The NAT Flow feature is an unusual NAT feature that allows the translation of traffic streams in ways that go beyond the typical translations achieved with NAT. In that sense, the feature is not strictly a standard NAT feature; it can be seen as a combination of NAT and DirectFlow.

This feature extends the capabilities of Tap Aggregation traffic steering to allow for using traffic policies.

Line cards, fabric cards, and switch cards now alert the user whenever a card consumes excessive power. There are
