v The adapter cannot be assigned to an adapter team. v If you are setting up 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 High Priority 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 filter. 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. 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 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. 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. 2. In the Control Panel window, double-click the Network icon. 3. On the Adapters tab, select the adapter that 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. 76 Hardware Maintenance Manual: xSeries 220 Type 8646

If your network infrastructure devices do not support IEEE 802.1p or you are not

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.
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
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.
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.
2.
In the Control Panel window, double-click the
Network
icon.
3.
On the Adapters tab, select the adapter that 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.
