Chapter 7 Controlling Lightweight Access Points

Cisco Aironet 1510 Series Lightweight Outdoor Mesh Access Points

It is a self-contained outdoor unit that can be configured with a wired backhaul connection to an Ethernet

segment for a rooftop deployment or with a wireless backhaul for a pole-top deployment. The AP1510

can be installed anywhere power is available, without the need for a network connection. Using the Cisco

Adaptive Wireless Path Protocol (AWPP), the AP1510 is able to dynamically optimize the best route to

the connected network within the mesh.

The AP1510 operates with controllers to provide centralized and scalable management, high security,

and mobility. Designed to support zero-configuration deployments, the AP1510 easily and securely joins

the mesh network and is available to manage and monitor the network through the controller GUI or CLI.

The AP1510 is equipped with two simultaneously operating radios: a 2.4-GHz radio used for client

access and a 5-GHz radio used for data backhaul to other AP1510s. A wide variety of antennas are

available that provide flexibility when deploying the AP1510 over various terrains. Wireless LAN client

traffic passes through the access point’s backhaul radio or is relayed through other AP1510s until it

reaches the controller Ethernet connection.

Note For more information on the AP1510, refer to the quick start guide and hardware installation guide for

this access point. You can find these documents at this URL:

Wireless Mesh

In a wireless mesh deployment (see Figure 7-3), multiple AP1510s are deployed as part of the same

network. One or more AP1510s have a wired connection to the controller and are designated as root

access points (RAPs). Other AP1510s that relay their wireless connections to connect to the controller

are called mesh access points (MAPs). The MAPs use the AWPP protocol to determine the best path

through the other AP1510s to the controller. The possible paths between the MAPs and RAPs form the

wireless mesh that is used to carry traffic from wireless LAN clients connected to MAPs and to carry

traffic from devices connected to MAP Ethernet ports.

The mesh network can carry two types of traffic simultaneously: wireless LAN client traffic and MAP

bridge traffic. Wireless LAN client traffic terminates on the controller, and MAP bridge traffic

terminates on the Ethernet ports of the AP1510s. You need to keep in mind three important concepts

when considering the configuration of a mesh network:

• Sector—A collection of mesh access points connected together by the AWPP and through a single

RAP to the controller.

• Network—A collection of sectors that cover a proximate geographic area.

• Controller subnet service set—A collection of controllers on a subnet servicing one or more

sectors.

Membership in the mesh network is controlled in a variety of ways:

• Each AP1510 MAC address must be entered into the MAC filter list database to ensure that the

access points are authorized to use the controller. Each controller to which the access point may

connect must have its MAC address entered into the database.

The MAC filter list works in conjunction with the certificate that is stored in the access point’s

nonvolatile memory to provide strong security for access points connecting to the network. As such,

the MAC filter list is required for mesh access points to be able to connect to the controller.
