for authentication
Use Default Key means that a default key (based off of the SM‘s MAC
address) will be used for authentication
Encryption
Specify the type of airlink security to apply to this AP:
Encryption Disabled provides no encryption on the air link. This is the
default mode.
Encryption Enabled provides encryption, using a factory-programmed
secret key that is unique for each module.
Encrypt Downlink Broadcast
When Encryption Enabled is selected in the Airlink Security parameter
(described above) and Enable is selected in the Encrypt Downlink
Broadcast parameter, the AP encrypts downlink broadcast packets as
DES where the AP is DES capable.
AES where the AP is AES capable.

that you specify ( IP Access Filtering Enabled ). If you select IP Access

IP Access Filtering Disabled for the IP Access Control
parameter, then no entries in this parameter are read, and access from all
IP addresses is permitted.
