Configures the sFlow default sampling rate.
| number | Specifies the fraction (1/number) of packets to be sampled. |
The default number is 8192.
This command configures the default sampling rate. This is the rate that newly enabled sFlow ports will have their sample rate set to. Changing this rate will not affect currently enabled sFlow ports. The rate is rounded off to the next power of two, so if 400 is specified, the sample rate is configured as 512. The valid range is 256 to 536870912.
Configuring a lower number for the sample rate means that more samples will be taken, increasing the load on the switch. Do not configure the sample rate to a number lower than the default unless you are sure that the traffic rate on the source is low.
The minimum rate that these platforms sample is 1 out of every 256 packets. If you configure a rate to be less than 256, the switch automatically rounds up the sample rate to 256.
The following example sets the sample rate to one packet out of every 16384:
configure sflow sample-rate 16384
