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 and thus cannot work simultaneously. When
you enable the electrical port, the optical port is disabled automatically and vice versa.
The optical and electrical ports of a Combo interface share one interface view, in which you can activate
the optical or electrical port, and configure other port attributes, such as the interface rate and duplex
mode.
Configuration prerequisites
• Find out the Combo interfaces on your device by checking the product specifications and identify
the two physical interfaces that comprise each Combo interface.
• Use the display interface command to find out which port (optical or electrical) of the current
Combo interface is currently active. If the output includes “Media type is twisted pair, Port hardware
type is 1000_BASE_T”, the electrical port is active; if the output includes “Media type is not sure,
Port hardware type is No connector”, the optical port is active.
Changing the active port of a Combo interface

Configuring an Ethernet interface
You can set an Ethernet interface to operate in one of the following duplex modes:
• Full-duplex mode (full). Interfaces operating in this mode can send and receive packets
simultaneously.
• Half-duplex mode (half). Interfaces operating in this mode cannot send and receive simultaneously.
• Auto-negotiation mode (auto). Interfaces operating in this mode negotiate a duplex mode with their
peers.
Similarly, you can set the speed of an Ethernet interface or enable it to automatically negotiate a speed
with its peer. For a 100-Mbps or 1000-Mbps Layer 2 Ethernet interface, you can also set speed options
for auto negotiation. The two ends can pick a speed only from the available options.
