3550 and speed 10

Hello,

I have a link between 3550 (12.1(19)EA1a) and a Operator's switch C2924M-XL (12.0(5.2)XU) .

Before the speed between the 2 switchs was 100M/Full but we have modify in 10M/full. But now we have some errors and crc on the 3550's interface and not on 2924's interface.

Could you help me to resolve this problem.

Thanks

Best regards

Hi,

When connecting 2 Cisco interfaces togather you should consider to leave it on auto speed and auto duplex. But if you want to fix the speed/duplex then you must do on both ends.

I have also noticed your IOS on both switches are very old, consider an IOS upgrade. To download the IOS from Cisco.com you will need a CCO account or you may need to speak to your Hardware supplier/Cisco partner.

HTH
