Description: The number of packets pertaining to the protocol identified by natProtocol that had to be rejected/dropped due to lack of resources. These rejections could be due to session timeout, resource unavailability, lack of address space, etc.

Discontinuities in the value of this counter can occur at reinitialization of the management system and at other times, as indicated by the value of ifCounterDiscontinuityTime on the relevant interface. Deprecated in favor of NATV2-MIB.

What is natProtocolDiscards?

A 64-bit counter of packets for this protocol that were dropped due to lack of resources (session timeout, address exhaustion, etc.) device-wide; a rising value here for one protocol points at capacity pressure specific to that traffic type. Deprecated in favor of NATV2-MIB.
