Initial Configuration

ƒThe Link LED turns green when 802.11 association completes. However, if the 802.1x authentication fails, the bridge becomes disassociated by the AP and the Link LED goes back to flashing red.

ƒThe bridge will not respond to discovery requests.

Once the bridge is authenticated, additional impacts include:

ƒRoaming

A bridge configured for WPA-PSK can only roam to APs that have WPA-PSK enabled in the same ESS.

A bridge configured for LEAP can only roam to APs that support LEAP, roaming, and are connected to the same RADIUS server.

ƒData Throughput and Latency

Round trip latency may increase and overall throughput may decrease, due to the additional steps to encrypt or decrypt data.

ƒRe-Keying

The session key may expire and the authentication process will be executed again causing streaming data to stop until a new key is authorized.
