[vpp-dev] NO REPLY FROM VPP FOR PUNT SOCKET REGISTRATION
Hi All,
I am not getting a reply from vpp.
Any pointers will be helpful.
Thanks in advance.

come out.

Re: [vpp-dev] NO REPLY FROM VPP FOR PUNT SOCKET REGISTRATION
Hi Ole,
My requirement is to sniff the NTP packets using a raw sockets, and process
them in my application.
I new bee to VPP world.
>>The message IDs are dynamic and depend on which plugins are loaded.
i do not understand exactly.
Thanks,
