sflow sample-rate (Interface)
Change the interface default sampling rate.
Syntax
sflow sample-rate value
To return to the default sampling rate, use the no sflow sample-rate command.
Parameters
value Enter the sampling rate value. The range is from 256 to 8388608 packets. Enter
values in powers of 2 only; for example, 4096, 8192, and 16384. The default is the
Global default sampling.
Defaults The Global default sampling.

Usage
Information
This command changes the sampling rate for an interface. By default, the sampling rate of an interface is
set to the same value as the current global default sampling rate. If the value you enter is not a correct
power of 2, the command generates an error message with the previous and next power-of-2 value.
Select one of these two numbers and re-enter the command.
