2012 switch-independent teaming causing mac flap (cisco)

-

hi all,

i've windows 2012 hyper-v server 4 nics plugged in 2 cisco switches (2930g , 3560g) nic team configured in switch-independent , address hash mode.

all seems work well, i've noticed frequent mac flapping notification on both switches. i've tried send icmp echoes hv server , during long time period few echoes got lost, suppose works...

but mac flapping worries me - normal "by-product", or should search problems net?

regards!

regards,
