<p>A method for implementing a link level service in a computer network having a first port device (107) and a second port device (109). Node identification data is stored in the second port device (109). A physical-layer communications coupling is provided between the first port device (107) and the second port device (109) which may be a point-to-point, loop, or switched circuit connection. The first port device (107) sends a request node identification (RNID) message addressed to the second port device (109). The second port device (109) creates an accept message and copies stored node identification data into the accept message. The second port device (109) sends the accept message to the first port device (107).</p> |
