The access point uses intelligent wireless routing that is based on the Adaptive Wireless Path Protocol (AWPP). AWPP enables a remote access point to dynamically optimize the best route to the wired LAN network using another access point. The LAP1522 model uses the 5-GHz radio for the Mesh backhaul Mesh connections. The 2.4-GHz radio is used for local wireless client access. The LAP1521 model uses the 2.4-GHz radio for both Mesh backhaul and local wireless client access.To mount your access point on a vertical pole or streetlight pole, you need to install two metal bands around the pole to support the access point. This process requires extra tools and material not provided in the pole mount kit (see Table 2-3).To mount the access point onto a vertical pole or streetlight pole, follow these steps:Step 1 Select a mounting location on the pole to mount the access point. You can attach the access point to any pole from 2 to 16 in. (5.1 to 40.6 cm) in diameter.Note If you will be using a streetlight power tap adapter, position the access point within 3 ft (1 m) of the outdoor light control.Step 2 For poles larger than 3.5 in. (8.9 cm), mount the pole clamp bracket assembly to a pole (see Figure 2-11) using two metal straps. Following the instructions provided with the hand strap tool (AIR-BAND-INST-TL=), loop each metal strap twice through the slots on the strap bracket.Caution Do not place the metal straps in the large open area between the pole clamp bracket and the strap brackets, because this does not properly secure the access point.Ta b l e  2-3 Material Needed to Mount Access Point on a Pole Mounting Method Materials Required In KitVertical or streetlight pole Two 0.75-in.

Step 19 Close the hinged cover (see the “Closing the Access Point Hinged Cover” section on page 2-39).What to Do NextWhen you power up a MAP that is not connected to a wired Ethernet, fiber-optic, or cable network to the controller, the access point uses the Cisco Adaptive Wireless Path Protocol to bind to another MAP with the best path to a RAP connected to the wired network to a controller. The access point sends a discovery request when powered up. If you have configured the access point in the controller correctly, the controller sends back a discovery response to the access point. When that happens, the access point sends out a join request to the controller, and the controller responds with a join confirmation response. Then the access point establishes an LWAPP connection to the controller and gets the shared secret configured on the controller.1Pin length is 0.75 + 0.1in. (1.91 + 0.25 cm).

REVIEW DRAFT—CISCO CONFIDENTIAL3-2Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation GuideOL-12632-03Chapter 3      Troubleshooting  Guidelines for Using the Access PointsGuidelines for Using the Access PointsYou should keep these guidelines in mind when you use the access points:  • The access point can only communicate with controllers and cannot operate independently.   • The access point does not support Wireless Domain Services (WDS) and cannot communicate with WDS devices. However, the controller provides functionality equivalent to WDS when the access point associates to it.  • The access points only supports Layer 3 LWAPP communications with the controllers.In Layer 3 operation, the access point and the controller can be on the same or different subnets. The access point communicates with the controller using standard IP packets. A Layer 3 access point on a different subnet than the controller requires a DHCP server on the access point subnet and a route to the controller. The route to the controller must have destination UDP ports 12222 and 12223 open for LWAPP communications. The route to the primary, secondary, and tertiary controllers must allow IP packet fragments.   • Before deploying your access points, ensure that the following has been done:  –Your controllers are connected to switch ports that are configured as trunk ports.   –Your access points are connected to switch ports that are configured as untagged access ports.   –A DHCP server is reachable by your access points and has been configured with Option 43. Option 43 provides the IP addresses of the management interfaces of your controllers. Typically, a DHCP server can be configured on a Cisco switch.  –Optionally a DNS server can be configured to enable CISCO-LWAPP-CONTROLLER.<local domain> to resolve to the IP address of the management interface of your controller.  –Your controllers are configured and reachable by the access points.  –Your controllers are configured with the access point MAC addresses and the MAC filter list is enabled.  –Your switch must forward DHCP requests.  • The access point PoE-out port should be connected only to a single peripheral customer device, such as a camera or sensor gateway. Cisco recommends that the PoE-out port not be connected to a switch or hub.  • After the access points are associated to the controller, you should change the bridge group name (BGN) from the default value. With the default BGN, the MAPs can potentially try to connect with other mesh networks and slow down the convergence of the network.Important NotesConvergence DelaysDuring deployment, the access points can experience convergence delays due to various causes. The following list identifies some operating conditions that can cause convergence delays:  • A RAP attempts to connect to a controller using any of the wired ports (cable, fiber-optic, PoE-in, or PoE-out). If the wired ports are operational, the RAP can potentially spend several minutes on each port prior to connecting to a controller.
REVIEW DRAFT—CISCO CONFIDENTIAL3-3Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation GuideOL-12632-03Chapter 3      Troubleshooting  Controller MAC Filter List  • If a RAP is unable to connect to a controller over the wired ports, it attempts to connect using the wireless network. This results in additional delays when multiple potential wireless paths are available.  • If a MAP is unable to connect to a RAP using a wireless connection, it then attempts to connect using any available wired port. The access point can potentially spend several minutes for each connection method, before attempting the wireless network again.Bridge LoopThe access point supports packet bridging between wired and wireless network connections. The same network must never be connected to multiple wired ports on an access point or on two bridged access points. A bridge loop causes network routing problems.Controller DHCP ServerThe controller DHCP server only assigns IP addresses to lightweight access points and wireless clients associated to an access point. It does not assign an IP address to other devices, including Ethernet bridging clients on the mesh access points.MAP Data TrafficIf the signal on the access point backhaul channel has a high signal to noise ratio (not good), it is possible for a MAP to connect to the controller but not be able to pass data traffic, such as pinging the access point. This can occur because the default datarate for backhaul control packets is set to 6 Mbps, but the default datarate for data traffic is 24 Mbps. Controller MAC Filter ListBefore activating your access point, you must ensure that the access point MAC address has been added to the controller MAC filter list and that Mac Filter List is enabled.Note The access point MAC address and barcode is located on the bottom of the unit. When two MAC addresses are shown, use the top MAC address.To view the MAC addresses added to the controller MAC filter list, you can use the controller CLI or the controller GUI:  • Controller CLI—Use the show macfilter summary controller CLI command to view the MAC addresses added to the controller filter list.  • Controller GUI—Log into your controller web interface using a web browser, and choose SECURITY > AAA > MAC Filtering to view the MAC addresses added to the controller filter list.
REVIEW DRAFT—CISCO CONFIDENTIAL3-4Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation GuideOL-12632-03Chapter 3      Troubleshooting  Using DHCP Option 43Using DHCP Option 43You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling the access point to find and join a controller. Refer to the product documentation for your DHCP server for instructions on configuring DHCP Option 43.
