Webpage Auto Update
Enter the frequency (in seconds) for the web browser to automatically refresh the web-
based interface. The default setting is 0. The 0 setting causes the web-based interface to
never be automatically refreshed.
Airlink Security
Specify the type of air link 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
In Release 4.2 or later release, 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.
CAUTION!
Do not select Enable for this parameter until all SMs that will register to
this AP operate on Release 4.2 or a later release. An SM that operates
on an earlier release cannot decrypt encrypted broadcasts and,
consequently, drops connectivity (or cannot establish a link) with the AP
that is configured to encrypt downlink broadcasts.
For more information about the Encrypt Downlink Broadcast feature, see Encrypting
Downlink Broadcasts on Page 305.
SM Scan Privacy
When the SM Scan Privacy feature is enabled, you can use this field to suppress the
display of data about this AP on the AP Eval Data page of all SMs that register.
Authentication Mode
If the AP has authentication capability, then you can use this field to select from among
the following authentication modes:
◦ Authentication Disabled—the AP requires no SMs to authenticate.
◦ Authentication Required—the AP requires any SM that attempts registration to
be authenticated in the BAM server before registration.
◦ Authentication Optional—the AP requires all SMs that attempt registration to
be authenticated before registration, except any SM that is operating on a
Canopy system release of earlier than Release 3.0. (These earlier releases
did not support authentication for SMs.) This value is not recommended.
