8.4.4 STP Port States

STP assigns five port states (see next table) to eliminate packet looping. A bridge port is not
allowed to go directly from blocking state to forwarding state so as to eliminate transient
loops.

8.5 DFS

When you choose 802.11a in Access Point, Bridge/Repeater or AP+Bridge mode (NWA-
3160 only), the ZyXEL Device uses DFS (Dynamic Frequency Selection) to give you a wider
choice of wireless channels.
DFS allows you to use channels in the frequency range normally reserved for radar systems.
Radar uses radio signals to detect the location of objects for military, meteorological or air
traffic control purposes. As long as your ZyXEL Device detects no radar activity on the
channel you select, you can use the channel to communicate. However, a wireless LAN
operating on the same frequency as an active radar system could disrupt the radar system.
Therefore, if the ZyXEL Device detects radar activity on the channel you select, it
automatically instructs the wireless clients to move to another channel, then resumes
communications on the new channel.

8.6 Wireless Screen Overview

The following is a list of the wireless screens you can configure on the ZyXEL Device.
1 Configure the ZyXEL Device to operate in AP, Bridge/Repeater, AP+Bridge or
MBSSID mode in the Wireless screen (Bridge/Repeater and AP+Bridge modes are
available on the NWA-3160 and NWA-3163 only). You can also select an SSID Profile
in the Wireless screen.
2 Use the SSID screens to view and edit SSID profiles.
3 Use the Security screen to configure wireless profiles.
4 Use the RADIUS screen to configure RADIUS authentication and accounting settings.
5 Use the Layer-2 Isolation screen to prevent wireless clients associated with your
ZyXEL Device from communicating with other wireless clients, APs, computers or
routers in a network.
