In some examples, a switching system includes a plurality of fabric endpoints and a multi-stage switching fabric having a plurality of fabric planes each having a plurality of stages to switch data units between any of the plurality of fabric endpoints. A fabric endpoint of the fabric endpoints is configured to send, to a switch of a first one of the stages and within a first fabric plane of the plurality of fabric planes, a self-ping message destined for the fabric endpoint. The fabric endpoint is configured to send, in response to determining the fabric endpoint has not received the self-ping message after a predetermined time, an indication of a connectivity fault for the first fabric plane.
