[ovs-discuss] OVS doesn't apply action in packet_out message

2018-02-19 Thread S hj 
I have some OVSs connected to ONOS controller.
OVS1---OVS2OVS3

when OVS1 wants to send packets to OVS3, OVS2 sends packet_in messages to
the controller including ARP message and ONOS sends packet_out messages
contain OFPP_FLOOD as an action.

However, OVS2 doesn't flood the flow toward the OVS3.
Is there any way to find out why OVS2 by receiving the packet_out,
doesn't apply the action on the flow?


Thanks,

Re: [ovs-discuss] ovs-vswitchd 100% CPU in OVN scale test

2018-02-19 Thread aginwala 
Hi All:

As per the discussions/requests by Mark and Numan, I finally reverted the
mtu patch (commit-id 8c319e8b73032e06c7dd1832b3b31f8a1189dcd1) on
branch-2.9 and re-ran the test with 10k lports to bind on farms, with 8 LRs
and 40 LS ;and results improvised.  Since ovs did not go super hot, it did
result in completion for 10k ports binding to HVs in 5 hrs 28 minutes vs 8
hours with mtu patch.  Thus, the extra strcmp did add the overhead. Cpu
idle graph of farm with 50 Hvs running 2.9 with/without mtu is available @
https://raw.githubusercontent.com/noah8713/ovn-scale-test/4cef99dbe9a0677a1b2d852b7f4f429ede340875/results/overlay/farm_cpu_2.9.png
which indicates ;running non-mtu patch had more idle cpu percentage vs with
mtu patch. In addition, I have also captured ovs-vswitchd process cpu util
on farm since ovs itself was creating a bottleneck by slowing down the port
binding on the computes.Graph is available @
https://raw.githubusercontent.com/noah8713/ovn-scale-test/scale_results/results/overlay/ovs-vswitchd_2.9_util.png
Hence, overall performance improved which resulted in faster completion of
all 10k port bindings.

[ovs-discuss] Is a new field in flow.h necessary for matching on a custom v6 extension header?

2018-02-19 Thread Alan Kayahan 
Hello,

I have a custom v6 extension header, in which I would like to perform an
LPM match on only one 32bit field.

Since an extension header is technically not a new field, do I still need
to introduce anything in the struct flow?

In miniflow_extract(), what I did was to add a case
in parse_ipv6_ext_hdrs__ as (*nw_proto == IPPROTO_TRH) where IPPROTO_TRH is
my custom proto number, and parse the *datap to my struct trh_hdr, then
data_try_pull. Is this the appropriate approach?

If yes, what would the appropriate way be for accessing the 32bit field in
trh_hdr to perform the match?

Thanks,
Alan

i'm familiar with the procedure. I can build dpdk 17.11 but has this

Here https://community.mellanox.com/thread/3545  the answer to the same error

Re: [ovs-discuss] ovs-dpdk cannot add a dpdk mellanox port

2018-02-19 Thread Olga Shern 
Hi Avi, 

Please try the following commandovs-vsctl --timeout 10 add-port br-phy 
dpdk0   -- set Interface dpdk0 type=dpdk options:dpdk-devargs=mlx5_0 

You need to specify port name, mlx5_0 or mlx5_1 according  ibv_devinfo output 

Starting DPDK 18.02 and 17.11.2 you will be able to use PCI address as OVS   
devargs parameters. 

Best Regards,
Olga

Hi
I cannot add mellanox dpdk port - and  I don't find any reference for this for 
new ovs versions I get  an error message when typing this command
ovs-vsctl --timeout 10 add-port br-phy dpdk0   -- set Interface dpdk0 type=dpdk

Re: [ovs-discuss] [ovs-dev] DPDK: How to send packets from one OVS bridge to another OVS bridge while running in the same user space ?

2018-02-19 Thread Kapil A 
Hi Jan,

Thanks sharing the information. For my use case, i cant run a secondary VM,
so need to look for DPDK ring port option.

I didn't find much information on how to use a DPDK ring port to connect
two Bridges. i have added a dpdkr0  to a dpdk bridge, but not sure how to
connect it to another bridge. Can you please share light on how to connect
two bridges using DPDK ring ports.

Re: [ovs-discuss] OpenStack profiling with networking-ovn - port creation is slow

2018-02-19 Thread Daniel Alvarez Sanchez 
Just for completeness, I did some tests with and without the
JSON parser C extension [0]. There's no significant gain (at
this point), maybe when we add the port groups it's more
noticeable though. Average time without it's been 2.09s
while with the C extension it's been 2.03s.

@Han, I can try rebase the patch if you want but that was
basically renaming the Address_Set table and from Ben's
comment, it may be better to keep the name. Not sure,
however, how we can proceed to address Lucas' points in
this thread.

Thanks,
Daniel
