From the wireless LAN controller, a lightweight access point can be configured to operate in several different types of mode: Local The default mode of a lightweight access point. It offers one or more basic service sets on a specific channel. When the access point is not transmitting it scans the other channels to measure…

When an AP has completed the staging process and joined a wireless LAN controller, it needs to maintain the connection to the wireless LAN controller to remain functional. If the wireless LAN controller fails, it could mean dozens of access points may drop off the the network, likewise if a group of access points lose…

After the discovery process of a lightweight access point; it should of built a list of live wireless LAN controllers that it can communicate with. The lightweight access point begins a separate process of selecting a single wireless LAN controller and sending a CAPWAP Join Request to it. The access point will wait until the…

Once the lightweight Cisco access point starts up, it operates in a number of different states before it becomes a functional basic service set (BSS). Each of these possible states are defined as part of the Control and Provisioning of Wireless Access Points (CAPWAP) specification in a process called a state machine. Access Point Boots…

For a Cisco Lightweight Access Point to function, it must connect to a Cisco Wireless LAN controller. The access point must discover the wireless LAN controller and bind itself to it in order to function. A Cisco lightweight access point is designed to be ‘touch-free’; meaning it can be unboxed and connected to the wired…

In lightweight mode, a Cisco access point can’t provide a working BSS for wireless users. In order for a Cisco wireless access point in lightweight mode to become functional, it must join a Cisco Wireless LAN Controller to become active. This dependency on a Cisco WLC is known as a split-MAC architecture: The access point…

An autonomous access point is self contained offering a fully functional basic service set (BSS). They are a natural extension to a switched network and can offer wireless service set identifiers (SSID) to connect to wired virtual local area networks (VLANs) at the access layer. The autonomous access point provides a short and simple path…

Cisco Wireless Access Points can operate in two modes, autonomous or lighweight. The mode that a Cisco Wireless Access Point operates in depends on the software image that has been installed onto the device. Autonomous access points are self-sufficient and standalone, but lightweight access points rely on a controller device to operate sufficiently.

The basic RF signal is known as a carrier signal, it is used to carry useful information. In terms of wireless, a wireless LAN signal carries data. To add this data to the wireless carrier signal, the frequency of the original carrier signal must be preserved but some altering occurring to signify a 1 or…

With a wired link, a electrical signal is applied at one end and carried to the other end. This is simple for the wire as it’s continuous and conductive. There is no wire for a wireless link, so it is not as continuous or conductive. A wireless link send signals in a steady up and…
