How to change statistic sample intervals?

[Wanderley_Benac]

Hi community,

I am collecting port statistics on Summit 48si, but values are set to zero at end of sample interval according to MIB description, see example below:
- OID: 1.3.6.1.4.1.1916.1.11.1.1.4 extremeRtStatsUndersizePkts
- OID Description: The number of packets received during the last sampling interval that were less than 64 octets.

My questions are related to sample interval mention above:
- What is default value of Sample Interval?
- Is there any way to change Sample Interval value?

Thanks in advance for all collaboration,
Wanderley Benacchio Junior

Wanderley, per the extremeRtStatsIndex, the description states "The last sample of Ethernet statistics on a particular Ethernet interface. This sample is associated with the RMON historyControlEntry which set up the parameters for a regular collection of these samples".

Please review the MIB in use for any RMON OIDs and see if there are any options there.
