Help required on 3508 and gigabit copper Please.

I’m running a cisco WS-C3508G-XL-EN with software 12.0(5.4)WC(1) and 4 WS-G5482 1000Base-T GBIC’s connected to and 1 Intel Pro 1000-T (Driver version 2.84.284.0) network Card and 3 3Com 3c996-T Gigabit Copper Cards (Driver Version 1.29).

All the PC’s are running Windows 2000 pro or server.

The built in diag software that comes with the drivers reports that it’s connected at gigabit speed and there are no dropped or bad packets.

The ports are configured for auto negotiation, full duplex and asymmetric flow control.

But if I connect to the console port on the back of the 3508 it reports “2d23b: %LINK-3-UPDOWN: Interface GigabitEthernet0/1, Changed state to up”.

It then changes state to down, this happens for all connected ports.

As a result the throughput on the gigabit ports is less than on a 100 port.

Can anyone give me any idea what I can do to keep the ports up?

Thanks

Jim

Can you clarify if all of the stated ports are showing inconsistent connectivity?

I'm not sure, how do I check?

The console reports the link going up and down.

If I unplug the cable it reports protocol down.
