                "Identifies a source of sFlow data.
 | 
						|
 | 
						|
                The following data source types are currently defined:
 | 
						|
 | 
						|
                - ifIndex.<I>
 | 
						|
                SFlowDataSources of this traditional form are called
 | 
						|
                'port-based'. Ideally the sampling entity will perform 
 | 
						|
                sampling on all flows originating from or destined to 
 | 
						|
                the specified interface. However, if the switch architecture 
 | 
						|
                only allows input or output sampling then the sampling agent 
 | 
						|
                is permitted to only sample input flows input or output flows. 
 | 
						|
                Each packet must only be considered once for sampling, 
 | 
						|
                irrespective of the number of ports it will be forwarded to.
 | 
						|
                Note: Port 0 is used to indicate that all ports on the device
 | 
						|
                      are represented by a single data source.
 | 
						|
                      - sFlowFsPacketSamplingRate applies to all ports on the
 | 
						|
                        device capable of packet sampling.
 | 
						|
 | 
						|
                - smonVlanDataSource.<V>
 | 
						|
                An SFlowDataSource of this form refers to a 'Packet-based VLAN'
 | 
						|
                and is called a 'VLAN-based' dataSource. <V> is the VLAN
 | 
						|
                ID as defined by the IEEE 802.1Q standard. The
 | 
						|
                value is between 1 and 4094 inclusive, and it represents
 | 
						|
                an 802.1Q VLAN-ID with global scope within a given
 | 
						|
                bridged domain.
 | 
						|
                Sampling is performed on all packets received that are part
 | 
						|
                of the specified VLAN (no matter which port they arrived on).
 | 
						|
                Each packet will only be considered once for sampling,
 | 
						|
                irrespective of the number of ports it will be forwarded to.
 | 
						|
                
 | 
						|
                - entPhysicalEntry.<N>
 | 
						|
                An SFlowDataSource of this form refers to a physical entity 
 | 
						|
                within the agent (e.g. entPhysicalClass = backplane(4)) and 
 | 
						|
                is called an 'entity-based' dataSource. Sampling is performed 
 | 
						|
                on all packets entering the resource (e.g. If the backplane 
 | 
						|
                is being sampled, all packets transmitted onto the backplane 
 | 
						|
                will be considered as single candidates for sampling 
 | 
						|
                irrespective of the number of ports they ultimately reach).
 | 
						|
 | 
						|
                Note: Since each SFlowDataSource operates independently a 
 | 
						|
                      packet that crosses multiple DataSources may generate 
 | 
						|
                      multiple flow records."

                 If the value is currently zero it may be set to any

                 When the sampling rate is set the agent is free to adjust the
 | 
						|
                 value so that it lies between the maximum and minimum values
 | 
						|
                 and has the closest achievable value.
 | 
						|
 | 
						|
                 When read, the agent must return the actual sampling interval
 | 
						|
                 it will be using (after the adjustments previously described).
 | 
						|
                 The sampling algorithm must converge so that over time the
 | 
						|
                 number of packets sampled approaches 1/Nth of the total number
 | 
						|
                 of packets in the monitored flows."
