Does the combo port on an S series switch support 100M optical modules
For S series switches, optical ports of combo ports support 100M optical modules.

What is the combo port on S series switches, and how to use it
For S series switches (except S1700 switches), the meaning and usage of a combo port are described as follows: 1. What is a combo port? A combo port consists of a GE electrical port and a GE optical port on the panel. The multiplexed electrical and optical ports share one internal forwarding port and cannot work at the same time. When one port works, the other one is disabled. You can use the electrical or optical port according to the peer port type. The electrical and optical ports share one interface view. When you enable the electrical or optical port, configure the interface attributes (such as the rate and duplex mode) in the same interface view. 2. How can I identify whether a physical port on a switch is a combo port? a. Identify a combo port based on the port ID on the switch panel. If two ports have the same ID but different transmission media, the two ports are multiplexed as a combo port. b. Run the display interface interface-type interface-number command to display the combo port information. Example: [HUAWEI]display interface GigabitEthernet 0/0/1 GigabitEthernet0/0/1 current state : DOWN Line protocol current state : DOWN Description:HUAWEI, Quidway Series, GigabitEthernet0/0/1 Interface Switch Port, PVID : 10, TPID : 8100(Hex), The Maximum Frame Length is 2044 IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is 5489-98d0-2114 Port Mode: COMBO AUTO //The port is a combo port and automatically works as an optical or electrical port. Current Work Mode: COPPER //The port is an electrical port. Speed : 10, Loopback: NONE Duplex: HALF, Negotiation: ENABLE Mdi : 3. How does a combo port work? For E series switches: A combo port works in the auto mode by default, and can automatically work as an optical or electrical port. The port can check whether an optical module has been installed. For S series switches: In V100R003 and earlier versions, a combo port works as an optical port by default. In V100R005 and later versions, a combo port works in auto mode by default. In this mode, the port automatically works as an optical or electrical port. The port can check whether an optical module has been installed. When working in auto mode, a combo port works as an optical/electrical port using the following methods: - If the optical port has no optical module installed and the electrical port has no network cable connected, the port type depends on which a port is connected first. If the electrical port is connected by a network cable first, the electrical port is used for data switching. If the optical port has an optical module installed first, the optical port is used for data switching. - If the electrical port has a network cable connected and is in Up state, the electrical port is still used for data switching when the optical port has an optical module installed. - If the optical port has an optical module installed, it is still used for data switching when the electrical port has a network cable connected, regardless of whether the optical port is in Up state. - If the optical port has an optical module installed and the electrical port has a network cable connected, the optical port is used for data switching after the switch restarts. You can run the combo-port { auto | copper | fiber } command in the interface view to manually configure a combo port to work as an optical or electrical port. 4. How can I configure a combo port? You can run the combo-port { auto | copper | fiber } command to configure the working mode of a combo port. By default, a combo port works in auto mode, and automatically works as an optical or electrical port.

How can I view the combo port number on an S series switch
You can use the following methods to identify a combo port on a switch: 1. Identify a combo port based on the port ID on the switch panel. If two ports have the same ID but connects to different transmission media (optical & electrical), the two ports are multiplexed as a combo port. 2. Run the display interface command to display the combo port information. display interface gigabitethernet 1/0/1 ... IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is 0025-9e80-2494 Port Mode: COMBO AUTO Speed : 100, Loopback: NONE
