What are the three different ways to determine how VLANs are controlled in a virtual switch configuration?
The three different ways to determine how VLANs are controlled in a virtual switch configuration are:
1. Inside the VMkernel
2. At the guest operating system layer
3. On the external physical switch
Virtual Switch Tagging (VST) Modes
VST Mode: The main difference between the VST modes in virtual switch configuration is where the VLAN tags are applied - externally. The VLAN tags are added by the external physical switch based on its configuration.
Explanation: In VST mode, the tags are applied on the external physical switch. This means that the VLAN tags are processed and interpreted by the external switch before being forwarded to the virtual machines.
In VST mode, the virtual switch forwards the frames from the virtual machines to the external switch without VLAN tags. The external switch then adds the appropriate VLAN tags based on its configuration and forwards the frames further.
