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!

Best,

[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!
