Abstract

Provided are a method and device for address assignment for adaptor interfaces. An initial configuration is maintained assigning multiple local interfaces to one initial local address. For each local interface, a remote address of a remote interface on at least one remote device to which the local interface connects is received. The initial local address is used to identify the local interfaces assigned to the initial local address in response to receiving a same remote address for each remote interface connected to the local interfaces assigned the initial local address.

Claims

1. A method, comprising:

maintaining an initial configuration assigning multiple local interfaces to one initial local address;

for each local interface, receiving a remote address of a remote interface on at least one remote device to which the local interface connects; and

using the initial local address to identify the local interfaces assigned to the initial local address in response to receiving a same remote address for each remote interface connected to the local interfaces assigned the initial local address.

2. The method of claim 1, further comprising:

generating at least one identifier in response to receiving multiple remote addresses from the remote interfaces connected to the local interfaces; and

assigning different identifiers to the local interfaces previously assigned the initial local address in response to generating the at least one identifier.

3. The method of claim 2, wherein the initial local address comprises a port address of a port to which the local interfaces are assigned as part of the initial configuration.

4. The method of claim 3, wherein each generated identifier comprises an additional port address, further comprising:

configuring an additional port in the device for each generated additional port address; and

assigning local interfaces to the ports, including the additional port and port having the initial local address.

5. The method of claim 4, wherein the local interfaces assigned to one port connect to remote interfaces having a same remote address.

6. The method of claim 2, wherein the at least one received remote address is received as part of an identification sequence, further comprising:

transmitting the initial local address to the remote interfaces connected to the local interfaces.

7. The method of claim 6, wherein the identifiers assigned to the local interfaces, including the at least one generated identifier, comprise local addresses, further comprising:

initiating an additional identification sequence in response to generating the at least one local address; and

transmitting the local addresses identifying the local interfaces to the connected remote interfaces in response to the additional identification sequence.

8-14. -14. (canceled)

15. A device in communication with a plurality of remote interfaces on at least one remote device, comprising:

a plurality of local interfaces;

an initial configuration assigning multiple local interfaces to one initial local address;

circuitry capable of causing operations, the operations comprising;

(i) for each local interface, receiving a remote address of one remote interface to which the local interface connects; and

(ii) using the initial local address to identify the local interfaces assigned to the initial local address in response to receiving a same remote address for each remote interface connected to the local interfaces assigned the initial local address.

16. The device of claim 15, wherein the operations further comprise:

generating at least one identifier in response to receiving multiple remote addresses from the remote interfaces connected to the local interfaces; and

assigning different identifiers to the local interfaces previously assigned the initial local address in response to generating the at least one identifier.

17. The device of claim 16, wherein the initial local address comprises a port address of a port to which the local interfaces are assigned as part of the initial configuration.

18. The device of claim 17, wherein each generated identifier comprises an additional port address, and wherein the operations further comprise:

configuring an additional port in the device for each generated additional port address; and

assigning local interfaces to the ports, including the additional port and port having the initial local address.

19. The device of claim 18, wherein the local interfaces assigned to one port connect to remote interfaces having a same remote address.

20. The device of claim 16, wherein the at least one received remote address is received as part of an identification sequence, wherein the operations further comprise:

transmitting the initial local address to the remote interfaces connected to the local interfaces.

21-31. -31. (canceled)

32. An article of manufacture for interfacing local interfaces in a local device with connected remote interfaces in at least one remote device, wherein the article of manufacture causes operations to be performed, the operations comprising:

maintaining an initial configuration assigning multiple local interfaces to one initial local address;

for each local interface, receiving a remote address of one remote interface to which the local interface connects; and

using the initial local address to identify the local interfaces assigned to the initial local address in response to receiving a same remote address for each remote interface connected to the local interfaces assigned the initial local address.

33. The article of manufacture of claim 32, wherein the operations further comprise:

generating at least one identifier in response to receiving multiple remote addresses from the remote interfaces connected to the local interfaces; and

assigning different identifiers to the local interfaces previously assigned the initial local address in response to generating the at least one identifier.

34. The article of manufacture of claim 33, wherein the initial local address comprises a port address of a port to which the local interfaces are assigned as part of the initial configuration.

35. The article of manufacture of claim 34, wherein each generated identifier comprises an additional port address, wherein the operations further comprise:

configuring an additional port in the device for each generated additional port address; and

assigning local interfaces to the ports, including the additional port and port having the initial local address.

36. The article of manufacture of claim 35, wherein the local interfaces assigned to one port connect to remote interfaces having a same remote address.

37. The article of manufacture of claim 33, wherein the at least one received remote address is received as part of an identification sequence, wherein the operations further comprise:

transmitting the initial local address to the remote interfaces connected to the local interfaces.
