How To Verify if SDDC Bringup is AVN Enabled in VCF?

Recently I saw an interesting thread on slack where one of the consultant was seeing deploy button grayed out for VRSLCM deployment. Consultant was not aware if the management domain bringup was AVN enabled or not. 

AVN was first introduced in VCF 3.9 and it enabled deploying vRealize components on logical segments instead of VLAN backed portgroup. AVN brought many enhancements with Cloud Foundation. Please read this Article to know more about AVN.

Since AVN enablement is optional and you can chose not to use it during SDDC bringup This is controlled via a parameter in VCF configuration workbook and ca be enabled later also.

Now the question is how to verify whether or not a SDDC bringup is AVN enabled bringup. There are couple of ways to verify this.

1: Through PowerVCF

PowerVCF is a PowerShell module to interact with SDDC Manager and the VCF stack. If you have PowerVCF is installed, you can connect to sddc-manager using below command:

# Connect-VCFManager <sddc-manager-fqdn> <sso-credentials>

and then run command: Get-VCFApplicationVirtualNetwork

2: Querying VCF Database

Although PowerVCF method is sufficient to verify AVN thing, optionally this can be queried from VCF Database.

3: From feature.properties file

For a AVN enabled bringup, you will see a property feature.vcf.avn.greenfield=true in feature.properties file

root@sddc-manager [ ~ ]# cat /opt/vmware/vcf/commonsvcs/conf/feature.properties | grep avn
feature.vcf.avn.greenfield=true

And that’s it for this post.
