Cat3524 & Broadcom problem

[saebischer]

The Cisco Catalyst switch is configured with auto speed. The broadcom adapter of the DELL D600 has the problem (10 pings, about 90% successful)

with the following configuration:

100FD

100HD

Auto

If we configure the broadcom adapter with the following configuration, we do not have network interrupts anymore (10 pings, 100% successful):

10FD

10HD

Broadcom 570x Gigabit Integrated Controller, Firmware BCM5702 A2/5702-v2.25

OS: W2K Pro SP3, Driver details: b57w2k.sys / v6.34 (06/10/2003)

Does anybody know something about this Problem ?

Hi,

As a test: Set your Cat3524 ethernet port that connects to the Dell from auto to 100 Full Duplex (on the interface, speed 100, duplex full)and configure your Dell to support 100 Full Duplex. Make sure you see the 3524 port as 100 MB full duplex and not auto-100-full-duplex (use the "show interface status" command to verify). Run the ping tests again.

Also make sure you have portfast enabled on the 3524 port that connects to the Dell (or any server/host for that matter).

Other than that, check your drivers etc and check the cisco NIC troubleshooting PDF...

Hi,

We also have the same problem, if the speed of the port change from auto to 10, and half-duplex. The PC will have 100 % ping successful. If the speed and port are auto, the PC will have ping lose. We need replace the unit to solve this problem; it seems hardware fault. Upgrade the IOS of the switch deos not solve this problem.

Hopes it useful for you!

Michael.

Hi Michael

Thanks for you input ! But its very strange, the switches are really the same. Same IOS, same Bootstrap, same HW Revision...everything.

But your Problem was solved after a replace of the unit ?

Kind regards,

Sascha

Hi Rob

Thank you very much for your imput. We have tried this on our switches, but it doesn't work. I think we have to change this switches.

Thank you anyway.

Kind regards,

Sascha

Hi Sascha,

Hope it goes well. If you replace the switch, what are you going to replace with...

The 2950's are good switches (and smaller than the 3524's), with some good QOS options....

Good luck in your endeavours

Regards

Rob

I know this is an old thread, but what are the S/N's on the 3524's that you have this problem with? We had some that were defective and would not work properly with any GigE card.

Did Cisco admit it a bug or it is just failure of hardware? We have a lot of 3524 switches. Some of them are working fine. Some of them failed to connect to sort of fastethernet card at 100. We also noticed that if the activity light on NIC is always on, no good. If it is flashing, good.

Thanks,

Bill.

I too am experiencing this problem with a number 3524 switches - exactly the same symptoms (ping response is only clean when ports are configured to 10Mb/s) and all appear to have the serial number FAB0601xxxx, which gives where and when the switch was manufactured.

see the following url :

http://www.cisco.com/en/US/products/hw/switches/ps607/products_field_notice09186a0080094be8.shtml

for details for working out the date codes.

Not sure if you have similar results!
