However, there are other pieces (SNAT, ACL, etc) that are plugins. If your message is from VPE, it's not a plugin, and the "base message id" is 0 in this case. Are you using something close to the top-of-tree code? Or is this some point-release? The reason I ask is I think message id 11 is VL_API_GET_FIRST_MSG_ID_REPLY from vlibmemory/memclnt.api.h. So you are not registering to handle that message, and I think that message should be coming in semi-automatically if you have all of the parts lined up and loading correctly. (And furthermore, you should not be registering for that message reply.) Are you sure you are using the VPE module? You need to. HTH, jdl
