VMware NSX-T and NSX networking guides covering design, deployment, overlays, routing, security, automation, upgrades, and troubleshooting.
A single logical switch is mapped to a unique Geneve segment that is distributed across the ESXi hosts in a transport zone. The logical switch supports line-rate switching in the ESXi host without the constraints of VLAN sprawl or spanning tree issues. A segment is a representation of layer-2 connectivity across transport nodes (ESXi Hosts), … Explore: NSX-T – Deploy Segment (Logical Switch)
A Tier-1 Gateway can span multiple ESXi and KVM hosts. A Distributed Router can provide local routing between different segments on a host. A DR also provides distributed east-west routing functionality across hosts. Things to know about a T1: T1 uplinks to a T0 router T1 has down links to segments Owned and config by … Explore: NSX-T – Deploying Tier-1 (T1) Router
When it comes to a multi-tier router architecture you will be connecting Tier-1 router(s) to an existing Tier-0 router. East-West routing is performed by the DR (distributed Router) in the Tier-1 router. The Tier-0 provides services and external connectivity. Some things to be aware of: When the service and distributed routers are created, they are … Explore: NSX-T – Attach a Tier-1 Gateway to Tier-0…
One of the things I like about NSX-T is the ability to deploy Tier-1 and Tier-0 routers. The T0 is the gateway that bridges the virtual world to the physical world. Below you will find a screenshot of the logical architecture followed by a step by step process to deploy a T0 router in your … Explore: NSX-T – Deploying Tier-0 (T0) Router
As I continue my blogging series on deploying NSX-T 2.4 in your environment, my next topic will be Domains. This will be a quick blog as there is not a lot about setting up Domains. Domains will pop up a lot when configuring NSX-T. They are great for logically grouping a collection of workloads and … Explore: Deploying a Domain in NSX-T
Many asked so here it is. A how to guide on leveraging Tags and Security Groups to apply Firewall Policies/Rules to groups of VMs. My main goal for this article is to simplify a complicated 2.4 Admin Guide, which does not spell out how to do this in step by step options. The Admin Guide … Explore: NSX-T Applying Micro-Segmentation with Tags
There may be instances when you want to leverage NSX-T for NAT services and not an external NAT services. Thanks to the simplified management of NSX-T deploying these services is easy. Terms:Source NAT (SNAT): translates a source IP address of outbound packets so that packets appears as originating from a different network Destination NAT (DNAT): … Explore: Deploying NAT Services on NSX-T
Over the past couple years I hear the term Micro-Segmentation over and over and over and over again as the benefit of NSX & software defined networking. I thought I would take a moment to write about four benefits of NSX-T I’m witnessing in my environments that bring value add on top of Micro-Segmentation. 1. … Explore: Four Benefits of NSX-T Not Named Micro-Segmentation
I wanted to take a moment and provide a link to the new feature release of NSX-T 2.4. This has been a major release with a re-architecture of the NSX-T components. Some feature highlightsCombining the NSX Manager and Controller nodes into a single applianceInfrastructure as CodeExpanding Security FeaturesHigher Levels of Scale, Resiliency, Performance https://blogs.vmware.com/networkvirtualization/2019/02/introducing-nsx-t-2-4-a-landmark-release-in-the-history-of-nsx.html/
VMware has just released a new document to perform a migration from NSX-V to NSX-T leveraging the NSX-T Datacenter Migration Coordinator. Click to access nsxt_24_migrate.pdf Happy reading.
Prerequisites The VMs must be hosted on hypervisors that have been added to the NSX-T Data Center fabric. The fabric nodes must have NSX-T Data Center management plane (MPA) and NSX-T Data Center control plane (LCP) connectivity. The fabric nodes must be added to a transport zone. A logical switch must be created. Steps: In … Explore: Connecting a Virtual Machine to a NSX-T Logical…
When I first tackled NSX-T, like many, I was concerned about IO/Packet flow. Based on feeding my own curiosity while preparing my production environment for NSX-T I decided to write this article. Below you will find high level overview of components and the two tier routing topology. Routing can be defined in the following directions: … Explore: NSX-T Routing 101
NSX-T Manager Controller provides the graphical user interface (GUI) and the RESTful API for creating, configuring, and monitoring NSX-T components, such as logical switches. NSX-T Manager Controller implements the management plane for the NSX-T infrastructure. It provides an aggregated system view and is the centralized network management component of NSX-T. It provides a method for … Explore: NSX-T Component Overview
