Configuring BPI involves the following tasks:
• Setting TEK Privacy
• Setting Authorization Key Values
• Displaying BPI Configuration Settings
Table 6-6 describes the BPI parameters.
Setting TEK Privacy
The TEK is assigned to a CM when its Key Encryption Key is established during the
CM registration process. The TEK encrypts data traffic between the CM and the cable
interface. The cable interface assigns a temporary grace-time TEK to a CM so the CM
can access the network. When the grace-time TEK expires, the CM must renew its
grace-time TEK with a lifetime TEK. The cable interface assigns a more permanent
lifetime TEK to a CM when the grace-time TEK expires.
1. To enter Interface Configuration mode from Global Configuration mode to
configure the cable interface, use the interface cable command, as shown below:
MOT(config)#interface cable <x>/<y>
where:
x is the slot number of the cable module.
y is the cable interface number.
