rttMonCtrlAdminVerifyData
Round Trip Time Monitor Control Admin Verify Data
1.3.6.1.4.1.9.9.42.1.2.1.1.8
When set to true, the resulting data in each RTT operation is compared with the expected data. This includes checking header information (if possible) and exact packet size. Any mismatch will be recorded in the rttMonStatsCollectVerifyErrors object. Some RttMonRttTypes may not support this option. When a type does not support this option, the agent will transition this object to false. It is the management applications responsibility to check for this transition. This object is only applicable to SNA protocols.
