When I set Speed and Duplex to auto, the port status is UP (connects at 100/half). Any other combo (100/auto or auto/Full, etc) results in the port to be down.
Here is the sho int:
FastEthernet0/18 is up, line protocol is up (connected)
Hardware is Fast Ethernet, address is 0014.1cd8.0394 (bia 0014.1cd8.0394)
