Answer
- Yes,both UDP and TCP traffic contributes to the 100,000 connection limit per node.
- Connection ID (CID) limit is 100K
- UDP is considered stateless, but ONTAPholds an internal "connection-id" open for 2 minutes in case another call comes in on the same ip/port combination
- UDP CIDshave a lifecycle of at least 4 seconds, but no more than 60 seconds, if idle
- When 95% of 100Kconnection limit is breached, ONTAP begins deleting the Least Recently Used (LRU) UDP CID
- If new connections outpace the deletion rate, new UDP and TCP connections may see intermittent un-responsiveness
