Hi Alok, VCL, on master, defaults to no scope set. Local and global scope are set only if requested in vcl.config as “app-local-scope” or “app-global-scope” or if set via environment variables, like in your example lower. For more details check vcl_cfg.c. Session layer interprets no scope set as global scope only, so as long as no env variables are set and vcl.conf is like the one you have lower, global scope should be the one the app gets.
Now, regarding the sock test server and client, are you testing through the stack or cut-through connectivity? If the latter, then you need the local scope to be configured, otherwise cut-through connections don’t work. Also, take a look at [1] instead of sock_test_client/server apps if you’re interested in through the stack throughput testing. Iperf can also be used for cut-through connections but the only example you can find is here [2], so you’ll have to parse a bit of python to understand it. Hope this helps, Florin [1] https://wiki.fd.io/view/VPP/HostStack/LDP/iperf <https://wiki.fd.io/view/VPP/HostStack/LDP/iperf> [2] https://git.fd.io/vpp/tree/test/test_vcl.py#n287 <https://git.fd.io/vpp/tree/test/test_vcl.py#n287> > On Jul 11, 2019, at 3:16 PM, Alok Nikhil (anikhil) via Lists.Fd.Io > <anikhil=cisco....@lists.fd.io> wrote: > > I was following the discussion on this thread - VCL-Error > <https://lists.fd.io/g/vpp-dev/topic/vcl_error/23802581?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,40,23802581> > That led me to believe VCL starts with a global-scope as the default. > However, I tried a hosting the sock_test_server and the client cannot connect > unless I export VCL_APP_SCOPE_LOCAL=true > > This is what my /etc/vpp/vcl.conf looks like > vcl { > heapsize 1024M > rx-fifo-size 4000000 > tx-fifo-size 4000000 > api-socket-name /var/run/vpp/vpp-api.sock > } > > Is the default behaviour now changed? -=-=-=-=-=-=-=-=-=-=-=- > Links: You receive all messages sent to this group. > > View/Reply Online (#13493): https://lists.fd.io/g/vpp-dev/message/13493 > Mute This Topic: https://lists.fd.io/mt/32435763/675152 > Group Owner: vpp-dev+ow...@lists.fd.io > Unsubscribe: https://lists.fd.io/g/vpp-dev/unsub [fcoras.li...@gmail.com] > -=-=-=-=-=-=-=-=-=-=-=-
