MIKROTIK OID Question

Hi

I was wondering if anyone knows the oid for mikrotik that gives the port status: weather it is full duplex, half duplex or down..


thanks

Maybe here something to use:
http://forum.mikrotik.com/t/event-interface-half-duplex/51814/1

its a bit confusing that thread. Anyone have any other ways of identifying the full duplex, half duplex and ports that are down?

I know there is interface status up or down, not sure about the duplex
