Known Affected Releases
Symptom: On a nexus 3500 NAT data plane traffic is process switched in software. This traffic will be subjected to copp and may be dropped due to the copp-s-ip-nat CoPP class. Conditions: Dynamic NAT is configured on a nexus 3500. The traffic being punted all matches the configured inside dynamic NAT range. This issue is only seen when traffic flows from a nat inside interface to another nat inside interface. This issue is not seen when traffic flows between a nat inside and nat outside interface. This issue can also happen when traffic flows from a nat inside to an interface that is not configured with NAT.
