We have attempted to implement NIC teaming on our server that has 4 total NICs. There are 2 connections to each switch. I have a diagram to help explain: Server NIC Layout
When we attempt to create a team with all four NICs, we have connection issues and constantly drop RDP sessions. Right now we have a team of two NICs, that connect to each switch. This provide redundancy but I would like to provide some bandwidth aggregation as well. The switches are a Cisco SG300-28 and a Cisco Catalyst 2960. We have tried the 4 NIC team in switch independent mode. Is there a way to get all four NICs into a stable team?
