Symptoms
Observation
Two QL41262 ports are added to a windows SET Switch.
Traffic flows towards to the Qlogic teamed port connected to that SET Switch.
The SET Switch sees many dropped packets in performance counters.
Both two Qlogic teamed adapters (part of that SET switch).
Hyper-V Virtual Switch counters shows "dropped Packets Incoming/sec" similar to Packets Received or Sent.
"Hyper-V Virtual network adapter" performance counters show exactly the same number of dropped packets but for outgoing. vSwitch was showing for incoming traffic.
Impact and Resolution
This is a cosmetic issue. It does not impact performance or cluster functionality.
Do not enable SRIOV to work around it.
SRIOV is not validated with Dell Solutions for Microsoft Azure Stack HCI.
Support for deployments with SR-IOV is on a best-effort basis.
