BIG-IP Virtual Edition (VE) running on a Hyper-V host, when TMM starts, it sets the NIC queue count. When this happens, due to a bug in Hyper-V, ingress packets are no longer received on the data plane interfaces. Packets egressed from TMM are being correctly sent to peer devices on the network.
The data plane interfaces does not show ingress counters incrementing and no traffic is seen on the interface.
- After upgrading from BIG-IP version 12, none of the data plane interfaces show ingress counters incrementing and no traffic is seen on the interface. The Management interface works properly.
In Hyper-V manager, save the machine state and then start it back up or use a legacy network adapter.
