The 2 VMs (one is a virtual port and 2nd is windows server 2008 R2)are on the same virtual switch (vswitch1 in vsphere esx configuration with virtual switches.jpg). Hence, the communication is between the 2 VMs and hence the traffic does not leave the ESX host and does not go to physical NIC. The attached file vsphere esx configuration with virtual switches.jpg explains my vswitch. The attached file vmxnet3 with wireshark.jpg shows traffic but no vlan header is present. The following link http://www.vmware.com/files/pdf/virtual_networking_concepts.pdf explains the vlan infrastructure. On pages 7 and 8 they have mentioned about the VST and VGT mode. Do you guys think I will need some 802.1q driver to be installed to detect vlan?
