Description: This object affects the way the RMON probe uses statistical sampling to collect packets from the indicated interface.

If this object has the value 'false', then the probe will attempt to monitor all packets detected on the indicated interface, in the event any RMON collections are actually configured. The data returned in all RMON collection tables associated with this interface will represent non-sampled monitored counter values.

If this object has the value 'true', then the probe will use adaptive statistical sampling techniques to monitor the indicated interface, in the event any RMON collections are actually configured. The data returned in RMON collection tables associated with this interface may be based on statistical approximations. In this mode, the RMON agent will also maintain additional MIB objects to provide the confidence interval information for each sampled counter. These objects can be found in the CISCO-RMON-SAMPLING-MIB.

When this object transitions from 'false' to 'true', all active packet capture functions will be suspended, without affecting the contents of any associated filterEntry, filter2Entry, channelEntry, channel2Entry, bufferControlEntry, captureBufferEntry, or captureBufferHighCapacityEntry. Only the low-level packet capture processing is deactivated.

When this object transitions from 'true' to 'false', all suspended packet capture functions associated with the interface will be reactivated.

Note that an NMS application which is unaware of this MIB object will not be able to detect suspended packet capture operations or sampled collections, however multi-manager mis-configuration issues are beyond the scope of this MIB. The packet capture function Get and Set operations are not affected by this object.

If an interface cannot be sampled, or the sampling configuration cannot be modified, then such an instance of this object will be implemented with read-only access.
