I have two cisco nexus 3064PQ running in vPC domain for multi-chassis LAg, these switches connected to my HP6120XG (c7000 blade center), life was good last 1 week everything was working fine but today i have noticed vpc is down so when i started looking i noticed following.
LACP lost all partners and i am seeing FCS RX error, this is not in production yet so there is almost zero traffic but where this drops coming also i am seeing same behavior on both HP6120xG switch in c7000, how can both switch go bad same time?
Duplex are auto and i have many other blades running with same config and they all are happy.
