Question of 'Create a Two-Leaf, Two-Spine Topology'


when I do 'net add interface swp3 ip address 10.4.1.1/24' on leaf1, it will return 'Error: swp3 is not a physical interface on this switch'.

I check 'Getting started' of KVM/QEMU and find no configuration about swp3 in leaf1, why?

hi, @Pete B .
My version of VX is 3.6.2.
And I think the problem is because the QEMU/KVM document (https://docs.cumulusnetworks.com/display/VX/Libvirt+and+KVM+-+QEMU) does not set up 'swp3' but the example (https://docs.cumulusnetworks.com/display/VX/Create+a+Two-Leaf%2C+Two-Spine+Topology#CreateaTwo-Leaf,Two-SpineTopology-ConfigureCumulusVX-leaf1) used it. Is it?

Gotcha, yeah, that looks like it could be the issue. Let me check. Thanks @troyxxxx !

@troyxxxx I updated the KVM/QEMU chapter to add swp3 there. I hope I got it right — I don't have a Linux system to check against. Thanks for noticing this!
@Pete B, it seems right now. Thanks for checking that!
