Hi,
I have a problem when using *vec_validate* to allocate large memory size ( more
than 5G ) , I am sure that i have enough memory on my system,
but vec_validate take so long time to allocate memory how can i decrease this
delay time for allocate memory and how can calculate memory size
before
Hi dave
I am using 64 bit image ( -DCLIB_VEC64=1 ) and as I said, I can get vectors
with large size (more than 5GB)
My problem is not the size of vector it is time delay for allocation.
when I using vec_validate to allocate huge memory size it has a very very long
delay to response,
I don't ge
Hi,
Is it possible to use Ncurses library function on VPP CLI Command to have nice
view,
i used a basic sample but does not work, compile with -lncurses and use this
commands :
initscr(); /* Start curses mode */
printw("Hello World !!!"); /* Print Hello
Hi,
I tested VPP performance for CGNAT in Deterministic mode; While VPP is working
and has sessions, "show memory" command causes huge drop rates or when I want
to add another deterministic mapping it takes long delay (for memory
allocation) and again huge drop rate occurs that relate to memor
hi Matus
I know it will take some time when add new deterministic mapping.
But why "show memory" command has drop rate
Or why adding new deterministic mapping cause drop rate
Thanks !

Do you mean it is impossible to have packet processing and memory operation at
the same time,
for example doing vec_validate or vec_free when NAT plugging is working and
create new session.
I have drop rate when vec_free or vec_vlidate for memory size greater than 3GB.
What are your suggestion

I want to enable an INPUT node just for one worker and disable for others

if I config vpp without NAT (just routing) it works , but When Config for NAT I
have rx-miss on all interfaces.

hi Matus
Thanks for your answer, can you explain more about this issue?
You mean that I should rewrite "nat_ipfix_logging.c" file to works per thread
or "vnet/ipfix-export/flow_report"

Hi ...
I know that we need handoff mechanism when running multithread because traffic
for specific inside network user must be processed always on same thread in
both directions and We can not remove handoff node from NAT nodes ,because
handoff is faster than locking mechanism.
So the proble
*Hi Damjan*
*Thnaks for your answer,*
*I think it is possible (I encountered this problem) to have deadlock even when
I use separate CPU for handoff and NAT processing, Or same CPU with congestion

I want to use the L2 xconnect or L2 bridge feature on multiple interface , i.e
