}api-trace {
## This stanza controls binary API tracing. Unless there is a very strong reason,
## please leave this feature enabled.on
## Additional parameters:
##
## To set the number of binary API trace records in the circular buffer, configure nitems
##
## nitems <nnn>
##
## To save the api message table decode tables, configure a filename. Results in /tmp/<filename>
## Very handy for understanding api message changes between versions, identifying missing
## plugins, and so forth.
##
## save-api-table <filename>
}## These values control various aspects of the binary API interface to VPP.

api-segment {## Sets the prefix prepended to the name used for shared memory (SHM) segments. ## The default is empty, meaning shared memory segments are created directly in ## the SHM directory ‘/dev/shm’. It is worth noting that on many systems ‘/dev/shm’ ## is a symbolic link to somewhere else in the file system; Ubuntu links it to ‘/run/shm’.# prefix /run/shm## Sets the user ID or name that should be used to set the ownership of the shared memory ## segments. Defaults to the same user that VPP is started with, probably root.# uid root## Sets the group ID or name that should be used to set the ownership of the shared memory ## segments.
