Interpreting LAP LEDs − LAP1130
Q. What is the difference between Roof−top Access Points (RAPs) and
Pole−top Access Points (PAPs) as modes of lightweight Mesh Access
Points (MAPs)?
A. These are the modes that the outdoor MAPs can operate as part of the mesh network. The
mesh networking solution, which is part of the Cisco Unified Wireless Network Solution,
enables two or more Cisco Aironet Lightweight MAPs to communicate with each other over
one or more wireless hops to join multiple LANs or to extend 802.11b wireless coverage.
These access points are used as part of the mesh network and operate in two modes:
RAP
1. 
PAP
2. 
RAPCisco MAPs that operate in RAP mode are the parent node to any bridging or mesh
network and connect a bridge or mesh network to the wired network. Therefore, there can
only be one RAP for any bridged or mesh network segment. In a mesh network, Cisco MAPs
are configured, monitored, and operated from and through any Cisco WLAN controller
(WLC) deployed. Any MAP that has the wired connection to the WLC assumes the role of
RAP. This RAP uses the backhaul wireless interface to communicate with neighboring PAPs.
PAPCisco MAPs that operate in PAP mode have no wired connection to a Cisco WLC.
They can be completely wireless and support clients that communicate with other PAPs or
RAPs, or they can be used to connect to peripheral devices or a wired network. The Ethernet
port is disabled by default for security reasons, but you should enable it for PAPs.
Refer the Zero Touch Configuration section of the Cisco Mesh Networking Solution
Deployment Guide for more information on how a MAP assumes the role of RAP and PAP.
Q. How do you interpret the radiation pattern of the 1000 Series
Lightweight Access Point (LAP) Antennas?
A. Azimuth diagrams are usually with the device/antenna in normal operating orientation
(vertical, top up, in the center of the diagram for omni; horizontal, mount at the center,
forward direction towards "0" on the diagram). The A side is most likely forward and
represented at the 0 mark for azimuth, and the 90 mark for elevation. The B side is
represented at the 180 mark for azimuth, and 270 for elevation. The pattern does not change
in free−space if the unit is inverted. But the immediate surfaces can cause
reflection/absorbtion and can alter the pattern. Metallic objects near the radiators (within ~2
wavelengths or so) can also distort the pattern significantly. The Cisco Aironet Antenna
Reference Guide has more information. The 1000 Series Antennas are explained in the last
section of the document.
Q. Can we restrict which APs join a controller? I see the
SECURITY/AAA/AP Policies page, where you can authorize APs against
the AAA or certificate. I am able to add an AP to the Authorization List,
but do these things restrict only my Authorization list of APs to join the
controller?
A. No, controllers handle APs on a first come, first serve basis. You possibly can play with
