Thanks. I see /rest/interface/bridge/host to lookup Bridge Host. I guess that is intuitive but I did say I was new to MKT
And, my bad about the other two. I was trying to be thorough and reporting all the missing elements and just went alphabetically by the WinBox column headers. As you said Active Host Name is just host-name. And, Active Class ID is just class-id.
To learn the options I can use F1 in the Terminal. And, I can explore sample scripts. Is there any other suggestions for a reference guide to the data? Even a way to print all the data from every F1 level?
