System Security

This chapter describes how to configure security settings on the WAP device device.

It contains these topics:

RADIUS Server

802.1X Supplicant

Password Complexity

WPA-PSK Complexity

RADIUS Server

Several features require communication with a RADIUS authentication server. For example, when you configure Virtual Access Points (VAPs) on the WAP device, you can configure security methods that control wireless client access (see the Radio page). The Dynamic WEP and WPA Enterprise security methods use an external RADIUS server to authenticate clients. The MAC address filtering feature, where client access is restricted to a list, may also be configured to use a RADIUS server to control access. The Captive Portal feature also uses RADIUS to authenticate clients.

You can use the Radius Server page to configure the RADIUS servers that are used by these features. You can configure up to four globally available IPv4 or IPv6 RADIUS servers; however, you must select whether the RADIUS client operates in IPv4 or IPv6 mode with respect to the global servers. One of the servers always acts as a primary while the others act as backup servers.

NOTE In addition to using the global RADIUS servers, you can also configure each VAP to use a specific set of RADIUS servers. See the Networks page.

To configure global RADIUS servers:

Cisco Systems has long been recognized for its innovation in networking technologies, and the Cisco WAP321 and WAP121 access points are prime examples of its commitment to delivering reliable, high-performance wireless networking solutions for small and medium-sized businesses. These devices offer a robust set of features designed to meet the requirements of modern wireless networking while ensuring ease of use and deployment.

The Cisco WAP321 is a dual-band access point that operates in both the 2.4 GHz and 5 GHz frequency bands, providing flexibility and improved performance in crowded environments. With support for the 802.11n Wi-Fi standard, it boasts a combined data rate of up to 450 Mbps, enabling high-speed connections for multiple users simultaneously. The WAP321 also includes advanced features such as multiple SSIDs and VLAN support, allowing businesses to segment their networks for enhanced security and management control.

One of the standout characteristics of the WAP321 is its ability to act as a lightweight access point, meaning it can be managed through a Cisco Wireless LAN Controller (WLC) for larger deployments. This capability allows for centralized management of multiple access points, making it easier for IT administrators to deploy, configure, and monitor their network infrastructure.

On the other hand, the Cisco WAP121 is designed for those requiring a simpler, more cost-effective solution. This single-band access point also operates on the 2.4 GHz band but still provides robust performance with wireless speeds reaching up to 300 Mbps. It is ideal for small businesses looking to develop or expand their wireless networks without the complexities associated with more advanced systems.

Both models feature Power over Ethernet (PoE) capability, enabling them to receive power through the Ethernet cable, which simplifies installation and reduces the need for additional power outlets. Additionally, they support advanced security protocols, including WPA/WPA2 encryption, ensuring that sensitive data transmitted over the network remains protected from unauthorized access.

The ease of setup and user-friendly management interfaces of both the WAP321 and WAP121 make them appealing options for businesses lacking extensive IT resources. With features aimed at enhancing both performance and security, these access points represent powerful tools for achieving reliable wireless connectivity in a business environment. Whether organizations opt for the WAP321 for its extensive capabilities or the WAP121 for its simplicity, both access points reflect Cisco's dedication to meeting diverse networking needs.
