Hey,
The reason why your name doesn't match the request is related to your
code mixing vl_msg_id_t with vapi_msg_id_t. VPP internally assignes
message IDs at startup based on it's runtime configuration - plugins. If
a plugin is not loaded, it's API messages aren't loaded either. On the
other hand, VAPI IDs are constructed when the libvapiclient binary is
loaded and depend on included *.api.vapi.h files which your application
is using.
TLDR:
change:
printf("recv msg[%d] %s\n", resp->header._vl_msg_id,
vapi_get_msg_name(resp->header._vl_msg_id));
to:
printf("recv msg[%d] %s\n", resp->header._vl_msg_id,
vapi_get_msg_name(vapi_lookup_vapi_msg_id_t(ctx, resp->header._vl_msg_id)));
Regards,
Klement
