Just a thought for what it's worth: Has anybody tried using Single-port LAGs with LACP for link keep-alives? We use VLACP (Virtual LACP) between some Nortel switches so that OSPF sees a broken end-to-end link even if there is a device keeping the ports up (link up but no traffic from peer). Examples of such devices are in our case encryption boxes.
But flap-detection would have to monitor LACP as well as physical links and I am not sure if that has been implemented, and I haven't read the manual!
