What is LWAPP and CAPWAP?

What is LWAPP and CAPWAP?

CAPWAP is an abbreviation for Control and Provisioning of Wireless Access Points protocol (CAPWAP), which is based on LWAPP, which is a standard, interoperable protocol that enables a controller to manage a collection of wireless access points.

What is the purpose of CAPWAP?

CAPWAP (Control and Provisioning of Wireless Access Points) is a protocol that enables an access controller (AC) to manage a collection of wireless termination points.

What protocol does CAPWAP use?

Protocol overview CAPWAP is based on Lightweight Access Point Protocol (LWAPP). The state machine of CAPWAP is similar to LWAPP’s, but with the addition of a full Datagram Transport Layer Security (DTLS) tunnel establishment.

Is CAPWAP a TCP or UDP?

CAPWAP sessions use UDP for both the control and data channels, as follows: CAPWAP Control Channel: Uses UDP port 5246. CAPWAP Data Channel: Uses UDP port 5247 and encapsulates (tunnels) the client’s 802.11 frames.

What advantage does the CAPWAP protocol have over LWAPP?

Second, the CAPWAP discovery process is much more robust than LWAPP. Third, dynamic MTU is part of CAPWAP. This allows for better communication between the controller and the network. This was a big issue with LWAPP and a much needed improvement.

What is LWAPP Cisco?

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.

Is CAPWAP encrypted?

CAPWAP Communication: Control and Data Encryption (Cisco Wireless LAN Controllers) After the DTLS session is established, CAPWAP control traffic is encrypted and CAPWAP data traffic can be encrypted.

Is Cisco CAPWAP encrypted?

Information About Data Encryption The controller enables you to encrypt Control and Provisioning of Wireless Access Points (CAPWAP) control packets (and optionally, CAPWAP data packets) that are sent between the access point and the controller using DTLS.

Is LWAPP Cisco proprietary?

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

What are LWAPP packets?

LWAP provides the control messaging protocol and data encapsulation….Lightweight Access Point Protocol LWAPP

• The wireless client sends a packet to the wireless access point.
• The wireless access point decrypts the packet and encapsulates it with an LWAPP header, forwarding it to the WLC.

Which device uses the LWAPP and CAPWAP protocols for communication?

Which device uses the LWAPP and CAPWAP protocols for communication? Explanation: A Wireless Lan Controller (WLC) unitizes Lightweight Access Point Protocol (LWAPP) and Wireless Access Points (CAPWAP) Protocols. A WLC is a centralized point that allows a network administrator to manage a number of access points (APs).

Where is LWAPP used?

In the Cisco Unified Wireless Architecture, a wireless LAN controller (WLC) is used to manage the wireless access point configuration and firmware creating an LWAPP tunnel. LWAP provides the control messaging protocol and data encapsulation.

What is Lwapp Cisco?

What is Dtls and CAPWAP?

Data Datagram Transport Layer Security (DTLS) enables you to encrypt CAPWAP data packets that are sent between an access point and the controller using DTLS, which is a standards-track IETF protocol that can encrypt both control and data packets based on TLS.

What UDP ports and IP protocols is not used by CAPWAP for IPv4?

IPv4 and IPv6 can use UDP ports 5246 and 5247. However, CAPWAP tunnels use different IP protocols in the frame header. IPv4 uses IP protocol 17 and IPv6 uses IP protocol 136.

What is the LWAPP in cyber security?

LWAPP is a communications protocol for networks that are migrating to “thin” access-point technology. Traditional WLAN products push all traffic handling, authentication, radio frequency management and mobility functions out to individual “fat” access points.

How does CAPWAP tunnel work?

When the AP joins a WLC, a Control and Provisioning of Wireless Access Points protocol (CAPWAP) tunnel is formed between the two i.e. WLC and AP. All traffic generated from users is sent through the CAPWAP tunnel. It is not supported in layer 2 mode unlike LWAPP which is supported in both Layer 2 and Layer 3 mode.

Is CAPWAP a Layer 2 or Layer 3?

CAPWAP communications between the controller and lightweight access points are conducted only at Network Layer 3. Layer 2 mode is not supported in CAPWAP.

What is DTLS encryption?

Datagram Transport Layer Security (DTLS) is a communications protocol designed to protect data privacy and preventing eavesdropping and tampering. It is based on the Transport Layer Security (TLS) protocol, which is a protocol that provides security to computer-based communications networks.
