I has been testing the vlan tagging by using F5 VM and vmware vSwitch. Does it support?
Yes. The F5 fully supports VLAN tags. By default when you create a VLAN on an F5, you specify the interface as tagged or untagged. Tagged means you specify the VLAN number.
The VM means Virtual Machine? It uses the same code as the physical boxes.
1.1 (tagged, serivce)
what does service mean? how to configure it?
1.1 is the interface name/numbering used as tagged interface with services.
Can you share screenshot having this info to inform you better.
