Configuring a combo interface
A combo interface is a logical interface that physically comprises one fiber combo port and one copper combo port. The two ports share one forwarding channel and one interface view. As a result, they cannot work simultaneously. When you activate one port, the other port is automatically disabled. In the interface view, you can activate the fiber or copper combo port, and configure other port attributes such as the interface rate and duplex mode.
Configuration prerequisites
Before you configure combo interfaces, complete the following tasks:
Determine the combo interfaces on your device. Identify the two physical interfaces that belong to each combo interface according to the marks on the device panel.
Use the display interface command to determine which port (fiber or copper) of each combo interface is active:
If the copper port is active, the output includes "Media type is twisted pair."
If the fiber port is active, the output does not include this information.
Also, you can use the display this command in the view of each combo interface to display the combo interface configuration:
If the fiber port is active, the combo enable fiber command exists in the output.
If the copper port is active, the combo enable fiber command does not exist in the output.
Changing the active port of a combo interface
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter Ethernet interface view. | interface interface-type interface-number | N/A |
3. Activate the copper combo port or fiber combo port. | combo enable { copper | fiber } | By default, the copper combo port is active. |
