Configuring Ethernet interfaces

Ethernet interface naming conventions

The Ethernet interfaces on the HPE 3100 v2 EI are named in the format of interface-type A/B/C,
where the following definitions apply:
•
A—Specifies the ID of a switch. The value can only be 1.
•
B—Represents a slot number on the switch. It uses 0.
•
C—Represents the number of an interface on a slot.

Configuring a combo interface

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:
•
For the number of combo interfaces that an HPE 3100 v2 switch provides, see the installation
guide.
•
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.
