LACP interface status : lag_inactive

Hello All,

We stuck with investigation of one issue related with LACP 
One port is failing to receive successive LACP protocol packets and staying in lag_inactive status.
netapp controller is sending LACP packets but doesn't receiving them from the switch.
Same behavior we can see on network switch(PDUs sent are increasing , however received PDUs are staying in same value).

We tried to reset interface but it didn't help.
our environment
FAS: FAS6210
network card: 10 Gigabit Ethernet Controller IX1-SFP+
ontap version: 8.2.1 7-Mode

switch is running : 

Cisco Nexus Operating System (NX-OS) Software 5.2(7)


here is output from "vif status"
attached lacp_log file
