Description: The cumulative number of packets dropped rather than translated because the packet would have triggered the creation of a new port map entry, but the limit on number of port map entries for the NAT instance given by natv2InstanceLimitPortMapEntries has already been reached.

This value MUST be monotone increasing in the periods between updates of the entity's natv2InstanceDiscontinuityTime. If a manager detects a change in the latter since the last time it sampled this counter, it SHOULD NOT make use of the difference between the latest value of the counter and any value retrieved before the new value of natv2InstanceDiscontinuityTime.
