An NSX administrator is using ping to check connectivity between VM1 running on ESXi1 to VM2 running on ESXi2. The ping tests fail. The administrator knows the maximum transmission unit size on the physical switch is 1600.
Which command does the administrator use to check the VMware kernel ports for tunnel end point communication?

  • A. vmkping ++netstack=geneve -d -s 1572 <destination IP address>
  • B. vmkping ++netstack=vxlan -d -s 1572 <destination IP address>
  • C. esxcli network diag ping –H <destination IP address>
  • D. esxcli network diag ping -I vmk0 -H <destination IP address>

Selected Answer: A
vmkping is the command used to test network connectivity for VMware kernel ports (vmk interfaces). The ++netstack=geneve option specifies that the Geneve (Generic Network Virtualization Encapsulation) protocol is being used. Geneve is the protocol used in NSX-T for overlay tunneling between ESXi hosts. -d enables the Don't Fragment (DF) bit, which ensures that the packet will not be fragmented. This is important because you're testing with a specific MTU size. -s 1572 sets the packet size to 1572 bytes. This accounts for the overhead of the encapsulation and leaves the packet size of 1600 bytes (the maximum allowed by the physical switch), considering the Geneve header.
