Chapter 4 - Operation and Administration
4.2.6.7.1 Authentication Algorithm
The Authentication Algorithm option determines the operation mode of the
selected unit. The following two options are available:
Open System: An SU configured to Open System can only associate with an
AU also configured to Open System. In this case, the authentication
encryption algorithm is not used.
Shared Key: The authentication messages are encrypted. An SU configured to
use a Shared Key can only be authenticated by an AU configured to use a
Shared Key, provided the applicable Key (which means both the key number
and its content) in the AU is identical to the key selected as the Default Key in
the SU.
The default is Open System.
NOTE
The Shared Key option cannot be selected before at least one Key is defined. In the SU, a Default
Key that refers to a valid Key must be selected.
The AU and all the SUs it serves should be configured to the same Authentication Algorithm option.
Mixed operation is not supported.
4.2.6.7.2 Data Encryption Option
The Data Encryption Option allows enabling or disabling data encryption. When
enabled, all data frames, including frames using management protocols such as
Telnet, FTP, TFTP, SNMP, DHCP and ICMP, are encrypted.
The default is Disable.
NOTE
The AU and all the SUs it serves should be configured to the same Data Encryption Option.
Mixed operation is not supported.
An SU with Data Encryption Option enabled can accept non-encrypted data frames.
When the Data Encryption Option is enabled, the maximum number of SUs that can associate
with the AU is limited to 124. The Maximum Number of Associations Limit is indicated in the
Show Air Interface Parameters display.
4.2.6.7.3 Security Mode
The Security Mode option enables selecting the algorithm to be used for
encrypting the authentication messages and/or data frames.
Available options are WEP, AES/OCB and AES/CCM.
The default is WEP.
