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)
