Hi everyone,
I have a vdx-6740b and it seems that direct-attached cables are not being liked by the switch/NOS and I wonder - can we tell it to(straight & in caveman terms): no, it's okey, work!

many thanks, L.

Hi L,

No, unfortunately Unqualified SFP transceiver can not be forced up,
You can check which SFPs and cables are supported in Release notes for NOS

Best Regards,
I have now a sfp lead in that port that is 100% okey for it worked no problems in neighboring port, but port which was put down still is in state "adminDown".
Should it not automatically have gone up?

thanks, L.

Is 10G or 40G? do you have a license?
You can also check if license reserved for this port
dpod x/x/x (interface)
Can ask you - side note but related - if I reset config/switch to factory settings (btw, is how to do that in manuals?) will then all the licenses remain intact?

copy default-config startup-config [/code]License should stay
