Description: This count gives the number of reassembly timer expirations.
What is nncAAL5ReassemblyTimerExpirations?
This counter gives the number of times the AAL5 reassembly timer expired before a complete PDU could be reassembled from its constituent cells. It flags incomplete cell streams, typically caused by lost or misordered ATM cells arriving too slowly or not at all. An admin seeing this counter increase alongside packet loss elsewhere on the path would suspect cell loss on the ATM transport is preventing full PDU reassembly.
