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 the default lifetime TEK to a CM so the CM can
access the network.
1. Use the interface cable command to enter Interface Configuration mode from
Global Configuration mode to configure the cable interface:
MOT(config)#
interface cable <
X
/
Y
>
where:
X
is 0.
Y
is the port number.
2. Use the cable privacy tek life-time command in Interface Configuration mode to
configure the global TEK lifetime value:
MOT(config-if)#
cable privacy tek life-time <
30-604800
>
where:
30-604800
is the TEK life-time value in seconds (the maximum value is 7
days).
Use the no cable privacy tek life-time command in Interface Configuration
mode if you need to restore the default:
MOT(config-if)#
no cable privacy tek life-time <
30-604800>
3. If a new life-time value is set for one or more CMs, use the cable privacy cm-tek
reset command, in Interface Configuration mode, to reset the life-time CM TEK
value:
TEK grace-time Temporary traffic key assigned to
CM 600 seconds 300 to 1,800
seconds
TEK lifetime More permanent TEK assigned to
CM after grace-time TEK expires 43,200 seconds 1,800 to
6,048,000
seconds
