message-rate-limit (Flow Monitoring Logs for NAT)


Hierarchy Level


Define the maximum number of logs or template records in flow monitoring format to be generated for NAT error events per second from the specified interface. These records for NAT error events are generated when addresses for allocation from the NAT pool are not available, when ports for allocation to a subscriber are not available, or when the allocated quota is exceeded for NAT events (more than the configured number of ports is requested).


The message-rate-limit option can be configured only for multiservices interfaces (ms-x/x/x) and not with other interface types.



—Maximum number of flow monitoring log messages per second for NAT error events that can be formatted and sent from the PIC to an external collector. The default rate is 10,000 for an external collector.
