1. A method comprising:

  • at a transport network interface apparatus associated with a first Fiber-Channel port that is to communicate over a transport network with a second Fiber-Channel port, monitoring link establishment frames originated by and communicated between said first Fibre-Channel port and said second Fibre-Channel port; and

    at the transport network interface apparatus, based on said link establishment frames, determining said link status between said first Fibre-Channel port and said second Fibre-Channel port and port types among a plurality of possible port types of said first and second Fibre Channel ports using a state machine, wherein flow through states of the state machine depends on the link status and port types of the first Fibre-Channel port and the second Fibre-Channel port according to the link establishment frames exchanged between the first Fibre-Channel port and the second Fibre-Channel port.
