Some Questions about NFA

Some Questions about NFA

Hi All,

       Recently we have a POC about NFA for customer who has OPM v11600 version to monitor network devices.
       Here is the detail info:
       NFA version is v12100, source data  are from Cisco/Huawei. All flow version uses v9 including Netflow and Netstream according to userguide.
       Question 1: Respectively from NFA and OPM, the same interface in/out value is deffierent as attachement.
                         As we known, OPM mainly get the data from SNMP protocol and NFA get the data from flow protocol, but the value is different so much. The reason I thought is related the sampling, so could you mind to help us check it again?
       Question 2: As for 10G interfaces, OPM snapshot will display 10000000000bps and NFA will show 4294967295 Bps, and I tried to use MiBbrowser to poll these interfaces, the speed of these interfaces is 4294967295 bit per second according to the OID description. I don't know if it will affect the value display for client.
