[vpp-dev] Flowprobe/IPFIX export
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?

Re: [vpp-dev] VNET classifier table/session
Hi Andrew/all, I was going thru' some of the code/doc pointers. As I said I'm using relatively older VPP releases (16.09/17.01). With regards to IPFIX (using VNET classifier functionality), I do not see any support for sending real flow statistics via IPFIX templates. I just see that plain IPFIX templates can be sent out periodically to the collector but with no other information entities (except packetTotalCount which is manually calculated). So I am trying to know what is the minimum version we need to move forward with in order to claim basic IPFIX support? I see that 17.07 release added FlowProbe plugin which implements some of the information entities. Pls let me know.

[vpp-dev] VNET classifier table/session
Hi, Can you please provide few examples (with right syntax and little explanation) on to how to use VNET classify table and classify session in relatively older VPP releases. "classify table [miss-next|l2-miss_next|acl-miss-next ]" "\n mask buckets [skip ] [match ] [del]", "classify session [hit-next|l2-hit-next|acl-hit-next ]" "\n table-index match [hex] [l2] [l3 ip4] [opaque-index ]", Thanks, Harish -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Hi Dave,
Great, thanks for the quick reply.
Thanks for clarifying the same, I tried out a quick example and it seems
okay.

[vpp-dev] Heap allocation
Hi, I would like to pre-allocate separate heap space (outside of main heap) and be able to use the returned memory for my application's memory needs (just like malloc()). It seems we can have up to 256 heaps. Have few questions around this: 1) My understanding is that currently the main heap is allocated using clib_mem_init()/clib_mem_init_thread_safe() and the subsequent calls like clib_mem_alloc(size) will carve out memory from within the main heap and returned to clients (similar to glibc malloc()). Is this correct? If so, I would like to know how this is achieved since I don't see the returned pointer from clib_mem_init()/clib_mem_init_thread_safe() is being referenced or used anywhere. 2) Some applications are using mheap_alloc() directly to create new heap. Ex: void *heap; void *oldheap; heap = mheap_alloc (0, 10<<20); oldheap = clib_mem_set_heap (heap); .. .. clib_mem_set_heap (oldheap); << why is this required to write back oldheap into per-cpu heap? What I really like to know is once the heap is allocated how can we use it? Does it imply to have pools/hashes to be created to be able to use it? I'm expecting something which takes void *heap (created using mheap_alloc) and returns the requested memory for a given size from within the heap so that we don't need to use pools/hashes. Ex: void *foobar(void *mheap, size_t size); Is it possible? Thanks, Harish -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] SPAN feature backport
Hi, I are currently using VPP 16.06 release. We would like to enable SPAN feature (port mirroring) in 16.06, but it is available only in VPP 17.01 release and above. It seems SPAN module depends on vnet feature arc (vnet/feature/). So my question is can we bypass vnet feature arc using some workaround and backport it into 16.06? If so, how easy or difficult would be that? Are there any other alternates besides upgrading VPP? Thanks, Harish -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
