If this happens, check that the agents are running on the host. If it is, check the advanced settings virtual switches and look for any errors like Partial Success, or other information. If a VM is not able to communicate on a specific host, check that the segment is present, if it isn’t showing on the host, go into the GUI, and check the N-VDS segment is present. Vmkping ++netstack=vxlan -s 1572 -d # using 1572 data bytes, and ping destination TEP If 1572 fails try 1472 if that works, the overhead for the overlay hasn’t been configured. GENEVE adds 72 bytes to a 1500 byte data packet. Try 1572 if 1575 fails This is the minimum size needed to support GENEVE. Ping destination TEP interface from the source host vmkping ++netstack=vxlan -s Vxlan is used by host rather than GENEVE. Vmk50 is for intra-tier networking/routing and containers.
