  • Patent number: 11757722
    Abstract: A switching fabric role assignment system includes a plurality of switch devices coupled together in a switching fabric. A first switch device included in the plurality of switch devices receives an endhost device identification communication from an endhost device when the endhost device is connected to the first switch device. The first switch device uses the endhost device identification communication to identify an endhost device type of the endhost device and determines, based on the endhost device type, a first switch device role for the first switch device. The first switch device then transmits a first switch device role communication that identifies the first switch device role to a second switch device included in the plurality of switch devices and connected to the first switch device. The second switch device may then determine, based on the first switch device role, a second switch device role for the second switch device.

  • Patent number: 10764213
    Abstract: A switching fabric loop prevention system includes first slave switch devices in a switching fabric that each automatically determine a first slave switch device role for themselves based on first directly connected device identification information received from a first directly connected device, and second slave switch devices in the switching fabric that each automatically determine a second slave switch device role for themselves based on second directly connected device identification information received from a second directly connected device. A master switch device in the switching fabric then configures each of the first slave switch devices having the first slave switch device role to prevent first type communications that have been received from one of the second slave switch devices having the second slave switch device role from being forwarded to another of the second slave switch devices having the second slave switch device role.

  • Publication number: 20200252336
    Abstract: A switching fabric configuration and management system includes switch devices. Each of the switch devices identifies a domain in a switching fabric database in that switch device, and determines others of the switch devices that share the domain. Each of the switch devices may then communicate with the others of the switch devices that share the domain to designate a master switch device and one or more slave switch devices from the switch devices that share the domain. The designation of the master switch device and the one or more slave switch devices configures the master switch device and the one or more slave switch devices as a switching fabric. Each slave switch devices then reports their slave switch device status to the master switch device, and the master switch device performs at least one control operation on the at least one slave switch device.
