=== Ling Aggregation Basic ifdef::topdoc[:imagesdir: {topdoc}../../test/case/interfaces/lag_basic] ==== Description Verify communication over a link aggregate in static and LACP operating modes during basic failure scenarios. .Internal network setup, PC verifies connectivity with dut2 via dut1 image::lag-basic.svg[align=center, scaledwidth=75%] The host verifies connectivity with dut2 via dut1 over the aggregate for each test step using the `mon` interface. ==== Topology image::topology.svg[Ling Aggregation Basic topology, align=center, scaledwidth=75%] ==== Sequence . Set up topology and attach to target DUTs . Set up LACP link aggregate, lag0, on dut1 and dut2 . Verify failure modes for lacp mode . Set up static link aggregate, lag0, on dut1 and dut2 . Verify failure modes for static mode
