802.1x
This option enables support for users with 802.1x client software. The LPS-20x supports 802.1x client software that
uses EAP-TLS, EAP-TTLS, and PEAP.
RADIUS profile
Communications with the RADIUS server is handled via the access controller. This setting cannot be changed.
WEP encryption
Enable the use of dynamic WEP keys for all 802.1x sessions. Dynamic key rotation occurs on key 1, which is the
broadcast key. Key 0 is the pairwise key. It is automatically generated by the LPS-20x. Key length and key change
interval are set in the Dynamic keys box.
WEP
Key 1, 2, 3, 4
The number of characters you specify for a key determines the level of encryption the LPS-20x will provide.
• For 40-bit encryption, specify 5 ASCII characters or 10 HEX digits
• For 128-bit encryption, specify 13 ASCII characters or 26 HEX digits
When encryption is enabled, wireless stations that do not support encryption cannot communicate with the LPS-20x.
The definition for each encryption key must be the same on the LPS-20x and all client stations. Keys must also be in
the same position. For example, if you are using key 3 to encrypt transmissions, then each client station must also
define key 3 to communicate with the LPS-20x.
Transmission key
Select the key the LPS-20x will use to encrypt transmitted data. All four keys are used to decrypt received data.
Key format
Select the format you used to specify the encryption keys:
ASCII
ASCII keys are much weaker than carefully chosen HEX keys. You can include ASCII characters between 32 and
126, inclusive in the key. However, note that not all client stations support non-alphanumeric characters such as
spaces, punctuation, or special symbols in the key.
HEX
Your keys should only include the following digits: 0-9, a-f, A-F
DYNAMIC KEYS PARAMETERS
WEP key length
This setting determines the level of encryption the LPS-20x will provide for 802.1x and WPA.
Key Change Interval
Specifies how often key rotation occurs for 802.1x and WPA.
