所有的十兆以太网接口是半双工的工作模式吗？

以前的老式机器是半双工的。现在的机器支持全双工。例如，Cisco Cat2960 IOS12.2(40)SE 默认情况下是半双工，但是可以使用全双工。

Normally, 10-Mb/s ports operate in half-duplex mode

Gigabit Ethernet (10/100/1000-Mb/s) ports support all speed options and all duplex options (auto, half, and full). However, Gigabit Ethernet ports operating at 1000 Mb/s do not support half-duplex mode.
