Validation Tips
To verify if the upstream ports are activated or deactivated, enter the show interface cable command
for the upstream port that you have just configured:

Configure and Activate Baseline Privacy
To encrypt upstream and downstream data, you need to configure and activate baseline privacy.
Baseline privacy on an HFC network is configured with key encryption keys (keks) and traffic
encryption keys (teks). The encryption is based on 40-bit or 56-bit data encryption standard (DES)
encryption algorithms.
A kek is assigned to a cable modem based on the cable modem's service identifier (SID) and permits
the cable modem to connect to the Cisco uBR7246 when baseline privacy is activated. The tek is
assigned to a cable modem when its kek has been established. The tek is used to encrypt data traffic
between the cable modem and the Cisco uBR7246.
Keks and teks can be set to expire based on a grace-time or a life-time value. A grace-time key is
used to assign a temporary key to a cable modem to access the network. A life-time key is used to
assign a more permanent key to a cable modem. Each cable modem that has a life-time key assigned
will request a new life-time key from the Cisco uBR7246 before the current one expires.
Note
export-controlled feature. Check to make sure that the Cisco IOS software you are using supports
baseline privacy.

Make sure the cable connections are not loose or disconnected.
Make sure the cable modem card is firmly seated in its Cisco uBR7246 chassis slot.
Make sure that you have entered the correct slot and port numbers when you typed the command.
Make sure that you have entered the correct upstream port number. Currently this is always u0.
