This read-only counter tracks the number of failures detected by the CLNP reassembly algorithm, for any reason including a timeout being reached or insufficient buffer space. An admin watching this counter rise would suspect either the clnpReasmTimeout value is too short for the network's actual latency or that buffer resources for reassembly are undersized. For example, a rising failure count that correlates with network congestion, rather than with the specific reassembly timeout, would point the admin toward a buffer-capacity problem instead of a timing issue.
