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.
