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

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

Diversity

Select this to use antenna diversity. Antenna diversity uses multiple

antennas to reduce signal interference.

Enable Breathing

LED

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

enable the WLAN LED.

Enable Spanning

Tree Control (STP)

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

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.
