Hi, Need few clarifications on IPFIX support in the latest VPP. I went thru' codebase of older releases and understand how IPFIX support has evolved from 16.09 thru' the latest, in terms of enhancements and refactoring from vnet/vnet/flow,classify to flowperpkt plugin and now as flowprobe plugin.
With latest VPP, I have few questions: 1) Flowprobe depends on vnet/ipfix-export for exporting flow data(template rewrite etc). But does flowprobe depend on VPP classifiers anymore, i.e. does it expect to create classifier table/session for flow matching? Where is the hash/lookup done? 2) Flowprobe seems TX only feature, is it supported for RX also? 3) What does it exactly mean "plugin generates ipfix flow records on interfaces which have the feature enabled"? Does it mean flow records are generated for "all" flows on that particular interface or can we selectively enable flow record generation on only specified flows? Thanks, harish
