  • Patent number: 11876800
    Abstract: A device may determine that a first link of the device is active. The device may determine whether a Media Access Control Security (MACsec) session is established on the first link. The device may selectively enable or disable a second link of the device based on determining whether the MACsec session is established on the first link.

  • Patent number: 11811765
    Abstract: A network device may receive a request to access a network from a client device. The network device may determine that the client device is authenticated based on a set of authentication credentials obtained for the client device. The network device may determine, based on the client device being authenticated, that a quantity of devices currently accessing the network using the set of authentication credentials is equal to a maximum quantity of devices permitted to access the network using the set of authentication credentials. The network device may deny the client device access to the network based on the quantity of devices being equal to the maximum quantity of device.

  • Publication number: 20230090356
    Abstract: A network device may obtain information concerning a virtual chassis that indicates that the network device and an additional network device are to be included in the virtual chassis. The network device may determine, based on the information concerning the virtual chassis, that the network device is connected to the additional network device, wherein the network device is connected to the additional network device via a link between a network interface of the network device and a network interface of the additional network device. The network device may cause the network interface of the network device to be converted to a virtual chassis interface and the network interface of the additional network device to be converted to a virtual chassis interface to enable the network device and the additional network device to be included in the virtual chassis to allow bootstrapping of the virtual chassis as a single logical device.

  • Patent number: 11411829
    Abstract: A managing network node may provide, to a bootstrap device, a request for provisioning information to provision the managing network node and one or more managed network nodes, wherein the managing network node and the one or more managed network nodes have an existing relationship, wherein the request comprises a respective identifier for each of the managing network node and the one or more managed network nodes. The managing network node may receive, from the bootstrap device, the provisioning information, wherein the provisioning information includes first provisioning information for the managing network node and respective second provisioning information for each of the one or more managed network nodes. The managing network node may provision the managing network node using the first provisioning information and the one or more managed network nodes using the respective second provisioning information.
