It is possible for ESXi host to use multiple TCP/IP stacks. In that case to validate connectivity between two ESXi hosts use:

  1. Get list of network stacks using:
    esxcli network ip netstack list
  2. Understand which vmkernel port is using which TCP/IP stack using:
    esxcli network ip interface list | grep -i 'name\|stack'
  3. ping with appropriate stack name to remote machine on corresponding network using:
    ping -s <stack-name> <remote-ip>
    For example
    ping -S "vmotion" 10.2.23.57
