8.5 Technical Reference
This section provides technical background information about the topics covered in
this chapter. Refer to Appendix B on page 319 for further readings on Wireless
LAN.
8.5.1 Spanning Tree Protocol (STP)
STP detects and breaks network loops and provides backup links between
switches, bridges or routers. It allows a bridge to interact with other STP-
compliant bridges in your network to ensure that only one route exists between
any two stations on the network.
8.5.1.1 Rapid STP
The NWA uses IEEE 802.1w RSTP (Rapid Spanning Tree Protocol) that allow faster

LABEL DESCRIPTION
Operating Mode Select MBSSID in this field to display the screen as shown
Select SSID Profile An SSID profile is the set of parameters relating to one of the NWA’s
BSSs. The SSID (Service Set IDentifier) identifies the Service Set
with which a wireless station is associated. Wireless stations
associating with the access point (AP) must have the same SSID.
Note: If you are configuring the NWA from a computer
connected to the wireless LAN and you change the
NWA’s SSID or security settings, you will lose your
wireless connection when you press Apply to confirm.
You must then change the wireless settings of your
computer to match the NWA’s new settings.
Index This is the index number of the SSID profile.
Active Select the check box to enable an SSID profile.
Profile Select the profile(s) of the SSIDs you want to use in your wireless
network. You can have up to eight BSSs running on the NWA
simultaneously, one of which is always the pre-configured
VoIP_SSID profile and another of which is always the pre-
configured Guest_SSID profile.
Configure SSID profiles in the SSID screen.
