A system for facilitating auto-formation of link aggregations is provided. During operation, the system can obtain information associated with connectivity between a first device and a second device. The system can remotely provide network configurations to the first and second devices via a network. If the connectivity includes a plurality of links, the system can identify a subset of links of the plurality of links that can be configured as a Link Aggregation Group (LAG) based on a set of grouping criteria for selecting a respective link for the LAG. The system can then generate respective configuration commands executable at the first and second devices for generating the LAG based on the information associated with connectivity. Subsequently, the system can send the respective configuration commands to the first and second devices. The configuration commands can facilitate the formation of the LAG at the first and second devices.

Auto-formation of link aggregations based on remotely-issued instructions

Systems, methods, and computer-readable media are described for auto-configuring a network communication port such as an Ethernet port to which a network device is connected in a manner that eliminates or otherwise dramatically mitigates the manual effort required for port configuration, while at the same time, ensuring that network security is maintained by authenticating the device during the auto-configuration process. Various auto-configuration processes are described that include varying levels of verification processing to ensure that the network device connected to the port to be configured is a device that is authorized to connect to the network. In this manner, the threat of device spoofing is eliminated or otherwise substantially reduced. Auto-configuration of network ports in connection with switching a known network device to a new port or connecting a previously unknown network device to a network port are described.

Security-enhanced auto-configuration of network communication ports for cloud-managed devices

A method of authenticating a device management system of a cloud-managed network includes transmitting a first transmission signal, from an access point, to a secondary port of the device management system. The first transmission signal comprises a first request of the access point to connect to the cloud-managed network. When the access point is incompatible with the cloud-managed network, the access point receives a re-direction instruction from the device management system to redirect the access point to a predefined Internet address to provide compatibility data for the access point. The method further includes that in response to receiving the compatibility data, transmitting a second transmission signal to the secondary port that includes a second request to connect to the cloud-managed network. The method include that in response to authentication by the access point, receiving an instruction from the secondary port to connect via a primary port to the cloud-managed network.

Failsafe firmware upgrade for cloud-managed devices

Embodiments are directed to a dynamic radar detection threshold for stateful dynamic frequency selection (DFS). An embodiment of a storage medium includes instructions to operations including estimate a duty time of transmission of wireless signals by an access point, the access point to provide Wi-Fi communication, the wireless signals being communicated on a DFS channel of the access point, adapt, based at least in part on the duty time of transmission, a threshold of radar signals to indicate detection of a radar signal at the access point on the DFS channel, and perform analysis of received wireless signals on the DFS channel at the access point to detect the radar signal using the adapted threshold of radar signals.

Dynamic radar detection threshold for stateful dynamic frequency selection

A network controller may include a memory and a processor. The memory may include instructions executable by the processor to receive a message from an access point. The message may comprise an interference event detected on a particular channel, wherein the particular channel is part of a particular channel list associated with the access point and stored at the network controller in a wireless local area network (WLAN). The memory may further include instructions executable to remove the particular channel from the particular channel list associated with the access point. The memory may further include instructions executable to determine a channel plan for a plurality of access points in the WLAN based on a corresponding plurality of channel lists including the particular channel list and deploy the channel plan to the plurality of access points.

Channel plan determination

A method of authorizing an access point includes receiving a first transmission signal from a first access point. The first transmission signal comprises identifying information of the first access point that includes a first token. The method includes receiving a second transmission signal from a client device. The second transmission signal includes a second token that is received by the client device from an un-provisioned access point. When a match is determined between the first token and the second token, the first access point is identified as the un-provisioned access point. The method includes transmitting the identifying information of the first access point and a request to the client device to authorize the un-provisioned access point. The method includes receiving a third transmission signal from the client device that includes an authorization verification of the un-provisioned access point that authorities the un-provisioned access point to connect to a cloud-managed network.

Bluetooth low energy authorization of cloud-managed devices

An example non-transitory computer readable medium comprising instructions executable by a processor to: determine a channel distribution vector based on a channel priority for a plurality of available wireless channels within a wireless network; receive a set of constraints on a channel plan; determine a channel plan meeting the set of user defined constraints based on the channel distribution vector; and transmit the channel plan to a plurality of radios on the wireless network, wherein the channel plan comprises a channel assigned to each radio of the plurality of radios.

Determine channel plans

A network management system may receive, via a wide area network (WAN), a request to register a pending network device with an entity. The network management system may, in response to receiving the request to register the pending network device with the entity, determine whether the pending network device is able to communicate, via a local area network (LAN) associated with the entity, with a registered network device that is already registered with the entity. The network management system may, in response to at least determining that the pending network device is able to communicate via the LAN with the registered network device, register the pending network device with the entity.

Authorization of cloud-managed network devices

An example access point comprising: a memory; and a processor executing instructions stored in the memory to: determine a first interference event while operating on a first channel, wherein the first channel is designated to the access point in a global channel plan by a network controller based on a global view of a wireless network; switch to operate on a second channel from the first channel for a first amount of time in response to the first interference event; determine a second interference event of the same event type as the first interference event on the first channel, wherein the second interference event is the same event type as the first interference event; and switch to operate on the second channel from the first channel for a longer amount of time than the first amount of time, wherein the second channel is selected based on a local view of the wireless network by the access point.

Channel switching based on interference events

Examples of the present disclosure include: obtain data collected from a plurality of access points (APs) in a WLAN, including a current allocation of channels to radios of the APs according to a current channel plan; calculate a new channel plan which assigns a different channel to at least one of the radios; calculate a first metric that predicts better network performance achieved by the new channel plan than the current allocation of channels to the radios; determine whether the first metric exceeds a first predetermined threshold; and implement the new channel plan in response to determining that the first metric exceeds the first predetermined threshold.

Channel plans for wireless local area networks

An example method comprising: assigning at least one band mode specified in the band mode list to a radio of the identified node, assigning a dual band mode to a set of wireless nodes of the plurality of wireless nodes that each satisfy a baseline coverage when operating on a low frequency band of the wireless band mode, assigning a high frequency band mode to a set of wireless nodes of the plurality of nodes based on band capacity, assigning a channel to the radio of the node on the high frequency band based on a band capacity; and responsive to assigning the channel to the radio on the high frequency band, assigning a channel to each radio of the set of nodes on the low frequency band.

Assign band modes and channels to wireless nodes

A method related to selecting a channel bandwidth may include partitioning the plurality of networks into a plurality (P) of local radio environments and identifying, for the P local radio environments, an available channel bandwidth set comprising a plurality of channel bandwidth values. The method may also relate to determining whether the plurality of channel bandwidth values provide a frequency reuse distance that is greater than a threshold frequency reuse distance, wherein the frequency reuse distance is estimated based at least on the pathloss measurement and, based on a determination that at least one of the plurality of channel bandwidth values provides the frequency reuse distance that is greater than the threshold frequency reuse distance, configuring a channel plan for the plurality of networks with a channel bandwidth value from the at least one of the plurality of channel bandwidth values.
