Adding New API for Packet duplication

[Vashung Muilung]

Hello,

 I am adding new api for packet duplication using netem duplicate at topology : interface class. And Encounter an error on testing. 

The test-case works fine at  /   directory( i.e your cloned folder)  but  does not work in /nest/test/   directory. 

It gives an Attribute error.

1. Testcase at /  directory.

a. Screenshot of working testcase.

b. Another working example for packet duplication

The same code when run on different directory: 

say ./nest/test/

AttributeError: 'Interface' object has no attribute 'set_packet_duplication'

API: set_packet_duplication()

Testcase code:

Please suggest what could be the problem getting attribute error.

Thannks

Hey Vashung, I suspect you have multiple versions of nest installed (one version installed from source, another version installed from PyPI using pip). 

Can you run "pip install -e ." from nest root directory and retry running program in nest/tests folder?

Hello sir,

Thank you for the reply, I did pip install -e . on the root directory.  I have the nitk-nest 0.3 version. 

And found some exceptions. Please check the screenshot.

Thank you Sir, 

I have solved my issue. I have multiple nest on my machine,  I remove one of older version.

And run my testcase, It worked.
