AP region management	Supports three AP region deployment modes: ·Distributed deployment: APs are deployed independently. An AP is equivalent to a region and does not interfere with other APs. APs work at the maximum power and do not perform radio calibration. ·Common deployment: APs are loosely deployed. The transmit power of each radio is less than 50% of the maximum transmit power. ·Centralized deployment: APs are densely deployed. The transmit power of each radio is less than 25% of the maximum transmit power. Specifies the default region to which automatically discovered APs are added.
AP profile management	Specifies the default AP profile that is applied to automatically discovered APs.

Application Scenarios

The AC6605-26-PWR is connected to an aggregation switch in chain or branched mode.

The AC6605-26-PWR processes both control flows and data flows. Management flows must be transmitted over Control And Provisioning of Wireless Access Points (CAPWAP) tunnels. Data flows can be transmitted over CAPWAP tunnels or not, as required.

The CAPWAP protocol defines how APs communicate with ACs and provides a general encapsulation and transmission mechanism for communication between APs and ACs. CAPWAP defines data tunnels and control tunnels.

Data tunnels encapsulate 802.11 data packets to be sent to the AC.

Control tunnels transmit control flows for remote AP configuration and WLAN management.

Two forwarding modes are available according to whether data flows are transmitted on CAPWAP tunnels:

Direct forwarding: is also called local or distributed forwarding.

Tunnel forwarding: is also called centralized forwarding. It is usually used to control wireless user traffic in a centralized manner.

You can select the chain or branched mode according to networking requirements. On the AC, you can configure direct forwarding for some APs and tunnel forwarding for other APs. In tunnel forwarding mode, all wireless user traffic is aggregated to an AC, which may create a switching bottleneck. Therefore, tunnel forwarding is seldom used on enterprise networks.
