Appendix G Configuring DHCP Option 43 for Lightweight Access Points

Configuring Option 43 for 1100, 1130, 1200, 1240, and 1300 Series Access Points

Configuring Option 43 for 1100, 1130, 1200, 1240, and 1300 Series Access Points

To configure DHCP Option 43 for Cisco Aironet 1100, 1130, 1200, 1240, and 1300 series lightweight access points in the embedded Cisco IOS DHCP server, follow these steps:

Step 1 Enter configuration mode at the Cisco IOS CLI.

Step 2 Create the DHCP pool, including the necessary parameters such as default router and name server. A DHCP scope example is as follows:

ip dhcp pool <pool name> network <IP Network> <Netmask> default-router<Default router> dns-server<DNS Server>

Where:

<pool name> is the name of the DHCP pool, such as AP1240

<IP Network> is the network IP address where the controller resides, such as 10.0.15.1 <Netmask> is the subnet mask, such as 255.255.255.0

<Default router> is the IP address of the default router, such as 10.0.0.1 <DNS Server> is the IP address of the DNS server, such as 10.0.10.2

Step 3 Add the option 60 line using the following syntax:

option 60 ascii “VCI string”

For the VCI string, use the value from Table G-1. The quotation marks must be included.

Step 4 Add the option 43 line using the following syntax:

option 43 hex <hex string>

The hex string is assembled by concatenating the TLV values shown below:

Type + Length + Value

Type is always f1(hex). Length is the number of controller management IP addresses times 4 in hex. Value is the IP address of the controller listed sequentially in hex.

For example, suppose that there are two controllers with management interface IP addresses, 10.126.126.2 and 10.127.127.2. The type is f1(hex). The length is 2 * 4 = 8 = 08 (hex). The IP addresses translate to 0a7e7e02 and 0a7f7f02. Assembling the string then yields f1080a7e7e020a7f7f02. The resulting Cisco IOS command added to the DHCP scope is listed below:

option 43 hex f1080a7e7e020a7f7f02

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.
