VCF Upgrade Failure with Static NSX-T Routing

April 29, 2022 / Martijn / 0 Comments

Do you have a VMware Cloud Foundation infrastructure that’s using NSX-T to statically route network traffic between the NSX-T Edges and the physical network? If so, you can be faced with this error when attempting to upgrade VCF via the SDDC Manager:

2022-04-19T18:28:58.205+0000 ERROR [vcf_migration,0000000000000000,0000] [c.v.e.s.o.model.error.ErrorFactory,pool-5-thread-12] [43TCDO] TIER_0_ROUTE_DISTRO_UPDATE_POST_VALIDATE_FAILED Post-validate of tier-0 T0
route distribution types update failed com.vmware.evo.sddc.orchestrator.exceptions.OrchTaskException: Post-validate of tier-0 T0 route distribution types update failed

This is a quick post with the solution to that error. It seems like VCF is mostly designed for dynamic routing via BGP (which makes total sense), with which routing redistribution is necessary … Read more

Integrating ServiceNow with Network Insight

November 19, 2018 / Martijn / 0 Comments

In a previous post, Integrating vRealize Automation with Network Insight, I covered how greenfield applications can be automatically pushed into vRealize Network Insight to provide application context with the analytics of Network Insight. This post is about importing brownfield into Network Insight to get insights into the behavior of your existing applications. Specifically, importing CMDB information from ServiceNow.

Disclaimer: This is something I built, it is not officially supported by VMware.

CMDB

In the case of existing applications, your Configuration Management Database (CMDB) should be your source of truth. There are a lot of CMDB products out there, … Read more

VMworld EU 2018 – My Session Picks

October 1, 2018 / Martijn / 0 Comments

It’s that time of the year. VMworld Europe is rapidly heading for us and the schedule builder has been opened! If you’re going to VMworld for technical training and are planning on visiting breakout sessions, keep the list below in mind. I’ve laid out my picks when it comes to Networking & Security related (NSX Data Center & SD-WAN, Network Insight, and AppDefense).

These picks are based on the presenters and knowing they have a good story and some inside knowledge that they’re going to be awesome. For instance, Accelerate App Security and Availability with vRealize Network Insight [SAI2555BE] is … Read more

Using PowervRNI to configure SNMP settings on data sources

September 3, 2018 / Martijn / 0 Comments

Version 1.2 of PowervRNI was just released and it contains 2 new cmdlets:

Get-vRNIDataSourceSNMPConfig
Set-vRNIDataSourceSNMPConfig

You can use these cmdlets to see and update SNMP configuration on specific data sources. All Arista, Brocade, Cisco, Dell, and Juniper devices are data sources where SNMP can be enabled for richer data collection. This basically turns on interface counter collections, so you can have pretty graphs like this:

Examples

To give you an idea of how to use these new cmdlets, check out the examples below. Of course, there is also documentation available in the module itself, viewable via the Get-Help cmdlet.

vRealize Automation and NSX with App Isolation: Internal error

July 30, 2018 / Martijn / 0 Comments

My colleague Erik Scholten (vRealize specialist) was building a demo environment for a customer this week. In this environment, he wanted to demonstrate vRealize Automation (vRA) in all its glory and have NSX coupled to it so vRA could use NSX to micro-segment rolled out blueprints using the App Isolation option.

NSX is pretty easy to get off the ground for first use, which he did himself with ease. All that’s needed for one to be able to use the distributed firewall to micro-segment, is to deploy NSX Manager, connect it to vCenter and prepare the ESXi hosts. NSX was … Read more

Learning NSX SD-WAN by VeloCloud – Orchestrator Configuration Basics

June 11, 2018 / Martijn / 0 Comments

This post is a part of my NSX SD-WAN by VeloCloud series to dive deeper into the acquisition of VeloCloud by VMware, late last year. In an earlier post, I explained the concepts behind the architecture of NSX SD-WAN and with this post, I will dive into the VeloCloud Orchestrator (VCO) to see what you need to configure to generate an SD-WAN network. Please note that the Orchestrator can be used to monitor and troubleshoot the SD-WAN as well, I will cover those topics in a future post.

VeloCloud Orchestrator (VCO) – What is it?

The VCO is the management … Read more

NSX-v 6.4.1 Released – Extended HTML5, vSphere 6.7 support & more

May 25, 2018 / Martijn / 2 Comments

NSX for vSphere 6.4.1 has been released and it brings a couple of good nuggets. Most of all, it is now compatible with vSphere 6.7 – so if you want to go to vSphere 6.7 and NSX was holding you back, start your upgrade engines!

HTML5 UI Extended

It fills me with joy to see this happening – 6.4.1 brings a bunch of new functionality to the HTML5 UI instead of the old vSphere-Client UI. The additions are:

Distributed Firewall Management
The Service Composer: Security Groups, Policies and Tags.
SpoofGuard Management
IPFIX Configuration & Flow Monitoring
Groups & Tags: all
