Abstract
The present disclosure discloses a system and method for monitoring link quality between internetworking devices. The system includes a processor and a memory storing instructions that, when executed, cause the system to: generate, at a first internetworking device, a marker-request packet that includes a current marker ID; send, from the first internetworking device, the marker-request packet to a second internetworking device; receive, at the first internetworking device, a marker-reply packet that responds to the marker-request packet from the second internetworking device, the marker-reply packet including the current marker ID and a previous marker ID; and determine, at the first network device, a link quality between the first internetworking device and the second internetworking device based at least in part on the marker-reply packet.
