What type of switch is utilized in NSX-T to enable Layer 2 connectivity?

In NSX-T, a Logical Switch is utilized to enable Layer 2 connectivity in a virtualized environment. Logical Switches are an abstraction of the traditional network switches and are designed to connect virtual machines (VMs) to each other and to services within the NSX-T environment. Each Logical Switch corresponds to a unique Layer 2 broadcast domain, allowing VMs to communicate even when they reside on different underlying physical switches or hosts.

When a Logical Switch is created in NSX-T, it facilitates the forwarding of frames at Layer 2 without the need for physical network infrastructure changes. This capability is particularly valuable for multi-tenant environments, where tenants can have isolated Layer 2 segments while still sharing the same physical infrastructure.

This design enhances the agility and scalability of network provisioning because Logical Switches can be created, modified, or removed dynamically based on the needs of applications, without affecting the underlying physical networking. The abstraction of Logical Switches allows for seamless Layer 2 connectivity, supporting various network configurations and deployments in an NSX-T environment.
