[vpp-dev] Query on Inner packet Fragmentation and Reassembly
Hi , We have a use case, where we receive packets in a tunnel, and the inner packet may be fragments. If we want to reassemble the inner fragments and get one single packet, does VPP already have a framework that has this functionality. If it's already there, we can make use of it. I saw MAP plugin, but I am not able to see the place where it reassembles ipv4 fragments and outputs one single packet. Any inputs/examples please. -- Thanks & Regards, Murthy -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] Query on Inner packet Fragmentation and Reassembly
Hi Murthy, yes it does. Code is in ip4_sv_reass.c or ip4_full_reass.c. First one is shallow reassembly (as in, know 5 tuple for all fragments with having to actually reassemble them), second one is full reassembly.

[vpp-dev] Vectors/node and packet size
Greetings, This is my first post to the forum, so if this is not the right place for this post please let me know. I had a question on VPP performance. We are running two testcases, we limit it to single threaded and just using one core in order to reduce as many variables as we can. In the two testcases, the only thing that changes, is the size incoming packet to VPP. Using a 64 byte packet, we see a vectors/node of ~80. Simply changing that packet size to 1400 we see the same vectors/node fall down to ~2. This is regardless of pps… there seems to be a non-linear decrease in vectors/node with increasing packet size. I was wondering if anyone had noticed some similar behavior. 64- byte packets Thread 1 vpp_wk_0 (lcore 2) Time 98.9, average vectors/node 80.35, last 128 main loops 0.00 per node 0.00 vector rates in 1.2643e5, out 1.2643e5, drop 0.e0, punt 2.0228e-2 Name State Calls Vectors Suspends Clocks Vectors/Call VirtualFuncEthernet88/10/4-out active 90915 6249981 0 1.06e1 68.75 VirtualFuncEthernet88/10/4-txactive 90915 6249981 0 4.06e1 68.75 VirtualFuncEthernet88/11/5-out active 73270 6249981 0 9.27e0 85.30 VirtualFuncEthernet88/11/5-txactive 73270 6249981 0 4.05e1 85.30 arp-inputactive 2 2 0 3.51e41.00 dpdk-input polling116612933712499964 0 1.38e4 .01 error-punt active 2 2 0 5.56e31.00 ethernet-input active 2 2 0 1.47e41.00 gtpu4-encap active 90914 6249980 0 1.01e2 68.75 gtpu4-input active 73270 6249981 0 7.29e1 85.30 interface-output active 2 2 0 2.20e31.00 ip4-input-no-checksumactive 14557012499962 0 2.22e1 85.87 ip4-load-balance active 90914 6249980 0 1.77e1 68.75 ip4-localactive 73272 6249983 0 2.45e1 85.29 ip4-lookup active 21884018749943 0 3.79e1 85.68 ip4-punt active 2 2 0 1.27e31.00 ip4-rewrite active 23648218749940 0 2.75e1 79.29 ip4-udp-lookup active 73270 6249981 0 2.44e1 85.301400-byte packets Thread 1 vpp_wk_0 (lcore 2) Time 102.1, average vectors/node 2.37, last 128 main loops 0.00 per node 0.00 vector rates in 1.1841e5, out 1.1438e5, drop 4.0334e3, punt 1.9588e-2 Name State Calls Vectors Suspends Clocks Vectors/Call VirtualFuncEthernet88/10/4-out active2815250 5838981 0 8.18e12.07 VirtualFuncEthernet88/10/4-txactive2815250 5838981 0 1.25e22.07 VirtualFuncEthernet88/11/5-out active2765634 5839804 0 8.42e12.11 VirtualFuncEthernet88/11/5-txactive2765634 5839804 0 2.32e22.11 arp-inputactive 9 825 0 2.25e3 91.67 dpdk-input polling113698238812089787 0 1.44e4 .01 error-drop active 397116 411823 0 1.37e21.04 error-punt active 2 2 0 5.58e31.00 ethernet-input active 9 825 0 7.42e1 91.67 gtpu4-encap active2815249 5838980 0 2.21e22.07 gtpu4-input active3161920 6249981 0 2.10e21.98 interface-output active 2
Re: [vpp-dev] Vectors/node and packet size
In order for the statistics to be accurate, please be sure to do the following: Start traffic... “clear run”... wait a while to accumulate data... “show run” Otherwise, the statistics will probably include a huge amount of dead airtime, data from previous runs, etc. HTH...

Re: [vpp-dev] failed to init shmem: tcp_echo server not working
Hi,
You're seeing this issue because vpp_echo is trying to use the old
connection mechanism. The configuration I typically run with is the
following [1]
And launching vpp_echo with :
./vpp_echo socket-name /var/run/vpp.sock server uri tcp://10.0.1.1/1234
./vpp_echo socket-name /var/run/vpp.sock client uri tcp://10.0.1.1/1234
Hope this helps
Cheers
-Nathan
[1] /etc/vpp/startup.conf
unix {
interactive
log /var/log/vpp/vpp.log
cli-listen /var/run/vppcli.sock
exec /etc/vpp/vpp1.conf
}

Re: [vpp-dev] failed to init shmem: tcp_echo server not working
As replied on the private thread, vpp-echo needs to know about the api prefix you’ve configured (vpp1). Try adding “chroot prefix vpp1” to the list of options.

Hi Team, I realized that memif and corresponding sockets are tightly coupled. Means for example memif1 --> /run/vpp/memif1.sock --> application. We can not have multiple sockets for memif1, is my understanding correct? memif1 --> /run/vpp/memif1.sock if its already mapped, then we can not create memif1-->/run/vpp/memif2.sock please let me know if my understanding wrong and we can create multiple sockets for single interface? //Ravi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] How to active tx udp checksum offload #dpdk #mellanox
Hi,
I am using vpp stable/2005 code. I want to enable UDP checksum offload for tx .
I changed the vpp startup.cfg file -
## Disables UDP / TCP TX checksum offload. Typically needed for use
## faster vector PMDs (together with no-multi-seg)
# no-tx-checksum-offload
## Enable UDP / TCP TX checksum offload
## This is the reversed option of 'no-tx-checksum-offload'
*enable-tcp-udp-checksum*
But , still it is not activated . However all these tx offloads are available.
With VPP 19.05 , I was able to activate it by adding following piece of code in
./plugins/dpdk/device/init.c
case VNET_DPDK_PMD_CXGBE:
case VNET_DPDK_PMD_MLX4:
case VNET_DPDK_PMD_MLX5:
case VNET_DPDK_PMD_QEDE:
case VNET_DPDK_PMD_BNXT:
xd->port_type = port_type_from_speed_capa (&dev_info);
*if (dm->conf->no_tx_checksum_offload == 0)*
*{*
*xd->port_conf.txmode.offloads |= DEV_TX_OFFLOAD_TCP_CKSUM;*
*xd->port_conf.txmode.offloads |= DEV_TX_OFFLOAD_UDP_CKSUM;*
*xd->flags |=*
*DPDK_DEVICE_FLAG_TX_OFFLOAD |*
*DPDK_DEVICE_FLAG_INTEL_PHDR_CKSUM;*
*}*
break;
But, the above code does not work with vpp 20.05. I think , there is a newer
version of DPDK in this release.
Please let me know if I am doing something wrong.

Re: [vpp-dev] failed to init shmem: tcp_echo server not working
Hi,
I am unable to test if my server is up, could I be missing any configs in
interfaces/ vpp hoststack setup :
I configured vpp1 server with the following commands :
1./auto/home.nas04/skesavan/ *vpp* /build-root/install- *vpp* _debug-native/
*vpp* /bin/ *vpp* -c /etc/ *vpp* /startup.conf
2. -bash-4.2$ sudo ./configurevpp1.sh

3.cat ./configure vpp1.sh

if [ $USER != "root" ] ; then
echo "Restarting script with sudo..."

what could be missing potentially?
-vpp1 and vpp2 are two centos7 vms:have added strace output for the vpp2
connect call.
