Baseline Privacy Interface Example
The Cisco uBR7200 series supports 56-bit and 40-bit encryption/decryption; 56 bit is the default. After
you choose a CMTS image that supports BPI, BPI is enabled by default for the Cisco
uBR7200 series.
Key commands that appear in the Cisco uBR7200 series configuration file that denote
encryption/decryption is supported include:
int cable 2/0
cable privacy kek grace-time 800
cable privacy kek life-time 750000
cable privacy tek grace-time 800
cable privacy tek life-time 56000
cable privacy enable
cable privacy mandatory
Note The cable modem must also support encryption/decryption.
When baseline privacy is enabled, the Cisco uBR7200 series routes encrypted/decrypted packets from a
host or peer to another host or peer. BPI is configured with key encryption keys (keks) and traffic
encryption keys (teks). A kek is assigned to a CM based on the CM’s service identifier (SID) and permits
the CM to connect to the Cisco
uBR7200 series router when baseline privacy is activated. The tek is
assigned to a CM when its kek has been established. The tek is used to encrypt data traffic between the
CM and the Cisco uBR7200 series router.
