WPS Setup

 

 

 

 

 

WPS maintains network security by requiring both the users of new client devices and WLAN administrators to have either physical access to their respective devices or secure remote access to these devices.

Usage Scenarios

These are typical scenarios for using WPS:

•A user wishes to enroll a client station on a WPS-enabled WLAN. (The enrolling client device may detect the network, and prompt the user to enroll, although this is not necessary.) The user triggers the enrollment by pushing a button on the client device. The WAP device's administrator then pushes a button on the WAP device. During a brief exchange of WPS protocol messages, the WAP device supplies the new client with a new security configuration through Extensible Authentication Protocol (EAP). The two devices disassociate, and then reassociate and authenticate with the new settings.

•A user wishes to enroll a client station on a WPS-enabled WLAN by supplying the WAP device administrator with the PIN of the client device. The administrator enters this PIN in the configuration utility of the WAP device and triggers the device enrollment. The new enrollee and the WAP device exchange WPS messages, including a new security configuration, disassociate, reassociate, and authenticate.

•A WAP device administrator purchases a new WAP device that has been certified by the Wi-Fi Alliance to be compliant with WPS version 2.0, and wishes to add the WAP device to an existing (wired or wireless) network. The administrator turns on the WAP device, and then accesses a network host that supports the WPS registration protocol. The administrator enters the PIN of the WAP device in the configuration utility of this external registrar, and triggers the WPS registration process. (On a wired LAN, the WPS protocol messages are transported through Universal Plug and Play, or UPnP, protocol.) The host registers the WAP as a new network device and configures the WAP with new security settings.

•A WAP device administrator has just added a new WAP device to an existing (wireless or wired) network through WPS, and wishes to grant network access to a new client device. The device is enrolled through either the PIN or Push-Button Control (PBC) methods described above, but this time the device enrolls with the external registrar, with the WAP device acting solely as a proxy.

•A wireless device that does not support WPS must join the WPS-enabled WLAN. The administrator, who cannot use WPS in this case, instead

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.
