What protocol is used between APs and WLC?

Control and Provisioning of Wireless Access Points (CAPWAP) is a standard and interoperable protocol that enables a Wireless LAN Controller (WLC) to manage access points (AP) or wireless termination points (WTP).

What is WLC in access point?

A wireless LAN controller (WLC) is a network component that manages wireless network access points and allows wireless devices to connect to the network. It offers central control over network elements, increases network visibility, and greatly simplifies individual component monitoring.

What is WLC and AP in networking?

A Wireless LAN Controller (WLC) gives the network administrators the ability to see all the data and information linked to the network. They are able to observe on the device the hardware status, the situation of the physical ports, and a summary of the Access Points (APs) connected anytime they want.

Do you need a controller for multiple access points?

A UniFi Controller isn’t needed to run those APs, but it provides most of the benefits of going with UniFi. It lets you change all your settings and monitor your network. If you get the UDM or UDM-Pro, you’ll also be able to use it to control your networks, routing, and firewall settings.

Why do I need a wireless controller?

Similar to an amplifier in a stereo system, the wireless controller allows devices from farther distances to connect. Besides, it enables the network administrators to check all the data related to the network and is able to detect rogue access points and recent traps generated by the access points.

Can a WLC act as a DHCP server?

Cisco WLC supports two modes of DHCP operations in case an external DHCP server is used, DHCP proxy mode and DHCP bridging mode. The DHCP proxy mode serves as a DHCP helper function to achieve better security and control over DHCP transaction between the DHCP server and the wireless clients.

How does Cisco WLC works?

The WLC takes the bandwidth produced by your router and stretches it to fit the needs of your network. Much like an amplifier for a stereo system, it boosts the signal of the router to allow devices from farther distances to still be able to connect.

What is the service port on a WLC used for?

The service port is used for out-of-band management of the controller and system recovery and maintenance in the event of a network failure. It is important to note that the service port does not support VLAN trunking or VLAN tagging and is therefore required to connect to an access port on the switch.
