I have two clustered nodes. Failover Clustering is working fine in SQL Server.
But the problem is in initiating the communication. When I connected any device in the LAN and starts sending packets, the packets are not going anywhere(Nothing can be captured in wireshark) but as I do failover (by removing LAN or by any means), packets starts coming(Captured in wireshark).



So, I think the problem is of IP-MAC Conflict. When failover happens node send G-ARP to all the devices, so that devices got to know that now Cluster IP is associated to this MAC address. But how to resolve this IP-MAC conflict initially because if I don't do failover no packets received and just after doing failover packets starts coming on the current primary node of SQL Server Availability Group.
