Usage
Use this command to set sFlow packet sampling rate. The rate value is packet number. When
the value is 32768, one packet will be sampled when 32768 packets are passed, sFlow uses
CPU resources to collect samples and send samples to the collector. If a low sampling rate is
set, CPU utilization can become high. To protect CPU from overwhelming, exceeded flow
samples would be dropped. If a sampling rate less than default value is configured, a prompt
will be given to info the potential of involving a high CPU utilization. This command can only
be configured on a port which is not a link-agg group member. The port can be either a
physical port or a link-agg port.
