I have 2 4507's with dual sup IV's and 5 WS-X4448-GB-RJ45 blades.
I can't seem to be able to link the two switches together with a full duplex copper port at any speed. I can link at 10mbit/half and 100mbit/half. If I try and set the both ends to 100/full or even 10/full the interfaces will never come up. They also won't link with both ends set to auto?
Any idea's? I have never had such a problem before. The cable distance is 268 feet and is cat 6. It consists of a couple of patch cables and some cross connects. Could it be a distance issue?
I can indeed establish a 100mbit full duplex with my laptop using the same cable runs. The only difference is I substitue a 5 foot patch cable with one that is not crossed. One thing to note is that only 2 pairs are cross-connected. Are the line cards wanting to use 4 pair even for 100mbit full duplex between the two switches?
