Forcing Speed and Duplex of on-board network interface e1000g on T2000, T5120, and T5220 with ndd
By default the e1000g network interface is set to auto-negotiation enabled, 1Gbps full-duplex.
# ndd -set /dev/e1000g<instance> adv_autoneg_cap 0
# ndd -set /dev/e1000g<instance> force_speed_duplex <value>

1 |
10Mb/s, half-duplex |

2 |
10Mb/s, full-duplex |

3 |
100Mb/s, half-duplex |
|
4 |
100Mb/s, full-duplex |
I found this while reading the hardware platform guide for T5120. “force_speed_duplex” is not available for other types of network interfaces.
