The attempt failed！ Adding static mapping to bvi or tap-in-OS both does not
work.
Is there any cmd that can remove the NAT logic of udp-4789 from NAT44？
Help
please！

If by chance you are in a bridge setup, then you can use the new l2 feature arc
- there is an arc that sees exactly that - packets that are neither ipv4 nor
IPv6 - you can see the https://gerrit.fd.io/r/#/c/15165/ where I switched the
acl plugin over to it...

Hi Stephen,
No, we don’t support RCU. Wouldn’t rw-locks be enough to support your usecases?

Is it possible to do Read Copy Update with VPP? Either using Userspace RCU
(https://librcu.org)
or manually. RCU is very efficient way to handle read mostly tables and other
dynamic cases
such as plugins.
The several things that are needed are non-preempt, atomic update of a pointer
and a
Yes, you can just use device-input feature arc instead.
Please note that packets on that arc are not (optionally) assigned to
sub-interfaces yet.
So if you have vlan subinterface, packets will show up as main interface
packets and with
original l2 header.

Hi,
I am using DPDK Plugin
I want to write a node which will get to observe all the non-IP packets.
By observe, I mean that I want my node to see the non-IP packets, but
when I return from my node, the packets should traverse the original
graph of VPP which they would have followed had my node
Right now it is main thread. there is a plan to make this per-thread. ETA
unknown...

Hi,
I understand that when I do something like the following --
clib_file_t template = {0};
template.read_function = my_read_cb;
template.file_descriptor = my_fd;
template.private_data = my_data;
my_handle = clib_file_add (_main, );
Then my_read_cb will be called whenever the my_fd has data
Cool, glad you found what you needed...

Thanks a bunch Dave !
The vlib_buffer_add_data(...) does the trick for me ! All that I
really had to do was to just set up the following fields in the
vlib_buffer_t for the buffer index created by the function
vnet_buffer (b)->sw_if_index[VLIB_RX]

The NAT plugin is tossing vxlan out-to-in packets. You’ll get different results
if you add a static mapping for (UDP, 4789) packets - maybe not the desired
result, but at least a different result...

Dear Emma,
the behavior you are observing is expected. Since we do not do
in-flight reassembly, in order to make the ACL work for the fragment
we have to do first-match on a relaxed rule derived from L4 rule that
would have matched that packet.
I think just issuing "set acl-plugin
Hi Dear VPP
When I was trying to test fragmentation feature in VPP, I encountered a
problem.

However, I found some error!
