Hi all,
I have a connection problem between a 3750 IOS 12.2 and a 3550 IOS 12.1. I'm using a straight cable and configured MDIX on 3750 end, setting speed to 'auto' as indicated by documentation. There's no way of making it working. Do you know any issue related to MDIX on the interconnection of different switches?
Do I need same IOS train release on both?
Thanks
Chiara
