During the installation of a transport node in VMware NSX-T Data Center, two components are involved in the logical switching and N-VDS configuration: Open vSwitch and nsx-vswitch.
Open vSwitch: Open vSwitch is an open-source, multilayer virtual switch that is used to connect virtual machines (VMs) to the physical network. Open vSwitch can be used as a standalone switch or as a component of a larger virtualization deployment, such as VMware NSX-T. Open vSwitch provides advanced networking features, including support for virtual LANs (VLANs), Link Aggregation Control Protocol (LACP), and Network Address Translation (NAT).
nsx-vswitch: nsx-vswitch is a component of VMware NSX-T that provides virtual switch functionality within the ESXi host. nsx-vswitch is designed to work with Open vSwitch to provide logical switching functionality in a virtualized environment. The N-VDS (NSX Virtual Distributed Switch) is created and managed by the nsx-vswitch component. The N-VDS provides connectivity to VMs and NSX-T components such as logical routers, logical switches, and distributed firewall.
Therefore, during the installation of a transport node in VMware NSX-T Data Center, Open vSwitch provides the underlying virtual switch functionality, while nsx-vswitch creates and manages the N-VDS that provides logical switching functionality. The other options listed in the question, etherswitch, nsx-opsAgent, and vdl2, are not involved in the logical switching and N-VDS configuration during ESXi transport node installation in VMware NSX-T Data Center.
