duplex

Function

The duplex command configures the duplex mode on an Ethernet electrical interface in non-auto-negotiation mode.

The undo duplex command restores the default duplex mode on an Ethernet electrical interface in no-auto-negotiation mode.

By default, an Ethernet electrical interface works in full-duplex mode when auto-negotiation is disabled on the interface.

Format

duplex { full | half }

undo duplex

Parameters

Parameter

Usage Guidelines

Usage Scenario

The duplex mode of an interface needs to be set in the following scenarios:
  • To enable an interface to send and receive packets at the same time, set the full-duplex mode on the interface.
  • To disable an interface from sending and receiving packets at the same time, set the half-duplex mode on the interface.

Prerequisites

The interface works in non-auto negotiation mode.

Precautions

  • A GE electrical interface that works at 1000 Mbit/s supports only the full-duplex mode. A GE electrical interface and its peer interface do not need to negotiate the duplex mode.

The interfaces on both ends of a link must have the same duplex mode.

Example

# Configure Ethernet electrical interface GE0/0/1 to work in half-duplex mode when non-auto negotiation is disabled on the interface.
