bl460g7 teaming issue

[杏仁]

bl460g7 embedded nic 553i teaming ：nft  mode

After  I set teaming,1 mintue or more nic1 will auto switch to nic2, If I switch nic1 to active nic by manual mode,but nic1 will auto switch to nic2 after a while 。

hp support tell me to upgrade nic driver(4.0360.8) and ncu(10.45.00) and nic firmware (4.0460.15a)to latest ,but iisue still exist .

Network environment：

os:win2008r2 server ent.

switch： hp 6120xg *2 use port 17  connect to uplink

storage：hp p4300g2*2 10gb connect to 6120xg 18 and 19port 

server：hp bl460g7 *5

server （port 1-5）and storage（18-19） and port 17 on vlan 2

all servers and storages port on vlan2 are untagged，but   port 17    is tagged。

ufd function is enable。

only two servers have issue of teaming,and p4300g3 have assigned a volume to fault servers。

what can i do?

thanks
