rttMonStatisticsAdminNumHops
Round Trip Time Monitor Statistics Admin Num Hops
1.3.6.1.4.1.9.9.42.1.2.7.1.3
When RttMonRttType is 'pathEcho' this is the maximum number of statistics hops to record per path group. This value directly represents the number of hops along a path to a target, thus we can only support 30 hops. For all other RttMonRttTypes this value will be forced to one by the agent. Since this index does not rollover, only the first rttMonStatisticsAdminNumHops will be kept. This object is applicable to pathEcho probes only.
