Regarding multichannel I have a question. We have several Hyper-V clusters on all of them im trying to restrict SMB Multichannel for CSV traffic. First I configured CSV network with lowest cluster network metric. After I configured SMB constraints but CSV traffic was going thru fe80:: IPv6 address pointed as Server Name which was found with Get-SmbMultichannelConnection. We found that it is the Microsoft cluster virtual adapter. For the rest SMB traffic the constraints work perfectly but not for the CSV. Disabling SMB multichannel for client and server still does not restrict traffic to pass only the lowest metric adapter.
My question is if it is still possible to restrict CSV traffic to pass only specific adapters and how to restrict it?
Hi Jose. You write that "Cluster networking won’t use more than one NIC per subnet" - is this even if we team our NICs in a way that should allow for the use of multiple NICs?
