Intel® Advanced Network Services (Intel® ANS) VLANs

Virtual Local Area Network (VLAN) is a logical grouping of hosts. This grouping allows them to communicate as if they were on the same LAN, regardless of the physical topology of the network.

VLANs offer the ability to group computers together into logical workgroups. This can simplify network administration when connecting clients to servers that are geographically dispersed.

Typically, VLANs consist of co-workers in the same department but in different locations or a cross-functional team working on a joint project.

Advantages of VLANs

  • Improve network performance
  • Limit broadcast storms
  • Improve LAN configuration updates (adds, moves, and changes)
  • Minimize security problems
  • Ease your management tasks

VLAN types
Two basic types of VLANs exist:

  • Tagged VLANs are based on the IEEE 802.1Q specification. Each packet has a 4-byte tag added to the packet header. The switch must support IEEE 802.1Q tagging and be properly configured. Check your switch documentation for the correct switch configuration.
  • Untagged or Port-based VLANs are statically configured on the switch. They are transparent to connected devices.

Implementation considerations

  • Intel® software supports a maximum of 64 VLANs per network port or team.
  • To set up IEEE VLAN membership (multiple VLANs), the adapter must be attached to a switch with IEEE 802.1Q VLAN capability.
  • VLANs can co-exist with teaming (if the adapter supports both). The team must be defined first, then you can set up your VLAN.
  • You can set up only one untagged VLAN per port or team. You must have at least one tagged VLAN before you can set up an untagged VLAN.
  • After creating the VLAN, the adapter associated with the VLAN can have a momentary loss of connectivity
  • A VLAN cannot be removed if a virtual NIC is bound to it.
  • If VLANs are assigned to an adapter, the Priority & VLANs option on the Advanced properties tab is enabled and cannot be disabled until all VLANs are removed from the adapter.
  • If you change a setting under the Advanced tab for one VLAN, it changes the settings for all VLANS using that port.
  • Intel® Advanced Network Services (Intel® ANS) VLANs are not supported on adapters and teams that have VMQ enabled. But, VLAN filtering with VMQ is supported via the Microsoft Hyper-V* VLAN interface. For more information see Microsoft Hyper-V virtual NICs on teams and VLANs in the adapter user guide.
  • You can have different VLAN tags on a child partition and its parent. Those settings are separate from one another, and can be different or the same. The VLAN tag on the parent and child must be the same if you want the parent and child partitions to be able to communicate through that VLAN. For more information, see Microsoft Hyper-V virtual NICs on teams and VLANs in the adapter user guide.

Windows Server 2012* NIC teaming
Windows Server 2012* adds support for NIC teaming, also known as Load Balancing and Failover (LBFO). Intel ANS teaming and VLANs are not compatible with Microsoft LBFO teams. Intel® PROSet blocks a member of an LBFO team from being added to an Intel ANS team or VLAN. You should not add a port that is already part of an Intel ANS team or VLAN to an LBFO team. Adding a port can cause system instability.

Supported adapters
Intel® Ethernet Adapters supports configuring VLANs, in any version of Windows, where full software support is available for that adapter.

Support for Intel® PROSet and Intel ANS provides information on adapters with full support for Windows 7* and later.

Intel® PRO/100 and PRO/1000 adapters, that plug into PCI* or PCI-X* slots, do not support Intel ANS VLANs in any version of Windows* after Windows Vista* and Windows Server 2008*. After these versions, only the Windows inbox driver from Microsoft is available.

Installing Intel ANS support for VLAN configuration in Windows*
You must install Intel® PROSet and ANS to enable VLAN configuration on Intel® Ethernet devices. You cannot configure VLANs if only the base drivers are installed. Installation of both Intel PROSet and Intel ANS are enabled by default when installing Intel® Network Connections software.

Using the install wizard, select both Intel® PROSet for Windows* Device Manager and Advanced Network Services on the Setup Options screen.

Configuring VLANs

  1. Go to Windows Device Manager.
  2. Open the properties of the port where you want to configure the VLAN.
  3. Go to the VLAN tab.
  4. Click the New button.
  5. Type the VLAN ID number into the VLAN ID box. The IDs configured on the port must also be configured on the switch.
  6. Accept the VLAN name entered by default or type in a new name.
  7. Click OK.
