+=== Link Aggregation Silent Failure
+==== Description
+Verify communication over a link aggregate in static and LACP mode when
+member links stop passing traffic without any carrier loss.  In static
+mode the ARP monitor is used in both ends of the lag, in LACP mode this
+is not necessary, and must in fact be disabled.
+
+.Logical network setup, link breakers (lb1 & lb2) here managed by host PC

+The host verifies connectivity with dut2 via dut1 over the aggregate for

+. Set up topology and attach to target DUTs
+. Set up static link aggregate, lag0, on dut1 and dut2
+. Verify failure modes for static mode
+. Set up LACP link aggregate, lag0, on dut1 and dut2
