HP 7000 dl Router manual Full-duplex, Config#interface ethernet 0/1

SROS Command Line Interface Reference Guide Ethernet Interface Configuration Command Set

full-duplex

Use the full-duplexcommand to configure the Ethernet interface for full-duplex operation. This allows the interface to send and receive simultaneously. Use the no form of this to return to the default half-duplexoperation.

Syntax Description

No subcommands.

Default Values

By default, all Ethernet interfaces are configured for half-duplex operation.

Command Modes

Ethernet Interface Configuration Modes

Functional Notes

Full-duplex Ethernet is a variety of Ethernet technology currently being standardized by the IEEE. Because there is no official standard, vendors are free to implement their independent versions of full-duplex operation. Therefore, it is not safe to assume that one vendor’s equipment will work with another.

Devices at each end of a full-duplex link have the ability to send and receive data simultaneously over the link. Theoretically, this simultaneous action can provide twice the bandwidth of normal (half-duplex) Ethernet. To deploy full-duplex Ethernet, each end of the link must only connect to a single device (a workstation or a switched hub port). With only two devices on a full-duplex link, there is no need to use the medium access control mechanism (to share the signal channel with multiple stations) and listen for other transmissions or collisions before sending data.

Note	If the speed is manually set to 10 or 100, the duplex must be manually configured as
	full-duplexor half-duplex. See speed [10 100 auto] on page 484 for more information.

The 10BaseT, 100BaseTX, and 100BaseFX signalling systems support full-duplex operation (because they have transmit and receive signal paths that can be simultaneously active).

Usage Examples

The following example configures the Ethernet interface for full-duplexoperation:

(config)#interface ethernet 0/1

(config-eth 0/1)#full-duplex
