LEAP

In order to function properly, a RADIUS server configured for LEAP containing

usernames/passwords, and an Access Point that supports LEAP, must be available. The

RADIUS server username and password must match the user-leap and pw-leap command

values configured on the WLN.

1.8.5 System Implementation Considerations

The WLN must be in infrastructure mode for WPA-PSK or LEAP to operate properly. A WLN

configured for WPA-PSK requires a connection to an AP with WPA-PSK enabled. A WLN

configured for LEAP requires a connection to an AP with LEAP enabled and connected to a

RADIUS server to provide authentication.

Until the WLN is authenticated by either the WPA-PSK enabled AP or the RADIUS server, no IP

network communication can proceed.

Symptoms of an unauthenticated client include:

 A WLN with serial-default set to “PASS” will not connect to the network client.

 A WLN configured for DHCP will not obtain host configuration from the DHCP server;

therefore, the IP address will remain 0.0.0.0.

 The Link LED turns on when 802.11 association completes. However, if the 802.1X

authentication fails, the WLN becomes disassociated by the AP, the Link LED turns off

and the RF_ACT LED will blink rapidly. In effect, the Link LED will blink slowly as the

process repeats.

 The WLN will not respond to discovery requests.

Once the WLN is authenticated, additional impacts include:

 Roaming

A WLN configured for WPA-PSK can only roam to APs that have WPA-PSK enabled in

the same ESS.

A WLN configured for LEAP can only roam to APs that support LEAP, roaming, and are

connected to the same RADIUS server.

 Data Throughput and Latency

Round trip latency may increase and overall throughput may decrease, due to the

additional steps to encrypt or decrypt data.

 Re-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.
