sFlow
Configuring and activating sFlow
Instance configuration settings
Each instance can be customized as follows:
Packet flow sampling
Packet flow sampling is executed by copying a specified amount of data from the header of
packets and sending it to a collector for analysis.
Collector
Select the collector to which data will be sent.
Sampling rate
Specify the approximate number of packets between samples. For example, if set to 5,
approximately every fifth packet will be sampled (There is some jitter introduced
purposefully into the sample collection). A value of 0 disables sampling.
Max header size
Specify the maximum number of bytes to copy and forward from the header of the sampled
packet.
Counter sampling
Counter sampling measurement are obtained by counting the number of packets and octets
passing through the target interface between the defined polling interval.
Collector
Select the collector to which data will be sent.
Polling interval
Specify the amount of time (in seconds) between sending successive octet and packet
counter values for this instance.
