Speed variable and operational speed doesn't match

Hello,
I’ve got a problem with the “speed” variable listed by the command “interface ethernet print detail” and the API string “/interface/ethernet/print” (or getall).

I don’t know the reason, but it seems that 1Gbps links are displayed as 100Mbps links (see image attached):

No problem, i.e., with 10Gbps links.

I’ve seen that this problem is present on different version of ROS 6 (6.22, 6.34.4, 6.37.1), could you please check it out?

Thank you very much!

Giuseppe
