Default VLAN Tagging
When default VLAN tagging is configured on a VF, a VLAN ID is automatically added
to and removed from every packet sent and received over the VF.
To configure a default VLAN tag:
1. Power off the VM before proceeding to the next step.
2. Edit the <vm-name>.vmx file corresponding to the VM from the vmfs Datastore
under /vmfs/volumes/Datastore/<VM_DIR>/.
3. Append the following line:
pciPassthru<X>.defaultVlan = "<vlan_id>"
where <vlan_id> is the required VLAN ID value for the pass-through VF <X>
assigned to the VM.
4. Power on the VM.
Virtual Guest Tagging
When VGT is configured, a guest operating system can configure any VLAN ID using
the native VLAN configuration method in the guest operating system.
To enable VGT:
1. Configure the special VLAN ID 4095 using the steps listed in “Default VLAN
Tagging” on page 1001.
2. Use the native method in the guest operating system to configure the required
VLAN ID (for example, vconfig in the Linux guest operating system).
Configuring a Static MAC for a VF
A MAC address is automatically configured by ESXi for each VF. This default MAC
address may be modified using the following steps:
1. Power off the VM before proceeding to the next step.
2. Edit the <vm-name>.vmx file corresponding to a VM from the vmfs Datastore
under /vmfs/volumes/Datastore/<VM_DIR>/.
3. To configure the MAC address “00:50:56:00:00:02” on the first VF assigned to this
VM, append the following lines:
pciPassthru0.MACAddressType = "static"
pciPassthru0.MACAddress = "00:50:56:00:00:02"
4. Power on the VM.
