Re: [vpp-dev] question about load balance

[薛欣颖]

Hi Neale,

I know what you mean. 
What should I do to match exactly I configured?  And ignore constraints 'a 
load-balance is always a power of 2'.

Thanks,
Xyxue

Hi Xyxue,
 
It does match your configuration. You requested a 2:1 ratio un-equal cost load 
balancing, you got a 5:3, which VPP considers to be close enough. It’s not 
exact because the number of buckets in a load-balance is always a power of 2.

Hi guys,

I'm testing routing load balance. There is a question : When I configured 1:2 , 
the actual effect 3:5. My configuration and more info is shown below:

configuration:
  ip route add 4.1.1.1/24 via ip4-address 1.1.1.2 interface host-eth0 weight 1
  ip route add 4.1.1.1/24 via ip4-address 2.1.1.2 interface host-eth4 weight 2

The actual effect:
4.1.1.0/24
  unicast-ip4-chain

Was it meant as tap v1 replacement?
If so, when do you plan to deprecate the old version?

[mohsin] dpdk-input, af-packet-input etc. Input graph nodes which receive

[mohsin] you can just add single label which you know interested packet should 
come from.

i.e. trace add af-packet-input 10

It will start tracing from af-packet-input and will report all the subsequent 
graph nodes which will process that received frame.

Hi,
In a typical scenario, we usually use wireshark or tcpdump to capture 
input/output packets from interfaces and we can use filters to filter them base 
on different criteria such as protocol.
My question is that : when VPP handles one interface, then this interface is 
out of kernel's control so we can't capture those packets using wireshark or 
tcpdump.

I read somewhere that there is a command named "trace" in VPP.

Re: [vpp-dev] VPP packet trace

[Fan Zhongyi]

Hi Deepak,

I am now trying exactly the same as you did before. But I can only use iperf 
between namespaces without VPP.

When I connect two namespaces with VPP, somehow with iperf on the client, it 
only shows connection timed out. 

ip netns exec vpp1 iperf3 -s
server listening on port 5201

Ip netns exec vpp2 iperf3 -c 172.16.1.2
connection timed out

I followed this wiki 
https://wiki.fd.io/view/VPP/Configure_VPP_As_A_Router_Between_Namespaces 
. I 
think I miss something or make some mistakes. Could you please tell me how can 
you set up TCP connection between namespaces with VPP?

Thank you in advance!

[vpp-dev] using iperf to see vpp performance between namespaces

[Fan Zhongyi]

Hi Team,

I have followed this wiki 
https://wiki.fd.io/view/VPP/Configure_VPP_As_A_Router_Between_Namespaces 
 that 
I can ping between two namespaces.

I can also use iperf between two namespaces without VPP.

But when I use iperf to see the VPP traffic performance between two namespaces, 
I can not get anything but connection timed out on the client.

ip netns exec vpp1 iperf3 -s
server listening on port 5201

Ip netns exec vpp2 iperf3 -c 172.16.1.2
connection timed out

Is that correct that I use iperf to see the traffic performance between 
namespaces? Or is there a better way to judge the performance of VPP you would 
recommend?

Thank you in advance!

Re: [vpp-dev] packet capture

[Mohsin Kazmi (sykazmi)]

Hello Holoo,


You can find examples of traces in VPP Uses Cases.


Specific to VPP packet tracing, please check the following link:


https://wiki.fd.io/view/VPP/Command-line_Interface_(CLI)_Guide#packet_tracer


Apart from that, debug CLI list down the commands:


vpp# trace ?
  trace addTrace given number of packets
  trace filter filter trace output - include NODE 
COUNT | exclude NODE COUNT | none
  trace frame-queuetrace frame-queue (on|off)
vpp#

I hope that it will help.

Subject: [vpp-dev] packet capture

Hi,
In a typical scenario, we usually use wireshark or tcpdump to capture 
input/output packets from interfaces and we can use filters to filter them base 
on different criteria such as protocol.
My question is that : when VPP handles one interface, then this interface is 
out of kernel's control so we can't capture those packets using wireshark or 
tcpdump.

===
What is an alternative in VPP for wireshark or tcpdump??
===

I read somewhere that there is a command named "trace" in VPP.
Is it correct?? if so, how to use it?? how to filter packets?? what is the 
representation format of packets?? how to filter them base on network stack 
layers??
I want to use this tool for debugging my scenarios which uses VPP as dataplane.

Re: [vpp-dev] problem in enabling nat44 and nat64 simultaneously

Hi,

NAT plugin currently doesn’t support same output interface for NAT44 and NAT64.

Hi,
For testing nat64 and nat44 with following configuration, I have problem in 
output traffic of nat44. The output traffic goes to nat64-out2in node.
I checked the graph path, how can fix this problem? Anyway is it common to have 
nat44 and nat64 in one interface at the same time?



set interface ip address GigabitEthernet0/4/0 
11.11.11.100/24
set int nat44 in GigabitEthernet0/4/0
set int nat44 out GigabitEthernet0/5/0
nat44 add address 192.168.40.20 - 192.168.40.30
set int state GigabitEthernet0/4/0 up
set int state GigabitEthernet0/5/0 up

set int ip address GigabitEthernet0/4/0 2002::2/64
set int ip address GigabitEthernet0/5/0 192.168.5.2/24
ip route add ::/0 via 2002::1
set int nat64 in GigabitEthernet0/4/0
set int nat64 out GigabitEthernet0/5/0
nat64 add prefix 1:2:3::/96
nat64 add pool address 192.168.50.1 - 192.168.50.19
