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.

 

 

 

 

 

 

Enable Antenna

Select this to use antenna diversity. Antenna diversity uses multiple

 

 

Diversity

antennas to reduce signal interference.

 

 

 

 

 

 

Enable Breathing

Select this box to disable the WLAN LED (light). Clear this box to

 

 

LED

enable the WLAN LED.

 

 

 

 

 

 

Enable Spanning

(R)STP detects and breaks network loops and provides backup links

 

 

Tree Control (STP)

between switches, bridges or routers. It allows a bridge to interact

 

 

 

with other (R)STP -compliant bridges in your network to ensure that

 

 

 

only one path exists between any two stations on the network.

 

 

 

Select the check box to activate STP on the NWA.

 

 

 

 

 

 

Enable Roaming

Roaming allows wireless stations to switch from one access point to

 

 

 

another as they move from one coverage area to another. Select

 

 

 

this checkbox to enable roaming on the NWA if you have two or

 

 

 

more NWAs on the same subnet.

 

 

 

Note: All APs on the same subnet and the wireless stations

 

 

 

must have the same SSID to allow roaming.

8.4 Technical Reference

This section provides technical background information about the topics covered in this chapter.

8.4.1 Spanning Tree Protocol (STP)

Spanning Tree Protocol (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.

8.4.1.1 Rapid STP

The NWA uses IEEE 802.1w RSTP (Rapid Spanning Tree Protocol) that allow faster convergence of the spanning tree (while also being backwards compatible with STP-only aware bridges). Using RSTP topology change information does not have to propagate to the root bridge and unwanted learned addresses are flushed from
