Can I add both an electrical interface and an optical interface to an Eth-Trunk

You can add both an electrical interface and an optical interface to an Eth-Trunk. This is because the selected interface is irrelevant to the interface mode.

Why an interface can be configured as both optical and electrical interfaces
When a 1000M optical interface connects to an electrical module, it works as an electrical interface. However, the interface retains the configuration of the optical interface. When configuration is performed on the electrical interface, the interface has the configurations of both optical and electrical interfaces. When you remove the electrical module and connect the 1000M optical interface to an optical module, the 1000M optical interface works as an optical interface. However, the interface retains the configuration of the electrical interface. The configurations of optical and electrical interfaces do not conflict. Before deleting the electrical interface configuration from the 1000M optical interface, you must connect the 1000M optical interface to an electrical module. A combo interface is a multiplexing interface and can connect to optical or electrical media. You can differentiate the physical configuration including the rate, duplex mode, auto-negotiation, and flow control according to port media type fiber/copper in the configuration file. By default, a combo interface adapts to the optical or electrical media. The media configuration is delivered automatically to the combo interface and the combo interface configuration and the media configuration do not conflict. Before deleting the media configuration, switch the combo interface to work in media mode. NOTE: You can run the combo-port { copper | fiber } command to configure the interface to work as an electrical or optical interface. If the combo interface works as an electrical interface, run the combo-port fiber command to configure the interface to work as an optical interface. If the combo interface switches to another operation mode, the original configuration exits but does not work.

Can I add interfaces with different bandwidths to an Eth-Trunk
Interfaces with different bandwidths cannot be added to an Eth-Trunk.

Configure Eth-Trunk on the S1728GWR-4P switch
Configure an Eth-Trunk on an S1728GWR-4P switch as follows: 1. Add a trunk. a. Choose Interface > Trunk > Static. b. Select Add from the Action drop-down list box and configure parameters to add a trunk. c. Click Apply. 2. Set trunk properties. a. Choose Interface > Trunk > Static and select Config from the Action drop-down list box. b. Modify the interface configuration as required. c. Click Apply. 3. Add trunk members. a. Choose Interface > Trunk > Static and select Add member from the Action drop-down list box. b. Select a trunk ID and specify a port number range of which the interfaces are added to the trunk. c. Click Apply.

How Do I Add Member Interfaces to an Eth-Trunk?
Before adding a new member interface, ensure that the type of the new member interface is the same as that of other member interfaces and there is no configuration on the new member interface. Run the shutdown command in the interface view to configure the new member interface in Down state. If the new member interface that joins the Eth-Trunk is not configured to be Down, a temporary loop may occur. As a result, services are affected. Run either of the following commands to add the new member interface to the Eth-Trunk. Run the eth-trunk trunk-id command in the interface view. Run the trunkport interface-type { interface-number1 [ to interface-number2 ] } &<1-8> command in the Eth-Trunk interface view. After member interfaces at both ends join the Eth-Trunk, run the undo shutdown command in the interface view to enable the new member interfaces.

Configure link aggregation among cards on S series switches.
Note the following when you configure link aggregation on S series modular switches: 1. Interfaces of different Ethernet types or rates cannot be added to the same Eth-Trunk. For example, you cannot add GE interfaces and FE interfaces to the same Eth-Trunk, but you can add GE electrical interfaces and GE optical interfaces to the same Eth-Trunk. 2. The two ends of the Eth-Trunk must use the same number of interfaces, interface rate, duplex mode, and flow control configuration. 3. The remote interfaces directly connected to the local Eth-Trunk member interfaces must also be added to an Eth-Trunk; otherwise, the two ends cannot communicate. 4. When you connect the two devices, ensure the link aggregation modes on the two devices are the same. 5. There are strict limitations in link aggregation between boards.
