We have a HyperV cluster setup running on Server 2012 R2 boxes. The servers are connected with 10Gb/s Intel 82599 NICs. The connection is broken into 5 separate virtual adapters (Mgmt, Cluster, ISCSI, LM, VM) with bandwidth limits set using the powershell add/set-vmnetworkadapter. The servers are hosted by a 3rd party at their data center, so the subnets used on the additional vNICs have different VLAN IDs, which has been configured with set-vmnetworkadaptervlan. This setup has been working, and guest VMs can use the correct subnets as long as the VLAN is configured.
The issue is the host does not appear to be properly using the VLAN tag any any adapter that requires it. The only adapter the host can use is the management adapter that is untagged. Is there some other area I need to configure for the host to use the other adapters that require a VLAN tag?
