93240YC-FX2 and vPC config: works for ports 1-48 but not above?

[tenaro.gusatu.novici]

I'm able to apply vPC config on a leaf switch and I can see proper output when executing "show port-channel summary" on the leaf. However, when I try to use ports 49 and 50 (1/49,1/50), i.e. any 40 Gig port it doesn't work: even if it seems config is accepted I don't see anything in "show port-channel summary". Any ideas? First of all, is it a feature or a bug? Is there some different configuration required when using "routed" interfaces, i.e any of 12 QSFP 40/100G ports?

Hello! Those ports would need to be converted from [spine] uplink ports to downlinks. This doc should show you more info:

Thanks for reply. Link was useless but thanks to keywords (convert, uplink, downlink, leaf) in your description I was able to find correct doc:
