Unable to set SFP+ port to 10Gb negotiation on MS510TX
Hi, Since the peer device only support manual link speed. Is there any way to configue the MS510TX switch to 10Gb? Thanks,

No, and it's not required.

Are we facing fiber or copper SFP+ modules here?
On Ethernet copper links, IEEE clearly requires (mandtory) that the link speed -must- be negotiated for link speeds from 1000M and up (faster).
On fiber links there is -no- link speed negotiation, the default speed is used. So the only exception you might have to worry are 10G fiber modules, but you need a 1G link only. The solution is -not- using a 10G module, but install a 1G module instead.
Does this cause an issue, or is this some (likely outdated) idea or assumption that you "have" to define the link speed?

Since it shows link down when I set to auto.
Therefor on the MS510TX I would only able to set link speed to manual 1Gb Full and does not able to set to 10Gb Full.
