Abstract
A method for implementing a link level service in a computer network having a first port device and a second port device coupled by a communication link. Prior to a link incident being reported, the first port device executes a link incident record registration (LIRR) ELS message addressed to the second port device. The second port device responds to the LIRR by adding an address of the first port device to a registration list of ports registered to receive link incident reports. The second port device also responds to the LIRR by sending an accept reply message addressed to the first port device. After a link incident is detected by the second port device, the second port device generates a link incident record comprising data describing the link incident. The second port device selects an address from the registration list sends a registered link incident record ELS message addressed to the selected address.
