Configuring the Capability to Detect Corruption in the FPGA Statistics for Policies Managed by the SRC Software

To configure the capability to check for corruption in the FPGA statistics for policies managed by the SRC server:

1. Enable the detection functionality to identify inaccuracies in the FPGA statistics before the counter values are reported to the SRC server during a COPS session.

   host#fpga-stats-monitoring-enable

   By default, the functionality to detect corruption in the FPGA statistics is disabled. Use the no version of this command to disable this functionality.

2. Specify a threshold value that is used as a checkpoint to determine whether the FPGA statistics is corrupted. The threshold is the maximum permissible deviation between interface and policy counter values. If the threshold is higher than the difference between the interface and policy counters, no corruption has occurred in the FPGA statistics. If the threshold is lower than the difference between the interface and policy counters, corruption has occurred in the FPGA statistics.

   host1(config)# fpga-stats-monitoring threshold 40 

   In this example, the threshold value is set as 40. If the difference between the interface counters and policy counters for ingress or egress policies collected over two polling intervals equals or exceeds 40, a corruption is detected in the FPGA statistics and the subscriber statistics are not forwarded to the SRC server. If the difference between the interface counters and policy counters for ingress or egress policies collected over two polling intervals is less than 40, no corruption is identified in the FPGA statistics and the collected subscriber statistical details are sent to the SRC server.
