Note that item "a" in both sections 28D.5 (Base-T) and 28D.6 (10GBASE-T) indicate that auto-negotiation is mandatory. The rest of the text just gives you so.
Why can't I turn AutoNegotiation off on my Gigabit and 10 Gigabit links
Autonegotiation is a signaling mechanism and procedure used by Ethernet over twisted pair by extended in the gigabit Ethernet standard, and is mandatory for BASE-T gigabit Ethernet over twisted pair. The new standard specified that BASE-T Ethernet at 1 Gbit/s over copper wiring requires autonegotiation. Per the IEEE standard for base-T, autonegotiation is a requirement.
This may happen for example if one is configured for autonegotiation while the other one has a fixed mode of operation that is full duplex no autonegotiation.
The first such word is known as a base link code wordand its bits are used as follows:. They are unipolar positive-only electrical pulses of a nominal duration of ns, with a maximum pulse width of ns,  generated at a 16 ms time interval with a timing variation tolerance of 8 ms.

IEEE ab Meeting. Montreal, Canada. Mark T.
Feuerstraeter, Level One, (), [email protected] While Auto-Negotiation can be disabled on 10BASE-T and BASE-TX links, it is required on BASE-T systems since Gigabit Ethernet systems use.
New technologies such as BASE-T require autonegotiation. The IEEE. a switch, setting the switch ports to autonegotiation enabled is mandatory.
Although most manufacturers implemented this standard in one way, some others, including network giant Ciscoimplemented it in a different way.

Autonegotiation is covered by the US patents U. Post as a guest Name. Instead, only the BASE-X fiber optic media system has an Auto-Negotiation spec that allows the link partners on a Gigabit Ethernet fiber optic link to determine which modes of operation they support in common e. New York: Wiley Computer Pub. Autonegotiation is based on pulses similar to those used by 10BASE-T devices to detect the presence of a connection to another device.
