Hi Christian, Can you please elaborate on how to use DMA action of pass-through table for this? Is that like creating a separate pipeline for saving this metadata to the headroom space and in the next pipeline we use this metadata field for further lookups. And we will be using different keys for each of these pipelines. Is that so? Thanks for your help. Nidhia [Cristian] Yes, exactly. In the config/edge_router_upstream.cfg personality, you can see this taking place between PIPELINE2 (Pass-through) and PIPELINE3 (FlowClassification). The hash table mask approach can be used here to eliminate the PIPELINE2, but this was an after-thought at the time, which now is supported.
