VMware vRealize Network Insight (vRNI) – Part 2 – Configuration

Reading Time: 4 minutes

In my last vRealize Network Insight article (VMware vRealize Network Insight (vRNI) – Part 1 – Installation) we covered the initial installation of the on-premises Platform and Proxy/Collector appliances.

Following on from the installation we will begin looking at how we actually add data sources to vRNI in readiness for application discovery and data flow analysis.

In this article, we will add a vCenter Server and an NSX-T Manager.

VMware vRealize Network Insight (vRNI) – Part 1 – Installation

Reading Time: 5 minutes

In a nutshell, vRealize Network Insight delivers intelligent operations for software-defined networking and security. It enables customers to build an optimised, highly-available, and secure network infrastructure across multi-cloud environments. It accelerates micro-segmentation planning and deployment, enables visibility across virtual and physical networks, and provides operational views to manage and scale the VMware NSX deployments.

VMware NSX-T Manager FQDN Registration

Reading Time: 3 minutes

By default, NSX-T transport nodes access NSX-T Manager nodes via their IP address, however, changing this behaviour so that the NSX-T Manager FQDN is used instead is an easy fix and is implemented by a simple REST API call.

FQDN registration is an NSX-T Multisite requirement. As such, FQDN registration is not required for single-site deployments.

In the scenario whereby a customer needs to failover NSX-T operations to a secondary site (by deploying a new NSX-T Manager and restoring from backup), the NSX-T Manager(s) and Cluster VIP address will likely change unless they have implemented stretched-L2. As such, the NSX-T Manager(s)/Cluster FQDN needs to be registered with all NSX-T transport nodes and, once a new NSX-T Manager is deployed to the secondary site and restored from backup, DNS can be amended, and management operations restored.

VMware NSX-T – Modifying the Default Admin Password Expiration

Reading Time: < 1 minute

In NSX-T, the Admin and Audit user passwords for both the NSX Manager and NSX Edge appliances expire, by default, after 90 days. When these passwords expire, you will not be able to log in and manage your NSX-T components. This includes any API calls where administrative credentials are required.

In this article I detail the simple process of amending the expiration period or, if so required, removing the password expiration altogether (the latter being perfect for POC and/or lab environments).

North East VMUG 2019 - Gareth-Lewis

North East England VMUG – 26th September 2019

Reading Time: 4 minutes

That didn’t disappoint! I’ve wanted to visit the North East England VMUG for sometime, so being asked to present at the user group made it all the more special. As I sit here in Newcastle International Airport waiting for my flight home, I thought I’d summarise the event for those who’ve never been to a VMUG event, are thinking of doing so in the future, or are thinking of speaking at a local VMUG.

VMware NSX-T Data Center Migration – Part 2 – NSX for vSphere (NSX-V) Preliminary Checks

Reading Time: 6 minutes

Welcome to the second article in the series detailing a migration of VMware NSX Data Center for vSphere (NSX-V) to NSX-T Data Center. In this article I focus on the preliminary checks to ensure the NSX-V environment is fit for migration.

In part 1 (VMware NSX-T Data Center Migration – Part 1 – Deploy Manager Appliance) I covered the process of deploying the NSX -T Data Center Manager Appliance, as well as a number of prerequisite tasks required to prepare the new NSX-T environment for the eventual migration (coming in part 3).

In this article I detail a number of preliminary checks within the NSX-V environment (including ESXi hosts, vSphere Distributed Switches, VXLAN configuration, VTEP, NSX Controllers, Edge Services Gateways, etc.) to ensure all is well prior to the migration process itself. Where any issues are identified, these must be resolved prior to the migration process.
