Flow Sampler Map

Configure flow sampler maps for traffic monitoring and NetFlow sampling on IOS-XR devices. Flow sampler maps define sampling rates and methods for capturing and analyzing network traffic patterns. This feature enables network monitoring, traffic analysis, and performance optimization.

Sample Configuration:

The following configuration describes how to set up flow sampler maps on a Cisco IOS-XR device.

sampler-map sampler_map1
 random 1 out-of 1

Example YAML Code:

Example-1: Basic flow sampler map configuration

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        flow_sampler_maps:
          - name: "sampler_map1"
            random: 1
            out_of: 1000

Example-2: Multiple flow sampler maps with different sampling rates

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        flow_sampler_maps:
          - name: "high_rate_sampler"
            random: 1
            out_of: 100
          - name: "medium_rate_sampler"
            random: 1
            out_of: 1000
          - name: "low_rate_sampler"
            random: 1
            out_of: 10000

Example-3: Flow sampler map with maximum sampling interval

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        flow_sampler_maps:
          - name: "minimal_sampling"
            random: 1
            out_of: 262144

Example-4: Simple flow sampler map for testing

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        flow_sampler_maps:
          - name: "test_sampler"
            random: 1
            out_of: 1

Use Cases:
