Queue (HPQ) does not provide the precise priority levels of 802.1p tagging, it does
assign traffic as either high or low priority and sends high-priority packets first.
Therefore, if there are multiple applications on a system that is sending packets, the
packets from the application with a filter are sent out first. HPQ does not change
network routing, nor does it add any information to the packets.

To assign HPQ, you can specify it using Priority Packet when you create or assign a

To effectively use HPQ tagging, the adapter cannot be assigned to an adapter team.
Virtual LAN Mode:
A virtual LAN (VLAN) is a logical grouping of network devices
that are put together as a LAN, regardless of their physical grouping or collision
domains. Using VLANs increases network performance and improves network
security.
domains. Using VLANs increases network performance and improves network
security.
VLANs offer you the ability to group users and devices together into logical
workgroups. This can simplify network administration when you are connecting
clients to servers that are geographically dispersed across a building, campus, or
enterprise network.

Normally, VLANs are configured at the switch, and any computer can be a member of
one VLAN per installed network adapter. The Ethernet controller supersedes this by
communicating directly with the switch, enabling multiple VLANs on a single
network adapter (up to 64 VLANs).

To set up VLAN membership, the Ethernet controller must be attached to a switch
that has VLAN capability. You also need to use Windows NT 4.0 or later, or Novell
NetWare 4.1x or later.

Notes:
1.
Windows NT versions prior to 4.0 do not support VLANs.
2.
VLANs require NT 4.0 with Service Pack 3.0 and the NDIS driver hotfix from

In Windows NT, VLANs cannot be implemented on controllers that have been

To join a VLAN from Windows NT 4.0:
1.
Create a VLAN on the switch. Use the parameters that you assign there to join the
VLAN from the server. Refer to your switch documentation for more information.
