Standard specification to get port speed ability

[li9270]

A port can be set to 40G or 100G.
If I set the port speed by gnmi_cli, how do I know the speed the port supported?
I see the 3.2 Capability Discovery in gnmi-specification.md, but not revelent to port ability.
Is there any any standard specification to get the port ability?
Thanks a lot !

The gNMI Capability RPC refers to the target's gNMI capabilities, not the hardware or software capabilities -- as such it will tell you the set of models that are supported.

Today, OpenConfig models do not have expose the capability of a particular hardware or software entity as operational data. We have discussed this before, but it has not been clear how this is practically consumed in a NMS context (it seems mainly a design-time decision), such that we haven't had contributors that have spearheaded this work.
