Configuring samplers
A sampler selects a packet from sequential packets and sends the packet to other service modules for processing. Sampling is useful when you want to limit the volume of traffic to be analyzed. The sampled data is statistically accurate and sampling decreases the impact on the forwarding capacity of the device.
The following sampling modes are available:
· Fixed mode—The first packet is selected from sequential packets in each sampling.
· Random mode—Any packet might be selected from sequential packets in each sampling. This sampling mode is not supported in the current software version.
