What does a WLAN controller do?

A wireless LAN (or 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 does LWAPP stand for?

LWAPP. Light Weight Access Point Protocol.

Why would an organization use CAPWAP?

The IETF developed CAPWAP with three goals in mind: to centralize authentication and policy enforcement functions in wireless networks, to shift higher-level protocol processing away from access points and to provide an extensible protocol that could be used with various types of access points (APs).

What is a CAPWAP connection?

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 a root access point?

A root access point is a mesh-capable access point that is set up with a wired connection to your network and provides Internet connectivity to the extender access point. Each root can support up to 4 extenders. The extenders connect to the root in a star topology only.

What is the benefit of lightweight wireless access points?

Lightweight Access Point Protocol (LWAPP) is the name of a protocol that can control multiple Wi-Fi wireless access points at once. This can reduce the amount of time spent on configuring, monitoring or troubleshooting a large network. The system will also allow network administrators to closely analyze the network.

What is CAPWAP process?

Is CAPWAP encrypted?

The CAPWAP control traffic is always encrypted but the user traffic is only encrypted if the controller is a 5508. This is because of the additional resources available with the 5508 to be able to handle the additional overhead from the encryption.

Is LWAPP Cisco proprietary?

LWAPP is Cisco’s proprietary protocol used to provide central control of Access Points.

What is CAPWAP preferred mode?

Prefer-mode allows an administrator to configure CAPWAP L3 transport (IPv4 and IPv6) through which access points join the WLC (based on its primary/secondary/tertiary configuration). There are two levels of prefer-mode. • AP Group specific. • Global Configuration. Guidelines for Configuring Preferred Mode.

What is computer network controller?

A controller, in a computing context, is a hardware device or a software program that manages or directs the flow of data between two entities. In computing, controllers may be cards, microchips or separate hardware devices for the control of a peripheral device.

What is network controlling devices?

Hardware devices that are used to connect computers, printers, fax machines and other electronic devices to a network are called network devices. These devices transfer data in a fast, secure and correct way over same or different networks.

What is the difference between an access point and a bridge?

The distinction is important: A wireless access point connects users to a network by creating a wireless signal they can use. A bridge, in contrast, connects separate networks —your preexisting wireless home network to all of the devices connected to the bridge.

What is LWAPP and how does it work?

Lightweight Access Point Protocol ( LWAPP) is the name of a protocol that can control multiple Wi-Fi wireless access points at once. This can reduce the amount of time spent on configuring, monitoring or troubleshooting a large network. The system will also allow network administrators to closely analyze the network.

What is CAPWAP and how does it work?

What is CAPWAP? CAPWAP is an abbreviation for Control and Provisioning of Wireless Access Points and interoperable protocol that enables a Wireless LAN Controller (WLC) to manage access points (AP) or wireless termination points (WTP). CAPWAP is based on the Lightweight Access Point Protocol (LWAPP).

What is the difference between CAPWAP and LWAPP protocols?

What does clear LWAPP private CONFIG DEBUG AP do?

Clear Access Point Commands clear lwapp private-config debug ap show stats video transfer upload peer-start The Cisco Wireless LAN solution command-line interface (CLI) enables operators to connect an ASCII console to the Cisco Wireless LAN Controller and configure the controller and its associated access points.
