A fabric connection assist transceiver device identification system includes a transceiver device having a chassis. A board housed in the chassis includes a networking device connector that is configured to connect to a networking device, a fabric connector that is configured to connect to a fabric, an antenna, and a wireless Electronically Erasable Programmable Read-Only Memory (EEPROM) device that is coupled to the networking device connector and the antenna. The wireless EEPROM device stores first transceiver operating information in at least one first storage element included in the wireless EEPROM device, and provides wireless read access to the first transceiver operating information to a mobile computing device via the antenna when the mobile computing device is positioned a threshold distance from the antenna while the networking device connector is not connected to a networking device.

Fabric connection assist transceiver device identification system

Systems and methods for validating transceivers comprise using a first controller to perform a validation prior to granting a second controller access to the transceiver to communicate in a data plane and, otherwise, restricting the second controller from accessing the transceiver and operating in the data plane to isolate the transceiver from the data plane and protect the second controller from an unqualified or rogue transceiver triggering a recovery procedure, reboot procedure, or similar that otherwise would require manual intervention by technical support personnel and increase equipment downtime and cost.

Transceiver validation ports for network switches

A service platform/transceiver device locking system include a transceiver device that disables its data communication operations during an initialization operation and generates challenge information, and a platform device that retrieves that challenge information. The platform device uses a service platform private key to encrypt the challenge information, and provides the encrypted challenge information and a service-platform-provider-private-key-signed service platform public key to the transceiver device. The transceiver device uses a service platform provider public key to verify a service platform public key in the service-platform-provider-private-key-signed service platform public key to produce a verified service platform public key that it uses to decrypt the encrypted challenge information to produce decrypted challenge information. If the transceiver device determines that the decrypted challenge information matches the challenge information, it enables its data communication operations and locks itself to operate with a service platform associated with the service platform public key.

Service platform/transceiver device locking system

A fabric connection assist system includes a networking device coupled to a fabric management system and a mobile device via a network. The networking device receives fabric connection information for its port from the fabric management system. When the mobile device subsequently identifies that port to the networking device, the networking device identifies fabric connection components to the mobile device that are indicated by the fabric connection information as being supported by its port. When the mobile device subsequently identifies a first of the fabric connection components to the networking device, and the networking device then detects that the first fabric connection component has been connected to its port, the networking device transmits a first fabric connection component confirmation communication to the mobile device that is configured to display a confirmation on the mobile device of the connection of the first fabric connection component to its port.

Fabric connection assist system

A system includes a first device having a first physical layer transceiver (PHY) and a first port that is coupled to the first PHY and that operates in a mode. The system also includes a second device having a second PHY and a second port that is coupled to the second PHY and that operates in a mode. The second device provides, through the second port via a cable coupled to the first port to the first device and prior to advertising the at least one mode that the second port is configured to operate in, a second PHY ability of the second PHY. The second device receives a first PHY ability of the first PHY and determines that a mismatch exists between the first and second PHY abilities. In response to the mismatch, the second device adjusts the operation of the second PHY to correct the mismatch.

PHY ability auto-negotiation system

Aspects of the current patent document include systems and methods to improve configuration of network communication links between devices. In embodiments, a device may attempt auto-negotiation with another device in which transmit power levels are increased in an attempted to establish the link. In embodiments, an approach to establishing a link comprises setting the device in static mode but enabling link training. In yet another embodiment, a hybrid approach to interfaces link up may comprise having auto-negotiation with increasing transmit power attempts enabled by default, followed by static mode link up with link training enabled, in the case the auto-negotiation fails.
