from falling off.
Step 3 Go to the “Pole Mounting” section on page 2-24.
Pole Mounting
The access point can be installed where power is available, without the need for a wired LAN
connection. 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.

What to Do Next
When 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.

Chapter 3 Troubleshooting
Guidelines for Using the Access Points
Guidelines for Using the Access Points
You 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 Notes
Convergence Delays
During 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.

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 Loop
The 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 Server
The 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 Traffic
If 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 List
Before 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.

Using DHCP Option 43
Using DHCP Option 43
You 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. For additional information, refer to the “Configuring
DHCP Option 43” section on page F-1.
Monitoring the Access Point LEDs
If your access point is not working properly, look at the LEDs on the bottom of the unit. You can use
them to quickly assess the unit’s status. Figure 3-1 shows the location of the access point LEDs.
