Using LACP in VCF 9 deployment
When using the VCF Planning and Preparation Workbook excel spreadsheet, you can not choose to use LACP and LAGs for your network design and deployment you will have to configure that your self in the JSON file, used for deployment.
I use the VCF Planning and Preparation Workbook and the VCF.JSONgenerator powershell scripts to generate the JSON file, this will be my template for the deployment and then I will modify the JSON so is configures LACP/LAGs on the network on the Distributed Switche(s).
The LACP LAG is only supported for the NSX part not vSAN.
I have removed the scripts there are some resources here for the configurations:
