Ethernet interface configuration

Ethernet interface naming conventions

The GE and 10-GE interfaces on the A5120 EI Switch Series are named in the format of interface-type

A/B/C, where the following definitions apply:

 If the switch does not support Intelligent Resilient Framework (IRF), A takes 1. If the switch supports

IRF, A represents the ID of the switch in an IRF fabric. If the switch is not assigned to any IRF fabric,

A uses 1.

 B represents a slot number on the switch. It uses 0 for fixed interfaces, 1 for interfaces on interface

expansion card 1, and 2 for interfaces on interface expansion card 2.

 C represents the number of an interface on a slot.

NOTE:

 For more information about the expansion cards, see the

HP A5120 EI Switch Series Installation Guide.

 The HP A5120-24G EI Switch(JE066A) and the HP A5120-48G EI Switch(JE067A) do not support IRF.

Configuring basic settings of an Ethernet interface

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 one port, the other is automatically disabled.

The fiber combo port and the copper combo port are Layer 2 Ethernet interfaces. They have their own

separate interface views, 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 a combo interface, complete the following tasks:

 Use the display port combo command to identify the combo interfaces on your device and identify

the two physical ports that compose each combo interface.

 Use the display interface command to determine, of the two physical ports that compose a combo

interface, which is the fiber combo port and which is the cooper combo port. 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 include ―Media type is not sure,

Port hardware type is No connector‖.

Changing the active port of a combo interface

Follow these steps to change the active port of a double combo interface:
