Hi All,
Has anyone had any problems connecting servers or PCs that use a Broadcom
570x 10/100/1000 Gigabit NIC to any of the Catalyst 2900, 4500, 6500 series? For some time we have been experiencing speed and/or duplex problems when connecting the above NICs to any of the above switches. We hard-code the speed and duplex on both ends, yet the problem still exists. In some cases, if you set one side or the other to "auto/auto" then you get whatever speed and duplex the other side is set to. Sometime this works, sometimes it doesn't. This problem is not specific to one type of port on the Catalyst. It affects both the FastE and the GigE ports.To answer the obvious questions, yes we have tried different NICs, and different patch cables, and even entirely different cable runs. We have tried multiple ports on multiple switches to no avail. To only thing that we are running that might be considered "non-standard" is spanning-tree portfast on the ports. I don't recall if we have tried running a test without this, but I don't think that it would cause the symptoms that we are seeing. Other NIC brands (Intel, 3Com, etc) are not effected.
Any ideas? All thoughts are appreciated!!!
Regards,
Richard Graves
