Re: 3750----FLAPPING betwwen ports

Hi,

can you check whether any unidirectional link exist in your network. it a host mac address learnt through both the links. Also check is there any active standby switchover happening as well. I guess these should guide you to some hint of the resolution. Please correct me if i am wrong.

Thanks and Regards,
