Configuring the Working Mode of a Combo Interface

Configuring the Working Mode of a Combo Interface

# Configure GE1/0/1 to work in electrical mode.
<HUAWEI> system-view
[HUAWEI] interface gigabitethernet 1/0/1
[HUAWEI-GigabitEthernet1/0/1] combo-port copper

To configure the working mode of a combo interface, run the combo-port { auto | copper | fiber } command in the combo interface view.

  • When the auto mode is specified, the system checks whether the combo optical interface has an optical module installed, and selects the interface working mode as follows:
    • When the electrical interface is not connected, the combo interface works as an optical interface if the combo optical interface has an optical module installed.
    • When the electrical interface is connected using a network cable and the combo interface is Up, the combo interface works as an electrical interface even if the combo optical interface has an optical module installed. However, the combo interface works as an optical interface after the device restarts.
    • When the electrical interface is connected using a network cable and the combo interface is Down, the combo interface works as an optical interface if the combo optical interface has an optical module installed.

    In summary, when the auto mode is specified and the combo optical interface has an optical module installed, the combo interface works as an optical interface after the device restarts.

  • You can forcibly specify the working mode of the combo interface based on the peer interface type. If the local combo electrical interface is connected to a peer electrical interface, configure the combo interface to work in copper mode. If the local combo optical interface is connected to a peer optical interface, configure the combo interface to work in fiber mode.
