Within VMware there are 3 methods around VLAN tagging. They are EST, VST and VGT.<\/p>\n

Below shows the differences between the 3,<\/p>\n\n\n\n\n\n\n
Type<\/strong><\/td>\nPhysical (VNIC)<\/strong><\/td>\nVirtual (vSwitch)<\/strong><\/td>\n<\/tr>\n

VGT<\/td>\nTrunk port<\/td>\nTrunk port<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

EST<\/h2>\n

Within EST (External Switching Tagging) VLAN tags are not handled[1]. The physical switchport is configured as an access-port and no vlan id is configured on the port-group.  Traffic is sent to onto the port group without any vlan tagging occurring.<\/p>\n

VST<\/h2>\n

Within VST (Virtual Switch Tagging) the physical switchport is configured as a trunk port. The port-group is then configured with a VLAN ID of 1-4094. Traffic is received on the vnic tagged, the VLAN tag is then removed and the traffic sent onto the corresponding port-group untagged.<\/p>\n

VGT<\/h2>\n

Within VGT (Virtual Guest Tagging) only vlan tagged traffic is handled. The physical switchport is configured as a trunk port and the port-group is then configured with a VLAN ID of 4095 (All). Traffic is received on the vnic tagged. The traffic is then sent onto the port-group still tagged.<\/p>\n
