Hi Laurent,
Trying to understand your setup:
Do you have :
100.100.101.x/24
TOR[.1] <-------------------->[.2] VLAN
So, is the interface on TOR end also on a vlan (with same id)?

Hey everyone,
Thank you for all the comments. Just trying to work my way through it! :)
Just as a sanity check, here is what it looks like on a fresh VPP (without any
config).
# Configure the VPP client with the proper vlan and IP address.
set interface state VirtualFunctionEthernet0/5/0 up
create sub-interfaces VirtualFunctionEthernet0/5/0 101
set interface state VirtualFunctionEthernet0/5/0.101 up
set interface ip address VirtualFunctionEthernet0/5/0.101
100.100.101.2/24<http://100.100.101.2/24>
I then have the following :
vpp# show interface address
VirtualFunctionEthernet0/5/0 (up):
VirtualFunctionEthernet0/5/0.101 (up):

I can see that I have 5 packets IN (5 ARP IN and 5 replies I assume)
No output from :
vpp# show ip neighbor
vpp# show ip neighbors
vpp#
Would that basic L3 configuration be enough to ping across the TOR to VPP?
Thanks!

As Neale replied earlier, adding L3 addr to the interface should implicitly
enable arp on it.
Thanks!

Hi Balaji
Its working for me. I was just trying to help "Laurent Dumont"
--
@Laurent Dumont<mailto:laurentfdum...@gmail.com>, can try it, even this arp
issue, is it working for you if you are adding neghbor IP?
set ip neighbor set ip neighbor [del] <intfc>
<ip-address> <mac-address> [static] [no-fib-entry] [count <count>] [fib-id
<fib-id>] [proxy <lo-addr> - <hi-addr>]
vpp#
Please try it with adding route and arp.
you can also use this, to set vlan on vf.
#ip link set eth0 vf 18 valn 101 --> u not required to create vlan interface
in vpp.

Mrityunjay Kumar.

Hi Mrityunjay,
Could you try adding an ip route and recheck.
I think ARP is enabled once ip routing is enabled.
Thanks

Hi everyone!
Thank you for the tips
The VF is created with the Trust On and spoofcheck disabled during the instance
creation.
vf 18 MAC fa:16:3e:92:30:f1, spoof checking off, link-state auto, trust on
I had a change to test this a bit more. It looks like the issue is specifically
with passing tagged traffic between the TOR and VPP.
I've added the VLAN101 on the TOR and the following on the VPP side.
set interface state VirtualFunctionEthernet0/5/0 up
create sub-interfaces VirtualFunctionEthernet0/5/0 101
set interface state VirtualFunctionEthernet0/5/0.101 up
set interface ip address VirtualFunctionEthernet0/5/0.101
100.100.101.2/24<http://100.100.101.2/24>
vpp# show int address
VirtualFunctionEthernet0/5/0 (up):
VirtualFunctionEthernet0/5/0.101 (up):
L3 100.100.101.2/24<http://100.100.101.2/24>
local0 (dn):
But now, if I look at the packets in error.
vpp# show error
Count Node Reason
5 dpdk-input no error
451 arp-disabled ARP Disabled on this interface
Is there a way to "enable" ARP on the l3 interface?

This issue, we have seen on centos as well. Just for work around,
ip link set promisc on eth0 #[eth0 --- PF interface]
ip link set eth00 vf 0 spoofchk off #[give your vf id ]
ip link set eth0 vf 0 trust on,
, But you will see other packet on vpp VF interface as well.
Can you try with IPv6, you will see more surprises. :)

Hi!
I was doing some initial experimentation with VPP/SRIOV/DPDK and I just wanted
to see if some of the things I was experiencing we're expected. I was looking
at understanding the baseline behavior for something like VPP + DPDK.
I have a small test POC with the following topology.
VM Ubuntu 18.04( with the "linux-image-extra-virtual" package) ---> (VPP +
DPDK + IP address on the VPP interface) ---> VF ---> PF (compute with SRIOV on
X710 cards) ---> TOR interface - untagged.
What I am seeing :
1. VPP is telling me I have both RX and TX packets.
2. That said, no ARP entry for the TOR is seen on VPP
3. The interface on the TOR is also not seeing any ARP entry for the VPP
interface. The TOR is also indicating that RX and TX packets are present.
Are there any inherent limitations to the ARP with VPP/DPDK?
One weird thing is that trying to show the ARP from VPP doesn't seem to be a
valid command :
vpp# sh ip arp
show ip: unknown input `arp'
Here are some more debugging output.
