WPS Setup
Cisco Small Business WAP121 and WAP321 Wireless-N Access Point with PoE
REVIEW DRAFT Version 2—CISCO CONFIDENTIAL
WPS is a standard that enables simple establishment of wireless networks
without compromising network security. It relieves both the wireless client users
and the AP administrators from having to know network names, keys, and various
other cryptographic configuration options.
WPS facilitates network setup by allowing the administrator to use a push button
or PIN mechanism to establish wireless networks, thereby avoiding the manual
entry of network names (SSIDs) and wireless security parameters:
•
: The WPS button is either on the product or a clickable button
on the user interface.
•
product label or can be viewed on product user interface.
WPS maintains network security during these simple steps by requiring both the
users of new client devices and WLAN administrators to either have physical
access to their respective devices or secure remote access to these devices.
Typical scenarios for using WPS include the following:
•
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 device. The AP's administrator then pushes a button
on the AP. During a brief exchange of WPS protocol messages, the AP
supplies the new client with a new security configuration via the 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 AP administrator with the PIN of the client device. The
administrator enters this PIN on the UI of the AP and triggers the device
enrollment. The new enrollee and the AP exchange WPS messages,
including a new security configuration, disassociate, reassociate, and
authenticate.
•
An AP administrator purchases a new AP that has been certified by the
Wi-Fi Alliance to be compliant with WPS version 2.0, and wishes to add the
AP to an existing (wired or wireless) network. The administrator turns on the
AP, and then accesses a network host that supports the WPS registration
protocol. The administrator enters the AP device's pin on the UI of this
: The PIN either is located on a
