I have one cisco 6513 in production with WS-6148-GE-TX modules running on 12.2(17)SXF7 IOS and some HP servers with one GB NIC cards. Both the sides are auto negotiation is confugured but still its not taking 1000 Mb full duplex. It's self taking 100M FD(full duplex)/ 100M HD(half duplex) and the states are changing intermittently.
The IEEE 802.3ab autonegotiation protocol manages the switch settings for speed (10 Mbps, 100 Mbps, and 1000 Mbps, excluding SFP module ports) and duplex (half or full). There are situations when this protocol can incorrectly align these settings, reducing performance (although if set to autonegotiation on both sides it should work properly). To rest your self, configure them manually 1000/Full.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
