Abstract
A relay device includes a target port coupled to another device; and a processor coupled to the target port and configured to extract identification information on the other device and identification information on a link aggregation group (LAG) configuration applied to the other device, from a frame received through the target port, and determine LAG configuration to be applied to the target port based on the identification information on the other device and the identification information on the LAG configuration applied to the other device.
Claims9
A relay device comprising:
- a port coupled to another device;
- and
- a processor coupled to the port and configured to:
- extract identification information on the other device and identification information on a link aggregation group (LAG) configuration applied to the other device, from a frame received through the port, and
- determine LAG configuration to be applied to the port based on the identification information on the other device and the identification information on the LAG configuration applied to the other device,
- determine whether a first frame has been received through the port,
- transmit a second frame to the other device through the port when it is determined that the first frame has not been received through the port,
- determine whether a loop occurs at the port when a third frame is not received through the port after the second frame is transmitted through the port, and
- apply another LAG configuration to the port when it is determined that the loop occurs at the port.
A method of relaying executed by a processor included in a relay device, the method comprising:
- extracting identification information on another device and identification information on LAG configuration applied to the other device, from a frame received through a port coupled to the other device;
- determining LAG configuration to be applied to the port based on the identification information on the other device and the identification information on the LAG configuration applied to the other device;
- determining whether a first frame has been received through the port;
- transmitting a second frame to the other device through the port when it is determined that the first frame has not been received through the port;
- determining whether a loop occurs at the port when a third frame is not received through the port after the second frame is transmitted through the port;
- and
- applying another LAG configuration to the port when it is determined that the loop occurs at the port.
A non-transitory computer-readable recording medium storing a program that causes a processor included in a relay device to execute a process, the process comprising:
- extracting identification information on another device and identification information on LAG configuration applied to the other device, from a frame received through a port coupled to the other device;
- determining LAG configuration to be applied to the port based on the identification information on the other device and the identification information on the LAG configuration applied to the other device;
- determining whether a first frame has been received through the port;
- transmitting a second frame to the other device through the port when it is determined that the first frame has not been received through the port;
- determining whether a loop occurs at the port when a third frame is not received through the port after the second frame is transmitted through the port;
- and
- applying another LAG configuration to the port when it is determined that the loop occurs at the port.
