CAPWAP Data
CAPWAP Data on port 5247 facilitates the management and provisioning of wireless access points by carrying encapsulated wireless data packets between controllers and APs. Defined by RFC 5415, it separates data from control traffic (usually on port 5246) to maintain efficient wireless network operations, enabling scalability, flexibility, and simplified management..
The Control And Provisioning of Wireless Access Points (CAPWAP) protocol, defined in RFC 5415, standardizes the communication between Wireless LAN Controllers (WLCs) and lightweight Access Points (APs). Port 5247 is primarily used for CAPWAP Data messages, carrying user wireless data between APs and controllers across a secure and manageable tunnel, distinct from control traffic typically on port 5246.
CAPWAP operates by encapsulating IEEE 802.11 frames within UDP packets, allowing centralized management of multiple APs without requiring full routing capabilities on each AP. By centralizing control, network administrators can more effectively deploy firmware updates, enforce security policies, and manage network congestion.
Typically, CAPWAP data tunnels streamline wireless network architectures in enterprise environments by separating management/control and data planes, thus improving scalability and supporting rapid access point deployment. This separation aids in reducing latency for end-user data and improves reliability.
