Configuring NetStream Sampling

Configuring NetStream Sampling

Context

You can set the intervals for sampling packets so that only statistics of sampled packets are collected. The statistics show the flow status on the entire network. The sampling function reduces the impact of NetStream on device performance.

When there is little traffic on the network, you can configure suppression ratio to control flow sampling, instead of sampling.

Procedure

  1. Run the system-view command to enter the system view.
  2. Run the interface interface-type interface-number command to enter the interface view.
  3. (Optional) Run the ip netstream suppress suppress-rate { inbound | outbound } command to set the suppression ratio.

    By default, the suppression ratio on an interface is 1000.

    NOTE:

    Only E series cards (except ET1D2X48SEC0 card) support this command.

  4. Run the ipv6 netstream sampler fix-packets packet-interval { inbound | outbound } command to configure IPv6 packet sampling on the interface.

    By default, the packet-based regular sampling is used. The default packet sampling rate is 1000.
