negotiation mismatch??

I instaled a new pair of ptp200, the link is perfect, but when i do a ping test with load (to the local radio) it looses packets…just like when there is ethernet negotiation mismatch betwin radio and cisco switch.
I tryied all posible combination forcing both radio and switch.

Have anyone seen this??

Likely

Try forcing the radio and switch to a single rate - 100fdx or 100hdx
