This value is included in a trap indicating that an FCoE port resource has reached its maximum configured limit. An admin receiving this trap object uses it to identify which specific resource threshold was hit, prompting a check of port capacity such as the number of virtual FCoE ports it can support. For example, a trap carrying hwFCoEPortResource would alert an admin that a device has reached its maximum FCoE port resource allocation, signaling no further FCoE sessions can be established on that port until resources free up.
