Configuring samplers
A sampler samples packets. The sampler selects a packet from among sequential packets, and it 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 among sequential packets in each sampling.
• Random mode—Any packet might be selected from among sequential packets in each sampling.
The switch supports only the fixed mode.
