Chapter 5. Using BCAdmin™
Setting the Access ID
The Access ID is a shared credential used by the AirFortress client to negotiate encryption keys. All devices that are to communicate with one another must share a common Access ID.
To set the Access ID on a BreadCrumb device, the BCAdmin workstation must be connected to the BreadCrumb device via the BreadCrumb device’s ethernet port. This is in order to prevent the transmission of the Access ID over an unsecured wireless connection that the Access ID will help to protect.
Important: In order to communicate to a BreadCrumb device via the BreadCrumb device’s ethernet port, the BreadCrumb device’s ethernet interface must be placed into Bridge Mode in the BreadCrumb device’s Reachback settings. If a BreadCrumb device does not have an ethernet port, you cannot set its Access ID.
If your BCAdmin workstation is connected to a BreadCrumb device via ethernet, be sure that the BCAdmin workstation’s radio is disabled in order to guarantee that the ethernet connection is in fact being used.
To set the Access ID on a BreadCrumb device, open the General tab of its Properties window and click the button "Change Access ID". You will be presented with a window resembling the following:
Figure 5-14. Set Access ID Window
If the button is disabled, check to ensure that you have registered the AirFortress client and that you are communicating with the BreadCrumb via its ethernet interface.
You must know the current Access ID in order to set a new one. The default Access ID on a BreadCrumb device is "0000000000000000" (16 zeros).
You must supply the new Access ID twice in order to prevent the inadvertent setting of an unknown Access ID.
Important: The Access ID change in a BreadCrumb device has an immediate effect. If you change the Access ID on a BreadCrumb device that has AirFortress encryption already running, you will have to change your BCAdmin workstation’s Access ID to match it in order to communicate with the BreadCrumb device again.
