Configuring a sampler

A sampler samples packets. The sampler selects a packet from among sequential packets, and it sends the packet to the service module for processing.

The following sampling modes are available:

• Fixed mode—The first packet is selected from among several sequential packets in each sampling.

• Random mode—Any packet might be selected from among several sequential packets in each sampling.

A sampler can be used to sample packets for NetStream. Only the sampled packets are sent and processed by the traffic monitoring module. Sampling is useful if you have too much traffic and want to limit how much traffic is analyzed. The sampled data is statistically accurate and decreases the impact on the device's forwarding capacity. For more information about NetStream, see "Configuring NetStream"

	NOTE: The device supports only the fixed mode. The HPE 5820X Switch Series does not support a sampler.
