I think I found it. vlib_frame_queue_main_init (sm->in2out_output_node_index, 0); So, it will be passing to the in2out node of the next core.

Re: [vpp-dev] NAT handoff node graph question
Hi Damjan, Thanks for the reply. I am not very familiar with VPP yet. Are you suggesting that the pkt will start its journey all the way from dpdk-input on the new core? Can't we just send the pkt directly to nat44-in2out node on the new core? In the code, I see that, we are calling vlib_get_worker_handoff_queue_elt() with the fq_index, and the next_worker_index. If I am reading the code right, fq_index is the index of the in2out node. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] NAT handoff node graph question
Hello, Once handoff node decides to handoff a pkt to another core, which node on the other core picks the pkt up? I am using 1807, and it seems like nst44-handoff-classify will send the pkt to either nat44-in2out-worker-handoff or nat44-out2in-worker-handoff node. nat44-in2out-worker-handoff and nat44-out2in-worker-handoff send the pkt to nat44-in2out and nat44-out2in respectively if the pkt should be processed in the current core. However, it is not clear to me which nodes gets the pkt after handoff if the pkt needs to be processed by another core.

[vpp-dev] ipsec questions
Hello every one im new to vpp ipsec and i saw there has been an improvment in version vpp 19.01 for ipsec. i have a couple of questions regarding ipsec on vpp. 1. after that i have new port name lets say "ipsec0", is there a unique identifier that will show from what *ikev2 profile it has been created* ? (if i have many connections i want to know which one is which for status and statistics...) 2. can i use multiple isakmp policies (ans esp also )for a *single ikev2 profile* in vpp ( ikev2 profile set pr1 ike-crypto-alg ike-integ-alg ike-dh )?? for a eample in strongswan: conn %default keyexchange=ikev2 authby=secret type=tunnel *ike=aes256-sha2_512-modp2048,aes128-sha1-ecp384,aes128-sha1-modp1536!* dpdaction=clear dpddelay=3 dpdtimeout=15 mobike=no if so how is the best practive - i dont think using 3 diff profiles with just diffrent ike profiles will do the trick becouse i can end up with multipule connections that i didnt wanted... thanks in advance!!! -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] VPP stats
Hi Raj,
In case this might help, there is a config for statseg for VPP 18.10 in a
dockerfile entrypoint here:
https://github.com/cisco-ie/vpp-lab/blob/master/hc2vpp/entrypoint.sh#L21
It seems like the following should work because, default config is
/run/vpp/stats.sock
statseg {
default
}

Re: [vpp-dev] VPP stats
Hi Ole,
I tried various combination of stats and statseg in config file but no
joy. For example this conf gives error in 18.10. though by manual it
seems ok.
stats { socket-name /run/vpp/stats.sock }
statseg { size 128M }
It would be great if you can point to the documentation for 18.10 or a
sample conf for 18.10
Thanks and Regards,
Raj

[vpp-dev] getting segfault in execution of vpp 19.01 having nat configuration with trex

Here is my vpp configuration: https://paste.ubuntu.com/p/czRf8g6Nt6/ This is trex config file: https://paste.ubuntu.com/p/DXHdQf77mC/ This is my trex yaml file containing pcaps: https://paste.ubuntu.com/p/Xdngz3NWRP/ I used this command to start trex test. ./t-rex-64 -f cap2/sfr.yaml --cfg cfg/trex_config_nat.yaml -c 4 -m 8 --learn-mode 3 -d 3600 Here is back-trace of gdb. https://paste.ubuntu.com/p/qxbHP8PVYS/ It would be appreciated if you can help me to fix this SIGSEGV problem.
