What is the main feature of the vSphere Distributed Switch (vDS)?

The main feature of the vSphere Distributed Switch (vDS) is indeed the ability to provide a single point of configuration for multiple hosts. This centralized management approach enhances operational efficiency when it comes to managing network settings for a cluster of VMware hosts. With vDS, network configurations, policies, and settings can be applied uniformly across all hosts connected to the distributed switch. This means that changes made to the vDS will automatically propagate to all associated virtual machines and hosts, reducing the amount of manual configuration required and minimizing the chances of misconfiguration across different hosts in the vSphere environment.

This functionality is particularly beneficial in large environments where numerous hosts need to maintain consistent network policies, as it streamlines administration and simplifies the overall management of networking resources in a virtualized infrastructure.
