How does WLC work?

Access points, called Lightweight Access Points (LAPs) in the unified environment, register themselves with a WLC and tunnel all the management and data packets to the WLCs, which then switch the packets between wireless clients and the wired portion of the network. All the configurations are done on the WLC.
A.

What is a wireless access point controller?

A thin AP is simply an access point that is managed by a WLAN controller. The WLAN controller provides the thin AP its configuration and also functions as a switch for all the wireless traffic. The WLAN controller also consolidated management for the entire wireless network in one place.
  • What is the wireless controller?

    A wireless LAN (WLAN) controller is used in combination with the Lightweight Access Point Protocol (LWAPP) to manage light-weight access points in large quantities by the network administrator or network operations center. The wireless LAN controller is part of the Data Plane within the Cisco Wireless Model.
  • What is a cluster access point?

    The AP cluster is a dynamic, configuration-aware group of APs in the same subnet of a network. The cluster provides a single point of administration and enables you to view the deployment of access points as a single wireless network rather than a series of separate wireless devices.
  • What is an autonomous access point?

    In the Cisco Unified Wireless LAN architecture, wireless devices operate in the lightweight mode using Lightweight Access Point Protocol (LWAPP), (as opposed to autonomous mode). The lightweight access point, or wireless device, has no configuration until it associates to a controller.
B.

What does Capwap do in a controller based wireless system?

The Control And Provisioning of Wireless Access Points (CAPWAP) protocol is a standard, interoperable networking protocol that enables a central wireless LAN Access Controller (AC) to manage a collection of Wireless Termination Points (WTPs), more commonly known as Wireless Access Points.
  • What is Cisco wireless controller?

    A wireless LAN (WLAN) controller is used in combination with the Lightweight Access Point Protocol (LWAPP) to manage light-weight access points in large quantities by the network administrator or network operations center. The wireless LAN controller is part of the Data Plane within the Cisco Wireless Model.
  • What is a network bridge?

    A network bridge is a computer networking device that creates a single aggregate network from multiple communication networks or network segments. This function is called network bridging. Bridging is distinct from routing.
  • What is the difference between a router and a bridge?

    A bridge is a product that connects a local area network (LAN) to another local area network that uses the same protocol (for example, Ethernet or Token Ring). A router is often included as part of a network switch. Note: Learn more about the difference between a bridge and a switch in this expert Q/A.
C.

What is a controller in networks?

A network interface controller (NIC, also known as a network interface card, network adapter, LAN adapter or physical network interface, and by similar terms) is a computer hardware component that connects a computer to a computer network.
  • What is the use of controller in Angularjs?

    A controller is defined using ng-controller directive. A controller is a JavaScript object containing attributes/properties and functions. Each controller accepts $scope as a parameter which refers to the application/module that controller is to control.
  • What is a controller in process control?

    Closed-loop control is used to achieve this. The process controller looks at a signal representing the process value, compares it to the desired setpoint and acts on the process to minimize the difference (error). The method used by the controller to correct the error is the control mode.
  • What is the wireless controller?

    A wireless LAN (WLAN) controller is used in combination with the Lightweight Access Point Protocol (LWAPP) to manage light-weight access points in large quantities by the network administrator or network operations center. The wireless LAN controller is part of the Data Plane within the Cisco Wireless Model.
