If vendors start playing games with license fees per feature (to pad their revenues), then one either conform or work-around them. If this pertains to netflow, I've done something like the following in the past: * span traffic to pkt collector * on pkt collector, run something like "fprobe" to convert raw pkt to flow format * export flow to said flow collector
This man-in-the-middle approach may be somewhat silly to bypass licensed netflow feature, and could be moot if one needed another license to do spans.
