Activating the copper port or fiber port of a combo interface

Introduction

The following information uses an example to describe the basic procedure for activating the copper port or fiber port of a combo interface.

Network configuration

Activate the copper port or fiber port of a combo interface at the CLI.

Restrictions and guidelines

A combo interface is a logical interface that physically comprises one fiber combo port and one copper combo port on the device panel. The two ports share one forwarding interface and one interface view. As a result, they cannot work simultaneously. When you activate one port, the other port is automatically disabled.

Procedure

# Activate the copper combo port of GigabitEthernet 1/0/1, and connect a twisted pair cable to the interface.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] combo enable copper

[Sysname-GigabitEthernet1/0/1] quit

# Activate the fiber combo port of GigabitEthernet 1/0/1, and connect a fiber to the interface.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] combo enable fiber

[Sysname-GigabitEthernet1/0/1] quit

Verifying the configuration

# When a combo interface is connected to a cable or transceiver module, use the display interface command to view information about the interface. If Media type is twisted pair is displayed in the command output, the copper port is activated. If not, the fiber port is activated.
