I have two 6509's. One running CATOS and the other has the new integrated IOS. If I connect a crossover b/t the switches on 10/100 ports, the CATOS switch shows link and says the port is connected. The other switch shows that the port is down/(line protocol down [not connected]). Both ports are not in shutdown state. I see many CRC and runt errors on the Integraded IOS switch on that port but I see no such errors on the CATOS switch. Both ports are set to speed 100 and duplex full. I have swapped cables and have changed ports on both switches to eliminate these from being the problem. Any ideas on what could be causing this would be appreciated.
