This reports the fault status signaled by the remote peer PE for this pseudowire, typically received via the LDP status TLV mechanism, telling this router that a problem exists on the far end's attachment circuit or forwarding path rather than locally. This is what lets an admin at one site diagnose a problem physically located at the remote site without needing direct access to that remote device, since the fault information is relayed automatically through the pseudowire signaling. A remote fault present while the local fault is clear tells the admin the customer-facing issue is actually at the far-end site, redirecting the investigation there instead of locally.
