## Standards

- IEEE 802.1p: Priority Queuing (traffic prioritizing) and Quality of Service levels
- IEEE 802.1Q: Virtual LAN identification
- IEEE 802.3ab: Gigabit Ethernet over copper
- IEEE 802.3ac: Tagging
- IEEE 802.3ad: Link Aggregation (static mode is supported on indicated Intel adapters)
- IEEE 802.3u: Fast Ethernet
- IEEE 802.3x: Flow Control
- ACPI: Advanced Configuration and Power Management
- PCI: system bus specification: 32-bit, 33/66 Mhz (any combination, unless otherwise noted)

More information on IEEE 802 standards available at http://www.ieee802.org.

IEEE 802.3ac VLANs:

VLANs require VLAN capable switches either implicit (switch only) or explicit (IEEE 802.3ac). IEEE 802.3ac VLANs allow multiple VLANs per adapter or team since both the switch and adapter use a tag in the packet header to sort VLANs.

## Ethernet MAC Addresses

### Single-Port Adapters

The Ethernet address is printed as a hexadecimal number on the identification sticker on the front of the card.

### Integrated Adapters

On a system with the LAN integrated on the motherboard, the identification sticker is usually located on the motherboard near the network connector.
