[2.0.0b4] Unable to open projects with IOU created in 1.5.3

[bpozdena]

Hi,

when I open projects from 1.5.3 on 2.0.0b4, the file is converted with no errors. However all IOU devices change icons to PC (null) and all interfaces change names incorrectly.

I tried to manually edit the file, but I could not make it work properly. I just started the project from scratch. But I wanted to report it...

Windows 10/GNS3 2.0.0b4
Sairus

After conversion:

"node_id": "99399dc5-33ba-44d7-b506-edd78fb6fbe2",

},

WHen I create a new project with IOU the format is correct:

Can you share your .gns3 before conversion?

Thanks

project.gns3.txt
Here it is as I saved it in 153.

I think the syntax for the port name format is Ethernet{segment0}/{port0}. I will fix the conversion process

[bpozdena]

When I manually edited the IOU devices with "port_name_format": "Ethernet{segment0}/{port0}" , the interfaces were named as Ethernet0/0, Ethernet1/1, Ethernet2/2 and so on. While these IOU devices actually have modules installed, each with four interfaces. The interface names should be Ethernet0/0, Ethernet0/1, Ethernet0/2...Ethernet4/0, Ethernet4/1 and so no depending on the number of modules.

It works great in new projects created in 2.0.0b4 but not after conversion from 153.

port_segment_size should be 4

[julien-duponchelle]

The original file was created with which version of GNS3?

[julien-duponchelle]

Thanks for the report I fixed the conversions issues.

[bpozdena]

Yes, I missed that. port_segment_size should be 4 - Thanks.
The original was created in 1.5.3.
