VAP Configuration Changes
The WPS protocol on a WPS-enabled VAP may configure these parameters:
• Network SSID
• Key management options (WPA-PSK, or WPA-PSK and WPA2-PSK)
• Cryptography options (CCMP/AES, or TKIP and CCMP/AES)
• Network (public shared) key
If a VAP is enabled for WPS, these configuration parameters are subject to change,
and are persistent between reboots of the WAP device.
External Registration
The WAP device supports the registration with WPS External Registrars (ER) on
the wired and wireless LAN. On the WLAN, external registrars advertise their
capabilities within WPS-specific Information Elements (IEs) of their beacon frames;
on the wired LAN, external registrars announce their presence through UPnP.
WPS v2.0 does not require registration with an ER to be done explicitly through the
WAP device's user interface. The WAP device administrator can register the WAP
device with an ER by:
1. Entering the ER's PIN on the WAP device.
2. Entering the WAP device's PIN on the user interface of the ER.
The registration process can also configure the WAP device as specified in
Configuration Changes, page 101
WPS-specific IEs of its beacon frames or UPnP messages that it requires such
configuration.
The WAP device is capable of serving as a proxy for up to three external registrars
simultaneously.
Exclusive Operation of WPS Transactions
Any one VAP on the WAP device can be enabled for WPS. At most, one WPS
transaction (for example, enrollment and association of an 802. 1 1 client) can be in
progress at a time on the WAP device. The WAP device administrator can
terminate the transaction in progress from the web-based configuration utility. The
configuration of the VAP, however, should not be changed during the transaction;
nor should the VAP be changed during the authentication process. This restriction
is recommended but not enforced on the WAP device.
