10/100 Mbps electrical Ethernet ports can operate in full-duplex, half-duplex or
auto-negotiation mode, so can a 10/100/1,000 Mbps electrical Ethernet port. However,
when the port rate is set to 1,000 Mbps or auto, the duplex mode of the port can only be
set to full (full duplex) or auto (auto-negotiation). A 100 Mbps/1,000 Mbps optical
Ethernet port operates in full duplex mode even if it is configured to operate in the
auto-negotiation mode. A 10 Gbps optical Ethernet port can only operate in full duplex
mode.
The duplex mode of Ethernet ports defaults to auto (auto-negotiation).
Caution:
For ports coupled with photoelectric transducers, set the duplex mode to
auto-negotiation mode. Otherwise, the status check for the port may be abnormal.
Only the GP48 interface board offers 100/1000 Mbps optical ports. By default, such
an optical port operates at 1000 Mbps in full-duplex mode. If its rate is configured as
100 Mbps, you are recommended to configure it to operate in full-duplex mode.
Otherwise, the auto-negotiation information of the port will be wrong.
Only the GP48 interface board supports speed (10/100/1000 Mbps) and duplex
mode auto-negotiation for photoelectric transceiver modules. For the function to
work, you must ensure that the modules are 1000_BASE_T photoelectric
transceiver modules certified by H3C.

1.2.5 Setting Speed on the Ethernet Port

You can use the following command to set the speed on the Ethernet port. If the speed
is set to auto-negotiation mode, the local and peer ports will automatically negotiate the
port speed.
Perform the following configuration in Ethernet port view.
