Hello everyone. I have an issue with my Nexus 9k. After server connected to pair of N9K is reloaded, traffic in one of LACP port-channel link doesn't flow. As a result of this partly looses traffic. On Nexus and server ports are up. No error messages are shown. After shut/no shut on Nexus2 traffic is restored.
N9396PX, NXOS: version 7.0(3)I5(1) This situation was on earlier version too.
Windows Server 2012 R2 Std
Help me please.
