Configuring common Ethernet interface settings
This section describes the settings common to Layer 2 and Layer 3 Ethernet interfaces. You can set an
Ethernet interface as a Layer 3 interface by using the port link-mode route command. For more
information, see "
Configuring the link mode of an Ethernet interface
." For more information about the
settings specific to Layer 2 and Layer 3 Ethernet interfaces, see "

Configuring a Layer 3 Ethernet interface
Configuring a combo interface (only applicable to
S5560-30F-EI switches)
A combo interface is a logical interface that physically contains 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.
For more information about the number of combo interfaces, see the installation guide.
Configuration prerequisites
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.
