Configuration of communication interfaces for link aggregation

A communications device comprising:

• physical communication interfaces;
• processing circuitry;
• and
• a non-transitory machine-readable medium comprising instructions that, when executed by the processing circuitry, cause the communications device to:
• whenever one of the physical communications interfaces is newly connected to a peer device to which any other of the physical communications interfaces are already connected, automatically and independently of receipt of any link aggregation packet:
• configure each one of the physical communications interfaces that is connected to the respective peer device for aggregation into a same link aggregation group;
• and
• whenever one of the physical communications interfaces is newly disconnected from a peer device to which exactly one other of the physical communications interfaces is connected, automatically:
• configure both the one of the physical communications interfaces and the exactly one other of the physical communications interfaces for removal from a link aggregation group that comprises those of the physical communications interfaces that are connected to the respective peer device.

A non-transitory computer readable medium comprising instructions that, when executed by a processor of a communications device, cause the communications device to:

• monitor physical communications interfaces of the communications device for connections to peer devices;
• in response to detecting, independently of receipt of any link aggregation packet, that at least two of the physical communications interfaces are connected to a same peer device as one another, automatically configure the at least two of the physical communications interfaces for aggregation into a same link aggregation group as one another;
• and
• in response to detecting that one of the physical communications interfaces has disconnected from a peer device to which it was previously connected, automatically configuring the one of the physical communications interfaces for removal from a link aggregation group comprising those of the physical communications interfaces that are connected to the respective peer device.
