Hi Florin,

The socket name is matching in both vcl.conf and startup.conf, pls take a
look at the below two files attached: -
Let me know if any other config is missing or is wrong.

vcl.conf
==================
vcl {
  rx-fifo-size 4000000
  tx-fifo-size 4000000
  app-scope-local
  app-scope-global
  api-socket-name /tmp/vpp-api.sock
}

startup.conf
===================
unix {
  nodaemon
  log /var/log/vpp/vpp.log
  full-coredump
  cli-listen /run/vpp/cli.sock
###  gid vpp
}

session { evt_qs_memfd_seg  }
socksvr { socket-name /tmp/vpp-api.sock}

NOTE: -
=======
I had exported the below two env variables also.
export VCL_CFG=/etc/vpp/vcl.conf
export LDP_PRELOAD=/usr/lib64/libvcl_ldpreload.so

I have attached these two files (vcl.conf and startup.conf) for your
reference.

Pls let me know if we are missing something or is something wrong

Regards,
Vijay Kumar N
