3.1.4.2 GbE Interface
In addition to supporting 10 Gb/s operations, the 82598 also supports a 1 GbE Interface. To support 1
GbE operation, one of the XAUI Lanes operates at 1.25 Gb/s. All the other 3 XAUI lanes are powered
down to electrical idle (output level <50 mV).
3.1.4.3 Auto Negotiation and Link Setup Features
The method for configuring the link between two link partners is highly dependent on the mode of
operation as well as the functionality provided by the specific physical layer device.
3.1.4.3.1 Link Configuration
The 82598 network interface meets industry specifications for:
• 10 GbE – XAUI (802.3ae)
• 10 GbE – CX4 (802.3ak)
