Abstract

The link status of a Fibre-Channel link interconnecting two Fibre-Channel ports may be determined by a third entity distinct from the two Fibre-Channel ports. The third entity may be a transport interface used to connect one of the Fibre-Channel ports to a transport network that carries the link. The transport interface may also learn the Fibre-Channel port types of the two ports.

Claims (23)

1. A method for operating a network interface to determine status of first and second Fibre-Channel ports that communicate via said network interface, said method comprising:
monitoring link establishment frames communicated between said first Fibre-Channel port and said second Fibre-Channel port; and based on said link establishment frames, determining a link status between said first Fibre-Channel port and said second Fibre-Channel port.
2. The method of claim 1 wherein said first Fibre-Channel port comprises an N_Port and said second Fibre-Channel port comprises an N_port.
3. The method of claim 1 wherein said first Fibre-Channel port comprises an N_port and said second Fibre-Channel port comprises an F_port.
4. The method of claim 1 wherein said first Fibre-Channel port comprises an E_port and said second Fibre-Channel port comprises an E_port.
5. The method of claim 1 wherein determining said link status comprises determining port types of said first Fibre-Channel port and said second Fibre-Channel port.
6. The method of claim 1 wherein determining said link status comprises determining that a link has been established.
7. The method of claim 1 wherein determining said link status comprises determining that a link establishment frame is expected from one of said first Fibre-Channel port and said second Fibre-Channel port.
8. Apparatus for operating a network interface to determine status of first and second Fibre-Channel ports that communicate via said network interface, said apparatus comprising:
a first connection to a local Fibre-Channel port;
a second connection to a remote Fibre-Channel port via a transport network; and a processor that monitors link establishment frames communicated between said first Fibre-Channel port and said second Fibre-Channel port via said network interface and, based on said link establishment frames, determines a link status between said first Fibre-Channel port and said second Fibre-Channel port.
9. The apparatus of claim 8 wherein said first Fibre-Channel port comprises an N_Port and said second Fibre-Channel port comprises an N_port.
10. The apparatus of claim 8 wherein said first Fibre-Channel port comprises an N_port and said second Fibre-Channel port comprises an F_port.
11. The apparatus of claim 8 wherein said first Fibre-Channel port comprises an E_port and said second Fibre-Channel port comprises an E_port.
12. The apparatus of claim 8 wherein said processor determines port types of said first Fibre-Channel port and said second Fibre-Channel port.
13. The apparatus of claim 8 wherein said processor determines that a link has been established.
14. The apparatus of claim 8 wherein said processor determines that a link establishment frame is expected from one of said first Fibre-Channel port and said second Fibre-Channel port.
15. Apparatus for operating a network interface to determine status of first and second Fibre-Channel ports that communicate via said network interface, said apparatus comprising:
means for monitoring link establishment frames communicated between said first Fibre-Channel port and said second Fibre-Channel port; and means for, based on said link establishment frames, determining a link status between said first Fibre-Channel port and said second Fibre-Channel port.
16. The apparatus of claim 15 wherein said means for determining said link status comprises means for determining port types of said first Fibre-Channel port and said second Fibre-Channel port.
17. The apparatus of claim 15 wherein said means for determining said link status comprises means for determining that a link establishment frame is expected from one of said first Fibre-Channel port and said second Fibre-Channel port.
18. Apparatus for operating a network interface to determine status of first and second Fibre-Channel ports that communicate via said network interface, said apparatus comprising:
means for monitoring link establishment frames communicated between said first Fibre-Channel port and said second Fibre-Channel port; and means for, based on said link establishment frames, determining a link status between said first Fibre-Channel port and said second Fibre-Channel port.
19. The apparatus of claim 18 wherein said means for determining said link status comprises means for determining port types of said first Fibre-Channel port and said second Fibre-Channel port.
20. The apparatus of claim 18 wherein said means for determining said link status comprises means for determining that a link establishment frame is expected from one of said first Fibre-Channel port and said second Fibre-Channel port.
21. A computer program product for operating a network interface to determine status of first and second Fibre-Channel ports that communicate via said network interface, said computer program product comprising:
code that monitors link establishment frames communicated between said first Fibre-Channel port and said second Fibre-Channel port;
code that, based on said link establishment frames, determines a link status between said first Fibre-Channel port and said second Fibre-Channel port; and a computer-readable storage medium that stores the codes.
22. The computer program product of claim 21 wherein said code that determines said link status comprises code that determines port types of said first Fibre-Channel port and said second Fibre-Channel port.
23. The computer program product of claim 21 wherein said code that determines said link status comprises code that determines that a link establishment frame is expected from one of said first Fibre-Channel port and said second Fibre-Channel port.
