Abstract
A link validation system includes a first device and a second device. The first device identifies that a first link to the second device has become available via a first port on the first device, and determines that the first link to the second device is not a valid link. In response to determining that the first link to the second device is not a valid link, the first device configures the first port in an auto-negotiation error state. Subsequent to configuring the first port in the auto-negotiation error state, the first device detects a port connection cycling operation associated with the first port and, in response, clears the auto-negotiation error state for the first port.
Claims20
A link validation system, comprising:
- a second device;
- and
- a first device that is configured to:
- identify that a first link to the second device has become available via a first port on the first device;
- determine that the first link to the second device is not a valid link;
- configure, in response to determining that the first link to the second device is not a valid link, the first port in an auto-negotiation error state;
- detect, subsequent to configuring the first port in the auto-negotiation error state, a port connection cycling operation associated with the first port;
- and
- clear, in response to detecting the port connection cycling operation associated with the first port, the auto-negotiation error state for the first port.
An Information Handling System (IHS), comprising:
- a processing system;
- and
- a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a link validation engine that is configured to:
- identify that a first link to a device has become available via a first port coupled to the processing system;
- determine that the first link to the device is not a valid link;
- configure, in response to determining that the first link to the device is not a valid link, the first port in an auto-negotiation error state;
- detect, subsequent to configuring the first port in the auto-negotiation error state, a port connection cycling operation associated with the first port;
- and
- clear, in response to detecting the port connection cycling operation associated with the first port, the auto-negotiation error state for the first port.
A method for validating a link, comprising:
- identifying, by a first device, that a first link to a second device has become available via a first port on the first device;
- determining that the first link to the second device is not a valid link;
- configure, in response to determining that the first link to the second device is not a valid link, the first port in an auto-negotiation error state;
- detecting, subsequent to configuring the first port in the auto-negotiation error state, a port connection cycling operation associated with the first port;
- and
- clearing, in response to detecting the port connection cycling operation associated with the first port, the auto-negotiation error state for the first port.
