PHP API + dynamic pppoe

I’m using API for PHP. I’ve got a problem with getting dynamically added interfaces, such as pppoe. To be more precise,
as a result of these commands:(API example) /interface/getall or /interface/print I get complete data from static interfaces but the data I get from dynamic
interfaces are incomplete. It lacks such data as [name] which is equal to pppoe user login in my case. Thesame problem /queue/simple/print and other places where
dynamically added interfaces occures except /interfaces/pppoe-server/print, but these data cannot be connected with
/queue/simple/print
My aim is to change rate limits dynamically without disconnecting clients from mt.

well, you cannot change settings on dynamic interface

I only want to change simple queue and as far as I know this is possible by “set” command. I’ve done it using winbox,telnet etc.

The problem is in API capabilities?

dynami or static queue?
