Resetting expired admin password on NSX-T

Resetting expired admin password on NSX-T

Comments 6 comments

So apparently it has been 90 days since the deployment of NSX-T and therefor, time for the admin password to expire ;): Unfortunately, this doesn’t give you the opportunity to login and then change the password (a feature I would really appreciate), but a reset is necessary. In the online documentation (https://docs.vmware.com/en/VMware-NSX-T-Data-Center/2.4/administration/GUID-8816B842-2EC4-40A8-A618-F68DB29FABD2.html) the reset is done through a reboot into single user mode of one of the appliances and reset the password. However, in the online documentation one of the…

NSX-T: Missing locale data for the locale “XX”.

NSX-T: Missing locale data for the locale “XX”.

So, as you may know, I am from the Netherlands (or Holland, although technically I am not, but that is a different discussion ;)). So within my lab-environment I sometimes use Dutch as the language-setting, for instance within Firefox, the browser I use(d) to configure NSX-T. But this issue also occurs in Chrome. Within IE (although I only used that to test if it was affected by this ;)), the page doesn’t load at all. When I try to open…

Load Balancing with NSX-T – Part 1

Load Balancing with NSX-T – Part 1

Comments 4 comments

So after I looked at the installation, the fabric and routing and switching, it is time to take a look at the higher level networking functions within NSX-T, like Load Balancing. The functionality itself has not changed very much since NSX-T (compared to V), but the way that it is consumed is different.

As described in an earlier blog (Routing with NSX-T (part 1)), NSX-T uses multiple entities within it’s fabric. Two of which being tier-0 and tier-1 gateways and load balancing can only exist on a tier-1 gateway. So when you use Load Balancing within NSX-T you have to deploy both tier-0 and tier-1 components.

So after the theory, it is time to create some routed networks. In order to do this, I created a design on what I want to accomplish. Part of the design is already in place, but for this blog I have created the part which is visible in the red square: So we already have a tier-0 gateway, connected to a tier-1 gateway, which is connected to several segments. The existing tier-1 is also used as a load balancer for…

As someone who has worked with NSX-V for quite some time, routing within NSX-T is a little bit difficult to grasp. The terminology might be only slightly different, the concepts are completely different. Within NSX-V, you had E-W routing, through a DLR and N-S routing through one or more ESG’s, either in HA or in ECMP. That was all pretty straight forward. The addition of statefull service could only be performed by ESG’s and if so, the ESG’s would not…

So, as you might know, I work for a company called PQR (www.pqr.com). Within PQR it is important for us to be able to show our customers all the functionality that they might be interested in, before implementing it themselves. This started of with something called the PQR Experience Center (or PEC for short), which was mainly focussed on the workspace part of IT. In it, we are able to show customers how they can use workspace components within their…

Migrating from Standard Switch to NVDS with NSX-T 2.4

Migrating from Standard Switch to NVDS with NSX-T 2.4

Comments 6 comments

So, I have started developing my knowledge around NSX-T. No formal training, but I do have an environment, in which I can try out things. So I set up a basic NSX-T environment, consisting of one NSX Manager/Controller (starting with 2.4 this is a combined function, which can be clustered), and I created all the necessary stuff to make routing and switching available to virtual machines, by use of overlay networking. One other thing I wanted to try, is to…
