Re: 4503 switch

It seems autonegotiation is failing between these 2 switches.

Can you post the exact port config from both switches ?

Thanks

Re: 4503 switch

Hi,

Maybe you have hard-coded the speed/duplex settings on the port in 3560. Just check the settings on the port on 3560. Make speed/duplex auto in 3560 and it should work fine. Or else why not hard-code the speed and duplex settings on ports on both the switch?? That should help!

Regards,

AbhisheK
