Managing and troubleshooting virtual guests network connectivity issues is quite difficult, if you do not have right information about upstream switches. It is crucial to know where are Nutanix hosts are connected to, switch name, location, switch port number. Nutanix AHV leverages OVS (Open VSwitch) to manage AHV hosts and Guest OS network connectivity. OVS can use LLDP (Link Layer Discovery Protocol) to pull information from physical switches. LLDP is automatically enabled on Nutanix AHV. To have LLDP discovery working you have to have LLDP enabled on the network port switches. If you have LLDP enabled on network switch Nutanix AHV will automatically pull switch info and you can see it in Prism.
