What Is the Function of a WLAN AC Source or CAPWAP Source?
As a network element, an AC must be configured with an IP address for communication with other devices. The WLAN AC Source or CAPWAP Source parameter is used to assign an IP address to the AC. Generally, the IP address of the loopback interface or VLANIF interface serves as the AC source.
In versions earlier than V200R005C00, WLAN AC Source is used. In V200R005C00 and later versions, WLAN AC Source is changed to CAPWAP Source.
