Configuring a combo interface
Introduction to combo interfaces
A combo interface is a logical interface that comprises one optical (fiber) port and one electrical (copper)
port. The two ports share one forwarding interface, so they cannot work simultaneously. When you
enable either port, the other port is automatically disabled.
The fiber combo port and the copper combo port share one interface view, in which 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:
• The following LPUs of the S10500 Switch Series provide combo interfaces: LSU1GP24TXEA,
LSU1GP24TXEB, LSU1GP24TXSE, and LSU1GP24TSE. Each LPU has eight combo interfaces,
numbered 17 through 24. The copper and fiber combo ports of a combo interface share the same
number.
• Use the display interface command to determine which port (fiber or copper) of the combo
interface is active. If the current port is the copper port, the output will include “Media type is
twisted pair, Port hardware type is 1000_BASE_T”. If the current port is the fiber port, the output will
not include the information mentioned above. You can also use the display this command in the
view of the combo interface to view the combo interface configuration. If the combo enable fiber
command exists, the fiber port is active; if the command does not exist, the copper fiber is active.
Changing the active port of a combo interface
Follow these steps to change the active port of a combo interface:
