NSX Port Requirements

Planning for successful NSX deployment should include complete understanding of the communication which happens between different NSX components,

One of the recommended (not mandatory) pre-requisites for successful NSX deployment is to have check list to ensure that you open all the requirement communication between different NSX components.
This helps in smooth deployment of NSX & saves time from doing any troubleshooting to identfy where the problem exists.
Ensure you refer to the VMware KB Article & confirm the required ports which needs to be opened.
