    • In one embodiment, in response to receiving a notification to enter a packet filtering mode of operation for a NIC operating a link to a hub/switch in a normal mode of operation at one operating speed, a lower power consuming operating speed is re-negotiated with the hub/switch for the NIC to operate the link in the packet filtering mode. In another embodiment, another link to the hub/switch through another NIC is operated in the packet filtering mode at a lower power consuming speed, in place of the original link and NIC instead. In yet another embodiment, the lowest power consuming NIC among a number of jointly operating NICs is operated in the packet filtering mode, with the remaining NICs being shut down.
    • 在一个实施例中,响应于在一个操作速度下接收到以正常操作模式操作到集线器/交换机的链路的NIC进行包过滤操作模式的通知,重新协商较低的功耗操作速度 网卡的集线器/交换机以包过滤模式操作链路。 在另一个实施例中,替代原始链路和NIC来代替通过另一个NIC的集线器/交换机的另一个链路以较低的功率消耗速度在分组过滤模式中操作。 在另一个实施例中,多个联合操作的NIC中的最低功耗NIC在包过滤模式下操作,其余NIC被关闭。
