Hi Dear VPP guys,
I would like to do some investigation about AVX512 instruction
support in VPP, I saw there are already some implementations but AVX2 is still
the default option. Could anybody tell me how to enable AVX512 in VPP?
Appreciate for your kindly help in advance.
Hi Neale,
Thanks for replying. I think you’ve pointed out the root cause. The cmds
provides the response like this:
vpp# show crypto engine
No crypto engines registered
vpp# show ipsec backend
IPsec AH backends available:
Name Index Active

Attaching the version information also. And I install VPP through apt.

Looking at the docs, I think you need to set one using the:
set crypto handler cipher [cipher2 cipher3 …] engine
Not sure, what’s the default behavior.

Hi Balaji,
I checked the docs and tried to set the handler engine. Since there’s no
example for the command, I’m not sure if I’m setting the right value for
‘cipher’ here. I tried with different values, but it just returns error msg
like this:
vpp# set crypto handler aes-128-cbc engine
failed
Hi Raj,
I think your analysis is spot on. Thank you!
How you're a VPP PPPoE expert __ do you have some suggestions on a fix?

I could do some more analysis of this issue and I think I have

Possiblly because your loaded crypto engine/backend does not support the

All of the docs have moved to the main fd.io site: See
https://fd.io/documentation/ and more specifically
https://fd.io/docs/vpp/master/.
Eventually, one would expect that search results will improve. It's possible
that we could plant a "301 Moved Permanently" page on readthedocs.
I'll ask
Hi Ruoyu,
Could you please post the ipsec error message on create?
SA create usually indicates an issue with hardware. You might want to try if
rebooting the instance resolves it?

Hi,
I tried to use vpp to enable IPSec in my environment. And when I tried to
create a SA, I always got an error for that.
Detailed configs look like this:

Hi, I got VPP crashed when trying to add more nsh map.
My case is this:
client -> router1 (vpp, 192.168.1.34) -> node1 (vpp, 192.168.1.37) -> ...
-> node2 (vpp, 192.168.1.40) -> ...

with node1/2:

Hi,
Currently we only support setting of local ips for builtin applications, like
the one you’ve built lower. VCL and the message queue api currently do not
support this.
I guess we could add a VPPCOM_ATTR_SET_LCL_ADDR set attribute option and pass
that over the api. But before that, could

Shouldn't the usual solution of storing the index in the pool instead of the
pointer itself be enough?
Ie, use session_id as fixup_data, and use it in pppoe_fixup() to

That will work.
Looking into the fixup function, all that's used from the session is the
ergress interface. So only that needs to be 'pushed'. I suspect using the whole
session was a convenience for the orignal author, whoever that might have been

Yes. It is unidirectional stream from port 1 to port 4.

that xia port connected to port 1 is green and good. ixia port connected to
port 4 is green but has a red exclamation mark, which means ping does not

Hi Chuan,
Could you please try to reset the ixia controller connected to port 4?
I have seen issues with ‘!’ on ixia. Given the carrier on eth0 is down, I

I tried disabling autoneg on R740 side. It is not allowed too. If vpp
cannot allow two nics to be successfully added to the same vpp instance, it
seems to be a bug. Is it something which can be easily spotted in the code
base?
It is also not possible to enforce symmetricity on internet. The other
This looks like a DPDK issue, but I’ll let Damjan be the judge of that.
To see if this is a config issues, could you simplify your startup config by
- removing “workers 0” from the two nics and adding “num-rx-queues 2” to the
nics or to the default stanza, if you’re running with 2 workers

Restarting ixia controller does not help. We ended up with both ixia ports
having '!'.
We are not sure how ixia port plays a role here. eth0 interfaces are the
interfaces connecting two servers, not to ixia.

Hi Chuan,
I got the eth0 and eth1 mixed up. My bad.
Are these fiber or copper links? You may want to check if the cable is ok.
Also, please make sure you have crossover cable(if RJ) between the servers.
Thanks!

I rebooted the r230 machine and found the phy nic corresponding to eth has
autoneg off.

Settings for enp6s0f1:

Does vpp have some special requirements on nic types and cabling?

When two interfaces are in the linux, ping works.
On R740, we have

It plays a role if it is asymmetric at both ends. You could enable it at both
ends and check.

If I only put one phy nic, i.e., eth0, to vpp, 'sh hardware' shows it is
up. If I put both eth0 and eth1 in vpp, eth0 is always down. It seems
something is wrong with the nic or vpp does not support this type of
hardware?

Hi Chuan,
As Balaji said, probably it’s worth making sure the cable between the eth0 nics
is fine and that eth0 on R230 works as expected. For instance, you could double
check your setup by switching to linux drivers and trying a ping between the
two boxes.
Regarding “sh int”, it only shows
