Cant skip slots

[rjsullivan25]

Describe the bug
Can't populate slots 4,5,6 with slots 1,2,3 unpopulated on 7200 router. Can't leave slot 0 unpopulated which was possible in earlier releases.

GNS3 version and operating system (please complete the following information):

• OS: macOS 10.1.5.5
• GNS3 version 2.2.8
• Any use of the GNS3 VM or remote server (ESXi, bare metal etc.) Local server

To Reproduce
Steps to reproduce the behavior:

1. Slot 0 cannot be left unpopulated
2. If slots 123 are left unpopulated, with 4,5,6 populated with say GE connector, the GUI shows incorrect network connections.

Behaviour was different in versions of GNS before 2.0

Thanks for responding grossmj. I've not reported a bug on github before.

No worries, I am going to investigate.

Thanks Jeremy. Ideally what I'd like to be able to setup is a 7200 router template with all the slots empty. Currently GNS3 adds a C7200-IO-FE adapter to slot 0 be default. I'd also like the option to add a PA-GE adapter to individual slots in specific 7200 router nodes on the workspace. The interface labels should then show the correct interface ie g1/0, g2/0 etc. The pre-2.0 version of GNS3 allowed one to do this.

Slot 0 cannot be left unpopulated

An adapter in slot 0 is mandatory with c7200. This is a special adapter (I/O controller). In previous version this could be left empty but a C7200-IO-FE adapter was silently added by Dynamips.

I wouldn't recommend other adapters for slot 0 because I remember I had issues with C7200-IO-GE-E for instance. Also, when launching dynamips, C7200-IO-2FE and C7200-IO-GE-E are marked as NOT WORKING. So just to be safe I would stick with C7200-IO-FE

If slots 123 are left unpopulated, with 4,5,6 populated with say GE connector, the GUI shows incorrect network connections.

Correct, there is a problem with the network connection labels.
