Methods, systems and computer readable media for wireless device zoning using micro-location data are described.

WiFi device zoning using micro-location data

Methods, systems and computer readable media for securing mDNS in enterprise networks are described. In some implementations, the method can include authorizing one or more service advertisements and validating one or more service advertisements. The method can also include adding one or more information details to a record associated with an advertised service.

Securing mDNS in enterprise networks

One or more implementations can include methods, systems and computer readable media for elastic wireless control planes. In some implementations, the method can include evaluating one or more elastic wireless control plane mode factors, and partitioning each of a plurality of access points into one of an active mode group and a sleep mode group based on the evaluating. The method can also include determining a number of wireless control plane instances needed based on the partitioning. The method can further include activating the number of wireless control plane instances and shutting down any excess wireless control plane instances beyond the number.

Elastic wireless control plane

Embodiments herein include systems and methods for providing a mechanism to enable smooth, seamless, and reliable connectivity for wireless devices in a unified network. The system supports roaming of mobile units across mobility switches. A given mobile unit can retain its IP address in both intra-subnet and inter-subnet roaming scenarios. The given mobile unit also retains its membership to a mobility VLAN to which it had been assigned, even during roaming scenarios. Embodiments include a framework for wireless switches to advertise VLANs they support to peer wireless switches in the mobility domain, and to advertise their capability to act as VLAN servers for those VLANs. Embodiments support VLAN membership management capabilities that allow access points and peer wireless switches to request wireless switches to add VLANs to the tunnels they share.

Method for enabling mobility of client devices in large scale unified networks

One or more implementations can include methods, systems and computer readable media for client location discovery. In some implementations, the method can include receiving, at an access point, a location discovery request message from a client and sending a request from the access point to a location server requesting location information for the client, when a location server is available. The method can also include receiving location information from the location server, when a location server is available and providing the access point location as location information, when a location server is not available. The method can further include sending the location information as a response to the client.

Client location discovery

A mobility network architecture includes a control plane and data plane. The control plane supports notification of VLAN configurations. The data plane supports routing of data amongst VLANs. Each VLAN has an associated identifier value as well as a version number. The version number for a respective VLAN can be updated to a new value each time there is a change to the VLAN. Typically, a controller communicates over the control plane to notify each member switch when a version number has changed for a VLAN. If controller notification fails, a member switch can receive a notification from a neighboring switch that the version number for a VLAN has been modified. In response to detecting such a condition, the switch receiving the notification can prevent forwarding of data even though the switch does not receive notification from the controller that the version number for the VLAN has changed.

Generation and usage of mobility VLAN ID version value

Implementations relate to configuring wireless access points in a wireless network. In some implementations, a method includes selecting, from a plurality of wireless access points in a communication network, a configuring subset of wireless access points and a different compensating subset of wireless access points. New settings are applied to the compensating subset of wireless access points to change a physical coverage of wireless communication provided by the compensating subset, thus at least partially compensating for disabled wireless communication of the configuring subset. The method disables wireless communication provided by the configuring subset, and configures the disabled configuring subset of wireless access points.

Plan-assisted wireless access point configuration

Methods, systems and computer readable media for rogue access point detection are disclosed. In some implementations, the method can include initiating, at one or more processors of a wireless controller, a rogue access point detection process for a wireless network, and transmitting, from the one or more processors, a signature frame to a mobility agent in a wireless switch. The method can also include receiving, at an authorized access point, the signature frame transmitted via a wireless signal from a rogue access point. The method can further include reporting reception of the signature frame to the wireless controller, and generating, at the one or more processors, a signal to shut down a port associated with the rogue access point.

Rogue AP detection

Some implementations can include a method including reserving a range of multicast addresses for handling link-local multicasts and generating a multicast group within the range for each VLAN. The method can also include subscribing at an access point to a corresponding multicast group for a VLAN when a client associates with the access point, and tunneling link local multicast traffic from the client to a WSP component via an access tunnel. The method can further include forwarding the link local multicast traffic from the WSP component to subscribing access points.

Link-local multicast in WLAN deployments

Methods, systems and computer readable media for predictive client VLAN extension are described. In some implementations, the method can include determining client movement within a wireless network domain. The method can also include predicting one or more next hop access points for the client. The method can further include extending a client network to the one or more next hop access points prior to the client roaming to the one or more next hop access points.

Predictive client VLAN extension

Systems, methods and computer readable media for mobility integration with fabric-enabled networks are described. Some implementations can include a method comprising terminating, using one or more processors, an access tunnel at an edge switch of a fabric-enabled network, and establishing, using the one or more processors, a mobility tunnel with the edge switch. The method can also include mapping, using the one or more processors, a mobility network to a service identifier associated with the mobility network. The method can further include forwarding, using the one or more processors, traffic for the mobility network from the edge switch to another edge switch across the fabric enabled network, wherein the traffic includes the service identifier.
