sFlow

sFlow configuration manages global sFlow sampling and collector settings on NX-OS devices. Settings include agent address, sampling rate, header size, counter polling interval, collector receivers, data source interfaces, and extended flow types (BGP, switch).

Examples

Example 1: Basic sFlow with a single collector

nxos:
  devices:
    - name: LEAF1
      configuration:
        feature:
          sflow: true
        sflow:
          agent_ip: 10.0.0.1
          sampling_rate: 4096
          collector_port: 6343
          collectors:
            - address: 10.92.198.113
              vrf: management

Example 2: sFlow with multiple collectors and tuned parameters

nxos:
  devices:
    - name: LEAF1
      configuration:
        feature:
          sflow: true
