One of the guys on the Minasi forum, Wes Lazara, posted a link last night to a Dell support article. This article states that:
“NOTE: For configuring NIC team and VLAN, the minimum supported driver version for the Broadcom NIC is 12.6 and for Intel NIC is 11.0. It is recommended that you download the latest drivers from the Dell Support website at support.dell.com.
NOTE: Hyper-V cannot manage tagging when using a teaming software. Instead, the teaming software can be used for VLAN tagging.”
Go to the last section of the diagram to get the support statement.
Thanks to Wes for contacting Dell support and for posting the answer.
