Guidelines for Using a Lightweight Access Point/Bridge

Lightweight Access Point

The lightweight access point (model: AIR-LAP1310G) is part of the Cisco Integrated Wireless Network Solution and requires no manual configuration before they are mounted. The lightweight access point is automatically configured by a Cisco wreless LAN controller (hereafter called a controller) using the Lightweight Access Point Protocol (LWAPP).

The lightweight access points contain one integrated radio: a 2.4-GHz radio (IEEE 802.11g). Using a controller, you can configure the radio settings.

In the Cisco Centralized Wireless LAN architecture, access points operate in the lightweight mode (as opposed to autonomous mode). The lightweight access points associate to a controller. The controller manages the configuration, firmware, and controls transactions such as 802.1x authentication. In addition, all wireless traffic is tunneled through the controller.

LWAPP is an Internet Engineering Task Force (IETF) draft protocol that defines the control messaging for setup and path authentication and run-time operations. LWAPP also defines the tunneling mechanism for data traffic.

In an LWAPP environment, a lightweight access point discovers a controller by using LWAPP discovery mechanisms and then sends it an LWAPP join request. The controller sends the lightweight access point an LWAPP join response allowing the access point to associate with the controller. When the lightweight access point is associated, it downloads its software if the versions on the lightweight access point and controller do not match. After a lightweight access point associates with a controller, you can reassign it to any controller on your network.

LWAPP secures the control communication between the lightweight access point and controller by means of a secure key distribution, using X.509 certificates on both the lightweight access point and controller.

Guidelines for Using a Lightweight Access Point/Bridge

You should keep these guidelines in mind when you use a lightweight access point/bridge:

•A lightweight access points/bridge can communicate only with Cisco 2006 series wireless LAN controllers or 4400 series controllers. Cisco 4100 series, Airespace 4012 series, and Airespace 4024 series controllers are not supported because they lack the memory required to support access points running Cisco IOS software.

•A lightweight access points/bridge 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.

•A lightweight access points/bridge supports eight BSSIDs per radio and a total of eight wireless LANs per access point. When a lightweight access point associates to a controller, only wireless LANs with IDs 1 through 8 are pushed to the access point.

•A lightweight access points/bridge does not support Layer 2 LWAPP. They must get an IP address and discover the controller using DHCP, DNS, or IP subnet broadcast.

•The lightweight access point console port is enabled for monitoring and debuging purposes (all configuration commands are disabled when the access point is associated to a controller).

1300 specifications

Cisco Systems 1300 series, commonly referred to as the Cisco Aironet 1300 Series, represents a pivotal advancement in wireless networking solutions designed for outdoor environments. These access points are primarily intended for outdoor wireless applications, including temporary installations, public areas, and enterprises requiring robust outdoor coverage.

One of the standout features of the Cisco 1300 series is its ruggedized design. The access points are built to withstand harsh weather conditions, including extreme temperatures and precipitation. They comply with IP67 ratings, ensuring protection against dust and water intrusion, making them suitable for deployment in various environmental conditions.

The Cisco 1300 series provides comprehensive WLAN coverage through its support for various wireless standards, including 802.11b, 802.11g, and 802.11n. This compatibility ensures interoperability with existing wireless infrastructure while enabling faster data rates and improved connectivity. The technology leveraged in the Cisco 1300 series offers enhanced throughput and capacity, ensuring seamless connectivity for end-users.

Another key characteristic is the integration of advanced security features. The access points support robust encryption protocols, such as WPA2 and 802.1X, safeguarding sensitive data transmitted over the air. The ability to create secure guest access networks also enhances security, allowing organizations to provide internet access without compromising internal network safety.

Cisco's proprietary features, such as Cisco CleanAir technology, further enhance the performance of the 1300 series. This technology effectively detects and mitigates wireless interference, ensuring optimal performance and reliability in congested areas. Additionally, the series supports mesh networking capabilities, allowing for flexible deployment without the necessity of extensive wiring, which is particularly advantageous for temporary or mobile installations.

Management and configuration are simplified through the use of Cisco's Wireless LAN Controller (WLC). This centralized management allows network administrators to streamline firmware upgrades, monitor performance, and enforce policy compliance across multiple access points.

In summary, the Cisco Systems 1300 series access points combine robust outdoor capabilities with advanced wireless technology, security features, and ease of management, making them a valuable asset for organizations looking to extend their networking capabilities into outdoor environments. Through their durable design and innovative technologies, the Cisco 1300 series meets the demanding needs of today’s wireless landscape.
