policy cflowd-template—Create a template that defines the location of cflowd collectors, how often sets of sampled flows should be sent to the collectors, and how often the cflowd template should be sent to the collectors (on vSmart controllers only). You can configure a maximum of four cflowd collectors per vEdge router. To have a template take effect, apply it with the appropriate data policy.

You must configure at leaset one cflowd-template, but it need not contain any parameters. With no parameters, the data flow cache on vEdge nodes is managed using default settings, and no flow export occurs.
