-Both Open System and Shared Key. When you select both authentication algorithms, client stations configured to use WEP in shared key mode must have a valid WEP key in order to associate with the WAP device. Also, client stations configured to use WEP as an open system (shared key mode not enabled) can associate with the WAP device even if they do not have the correct WEP key.

Static WEP Rules

If you use Static WEP, these rules apply:

•All client stations must have the Wireless LAN (WLAN) security set to WEP, and all clients must have one of the WEP keys specified on the WAP device in order to decode AP-to-station data transmissions.

•The WAP device must have all keys used by clients for station-to-AP transmit so that it can decode the station transmissions.

•The same key must occupy the same slot on all nodes (AP and clients). For example, if the WAP device defines abc123 key as WEP key 3, then the client stations must define that same string as WEP key 3.

•Client stations can use different keys to transmit data to the access point. (Or they can all use the same key, but using the same key is less secure because it means one station can decrypt the data being sent by another.)

•On some wireless client software, you can configure multiple WEP keys and define a client station transfer key index, and then set the stations to encrypt the data they transmit using different keys. This ensures that neighboring access points cannot decode other access point transmissions.

•You cannot mix 64-bit and 128-bit WEP keys between the access point and its client stations.

Dynamic WEP

Dynamic WEP refers to the combination of 802.1x technology and the Extensible Authentication Protocol (EAP). With Dynamic WEP security, WEP keys are changed dynamically.

EAP messages are sent over an IEEE 802.11 wireless network using a protocol called EAP Encapsulation Over LANs (EAPOL). IEEE 802.1X provides dynamically generated keys that are periodically refreshed. An RC4 stream cipher is used to encrypt the frame body and cyclic redundancy checking (CRC) of each 802.11 frame.

WAP121, WAP321 specifications

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.
