports after consultation with the Department of Transportation, in order to assuage concerns over air travel safety.What is 5G? At issue is potential interference between newly opened 5G spectrum in the 3.7GHz range and radioaltimeter equipment on older aircraft. While there’s some separation between the 3.7GHz 5G signals, which top out at 3.98GHz, and the bottom of the 4.2GHz range used by the avionics equipment, the FAA and the airline industry remain concerned over potential interference that, theoretically, could prevent affected aircraft from landing safely in low-visibility conditions.To read this article in full, please click here

6G exploratory group to be led by wireless heavyweights

The FCC has named 44 people to a technological advisory council tasked with exploring the possibilities of 6G wireless connectivity, a large proportion of the council’s members being drawn from the ranks of the country’s biggest networking-technology corporations.The chair of the committee will be a former Qualcomm executive, Dean Brenner. Intel, Cisco, Comcast, Microsoft, Nokia, Ericsson, and all of the major mobile operators are also represented on the commission’s Technological Advisory Council (TAC). Also representatived are large trade associations and academia.6G’s vast promises FCC chairwoman Jessica Rosenworcel said that leadership in the 6G realm has to be a priority for the US.To read this article in full, please click here

Automation 10. Installing NAPALM Community Driver for Nokia SRO OS and comparing NAPALM and OpenConfig/YANG.

Hello my friend,

In the previous blogpost we have compared the usage of NAPALM and OpenConfig YANG modules with NETCONF transport for Cisco IOS XR and Arista EOS. Those two operation systems are so called core operating systems for NAPALM and are included in its standard distribution. Besides them, other three (there are five core network operating systems in NAPALM) are Cisco IOS, Cisco Nexus, and Juniper Junos. You though can use NAPALM with other operating systems, if there are community drivers available. In today’s blogpost we cover installation and usage of NAPALM Community Driver for Nokia SR OS and its comparison against OpenConfig/YANG with NETCONF.

How Is It Important to Know Python?

Recently we were engaged with one of our customers to help with OpenStack deployment. The first step for us was to build the lab, which could replicate the desired setup. The installation of OpenStack manually (there are means to automate that as Continue reading

Simplifying Multi-Cloud Networking: Stateless, Competitors See Opportunity In NaaS

This article was originally posted on Packet Pushers Ignition on May 12, 2021. To business executives and the IT subordinates seeking to appease them, being a cloud-first company is no longer enough. Now they feel compelled to be multi-cloud, on the premise that if one is good, two or more are better. Multi-cloud adherents believe […]

When you’re out and about, and especially when you’re traveling, you might find yourself feeling quite a bit of anxiety when logging into public Wi-Fi.


There are a lot of resources out there on Twitter, Reddit, and YouTube about this epic vulnerability. I wanted to create this post to summarize the main things I learned, ways to test it as pentester, and the mitigation controls that help prevent the exploitation of this vulnerability.


A Romanian vulnerability researcher has discovered more than 70 flaws in combinations of cloud applications and content delivery networks (CDNs) that could be used to poison the CDN caches and result in denial-of-service (DoS) attacks on the applications.


As we look ahead into 2022, the datacenter compute landscape is considerably richer than it was a decade ago.


In a perfectly regulated industry, both the industry and the public should be miffed at regulators for not fully supporting their issues.


One could argue that the last few years have highlighted some of the most pressing semiconductor industry issues but there are challenges on the horizon well beyond current supply chain and silicon manufacturing bottlenecks.


In light of recent incidents that impacted both information technology (IT) and operational technology Continue reading

The Demise of G-Suite

In case you missed it this week, Google is killing off the free edition of Google Apps/G-Suite/Workspace. The short version is that you need to convert to a paid plan by May 1, 2022. If you don’t you’re going to lose everything in July. The initial offering of the free tier was back in 2006 and the free plan hasn’t been available since 2012. I suppose a decade is a long time to enjoy custom email but I’m still a bit miffed at the decision.

Value Added, Value Lost

It’s pretty easy to see that the free version of Workspace was designed to encourage people to use it and then upgrade to a paid account to gain more features. As time wore on Google realized that people were taking advantage of having a full suite of 50 accounts and never moving, which is why 2012 was the original cutoff date. Now there has been some other change that has forced their hand into dropping the plan entirely.

I won’t speculate about what’s happening because I’m sure it’s complex and tied to ad revenue and privacy restrictions that people are implementing that is reducing the value of the data Google has Continue reading
