What is CAPWAP process?

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.

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.

How is a CAPWAP tunnel formed?

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.

What is Cisco CAPWAP controller?

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 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.

Is CAPWAP better than Lwapp?

Key Point: –> Control Provisioning of Wireless Access Points is a standard protocol that enables a wireless LAN controller to manage access points. –> CAPWAP is based upon Light Weight Access Point Protocol. –> CAPWAP does not support layer 2 mode compared to LWAPP. –> CAPWAP is more secure to LWAPP.

What is the expansion for CAPWAP?

Control and Provisioning of Wireless Access Points
CAPWAP (Control and Provisioning of Wireless Access Points) 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 is difference between CAPWAP and Lwapp?

The only difference is the protocol being used between the AP and the controller. DTLS is used as a tightly integrated secure wrapper for a CAPWAP packet….Differences from LWAPP.

Feature	LWAPP	CAPWAP
L2 mode support	Yes	No
Security	AES-CCMP	AES-CCMP with DTLS protocol
Control plane encryption	Yes	Yes

What is DTLS and CAPWAP?

DTLS is a standards-track Internet Engineering Task Force (IETF) protocol based on TLS. CAPWAP control packets are management packets exchanged between a controller and an access point while CAPWAP data packets encapsulate forwarded wireless frames.

Is CAPWAP a TCP?

CAPWAP sessions use UDP for both the control and data channels, as follows: CAPWAP Control Channel: Uses UDP port 5246.
