I have a set up where I have two server 2012 hyper-v servers. One is used as primary host, the other as failover.
Veeam is set up to replicate the servers on the first one onto the second. Various jobs with various frequencies depending on requirements.
Failover and failback tests indicate all of this works ok.
However on the failover server I get a Hyper-V-VmSwitch error - event id 95 (The VLAN configuration being set on port 4762DBF3-67D0-44B7-8251-483D54471086 (Friendly Name: Virtual Machines_External) on switch CA089C91-F23D-4924-B7FD-A31FECD77829 (Friendly Name: Virtual Machines) is invalid. Reason: VLAN settings other than Access VLAN Id must be zero)
every single time replication begins.
I cant find any hints anywhere about this error(eventid.net, google, TechNet, here) but as we run a continual replication for one particular server, the event log is just filling up with it.
Ive tried removing the relevant switch from hyper v and recreating it precisely as it is on the primary host server. And checked all settings to see if they look the same both on the switch and the network section on the hyper v console for the servers in question. All without any success.
Any help or suggestions would be gratefully received!
