v The adapter cannot be assigned to an adapter team.
v If you are setting up virtual local area networks (VLANs) and packet tagging on
the same adapter, 802.1p/802.1Q tagging must be enabled on the IBMSet
Advanced tab.
If your network infrastructure devices do not support IEEE 802.1p or you are not
sure, you can still define filters and send packets as high priority. While 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 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 filter.
To effectively use HPQ, the adapter cannot be assigned to an adapter team.
Virtual LAN mode: A virtual LAN is a logical grouping of network devices put
together as a LAN, regardless of their physical grouping or collision 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 connecting clients to
servers that are geographically dispersed across the building, campus, or enterprise
network.
Typically, VLANs are configured at the switch and any server can be a member of
one VLAN per installed network adapter. Your 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, your 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 network driver interface
specification (NDIS) driver hotfix from Microsoft.
3. In Windows NT, VLANs cannot be implemented on controllers that have been
configured for teaming options. NetWare can support teaming options and
VLANs on the same adapters.
Complete the following steps to join a VLAN from Windows NT 4.0.
1. Create a VLAN on the switch. Use the parameters you assign there to join the
VLAN from the server. Refer to your switch documentation for more
information.
2. Double-click the Network icon in the Control Panel window.
3. On the Adapters tab, select the adapter you want to be on the VLAN and click
Properties.
4. In IBMSet, click Join VLAN. Note that VLANs cannot be assigned to adapters
that are already defined to have an adapter teaming option.
