Per the IEEE 802.3z specification, if one side of a connection is configured to auto-negotiate, the other side also must be set to auto-negotiate if the connection is to come up. In other words, if a switch is port is configured to auto-negotiate and its attached end node is configured for 1000 Mbps/full-duplex, the 803.2z spec requires that the switch NOT allow the link to come up.
