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.
Usage Guidelines
Usage Scenario
- 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
- For details about the duplex modes that various Ethernet interfaces support, see see Overview of Ethernet Interfaces in the Configuration Guide-Overview of Ethernet Interfaces.
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.
