Cisco is likely to say that the control plane is only fully supported on the management port. After all, the control plane was invented to separate management functions from the data forwarding process.
Cisco will 100% fully support control-plane on in-line ports, before cloudy shop in-line was the norm, MGMT port exception. Management ports to this day are extremely dangerous and I consider using them anti pattern. If you have MGMT L2 broadcast domain, you can potentially break every control-plane by having L2 storms (actual risk that has happened). Because you cannot protect the control-plane on MGMT ETH port, for obvious reasons. And you can protect (some platforms better, some worse) control-plane on in-line ports by combination of QoS, ACL, control-plane ACL, control-plane police/shape/ACL. It might be easier to contribute, if there is familiarity to the subject matter. -- ++ytti
