Municipal ESXi hosts must carry overlay traffic for agency VMs. Which host-switch building block does NSX-T use for that overlay and NSX VLAN traffic?
Select an answer to reveal the explanation.
Short Explanation
Overlay frames need an NSX-aware switch on the host—either the N-VDS or a VDS that NSX has prepared. A leftover standard switch, a Horizon gateway, or a sensor filter is not that host switch.
Full Explanation
NSX-T programs a host switch on each ESXi transport node: historically the N-VDS (NSX Virtual Distributed Switch), and in the vSphere 7 / NSX-T 3.x era an NSX-prepared VDS can play the same role. That switch carries Geneve overlay and NSX VLAN-backed traffic. An unprepared vSphere Standard Switch is host-local vSphere networking only. Horizon UAG and Carbon Black sensors are not NSX host switches.
