Removed from the article

Note that some switch operating systems, as well as some card drivers, still have the option to disable autonegotiation and force a twisted pair connection to 1000Base-T full duplex or 1000Base-T half duplex, but this is against specification and should never be used because this way the other parameters required for Gigabit Ethernet operation are not negotiated. The correct way for forcing Gigabit Ethernet operation is to enable autonegotiation, but limit the advertised capabilities to the 1000Base-T ones only[1].

A doubt was raised about "still have the option to disable autonegotiation" at Talk:Ethernet. Source should be provided. (Liberatore, 2006). 12:19, 29 June 2006 (UTC)[reply]

Well this is a way old discussion and I'm not going to add the section back, but here's a quote from a Sun document showing they did offer hardware with this capability (1000 Full-forced, Autoneg-disabled), "The IEEE 802.3ab specification does not allow for forced mode 1000BASE-T with autonegotiation disabled running at 1000 Mbps. As a result, many switch vendors do not support forced mode. Although the transceiver used in the Sun™ Gigaswift Ethernet UTP adapter 1.0 is configurable for the 1000 Mbps forced mode and the ce driver allows this mode be aware that it does not work under certain circumstances."

Good article

I guess this article might qualify as a good article, and I intend to nominate it at Wikipedia:Good article candidates (Liberatore, 2006). 12:32, 9 August 2006 (UTC)[reply]
