A technique for maintaining network integrity is disclosed. A system according to the technique may include a wired network, a switch, and a wireless access point. The switch can be coupled to the wired network and the wireless access point can be coupled to the switch. The system may further include a forwarding database that stores a mac address for a plurality of devices seen by the switch on the wired network. A method according to the technique may involve detecting identifying information of a device by a wireless access point. The identifying information can be compared with the mac addresses in a forwarding database. If the device is unknown, the unknown device can be classified as rogue and countermeasures can be taken against the rogue device.

System and method for network integrity

A technique for wireless network monitoring involves scanning channels using clients instead of access points. An example of a method according to the technique may include, for example, receiving from a wireless access point a command to perform a channel scanning function, listening on a channel associated with the channel scanning function, and sending RF data found on the channel to the wireless access point. Another example of a method according to the technique may include, for example, scanning a first channel, switching from the first channel to a second channel, sending data on the second channel to an access point, switching from the second channel to the first channel, and resuming scanning on the first channel. A system according to the technique may include one or more scanning clients, proxy clients, multi-channel clients, or other clients that are capable of scanning channels in lieu of an access point.

System and network for wireless network monitoring

A technique for identity based networking is disclosed. A system according to the technique can include a WAN, a first VLAN, a second VLAN, and a network database. The first VLAN and second VLAN can be coupled to the WAN. The network database can include VLAN information. In operation, a client that is authorized on the second VLAN can attempt to connect to the first VLAN. A switch in the WAN can perform a lookup in the network database and determine that the client is authorized on the second VLAN. Based on this information, the client can be connected to the second VLAN using VLAN tunneling.
