The most interesting feature of 802.3ah are:

  OAM - Operations and maintenance:
   o detailed link failure indication
   o MAC layer ping (Ethernet ping on layer2)
   o remote loopback control for diagnostics purposes
   o link monitoring
   x this is applicable to the generic ethernet layer

  Ethernet Link aggregation
   o aggregation of links with differing speeds and latency
   o ordered delivery of frames
   o dynamic discovery and addition/removal of links
