Basic Cflowd Configuration
This section provides information to configure cflowd and configuration examples of
common configuration tasks. In order to sample traffic, the minimal cflowd parameters that
need to be configured are:
• Cflowd must be enabled.
• At least one collector must be configured and enabled.
• Sampling must be enabled on either:
→ An IP filter entry and applied to a service or an port.
→ An interface applied to a port.
The following example displays a cflowd configuration.
