Monitoring BPI+ Operations
See the following sections to monitor the state of BPI operations on the CMTS and its connected cable modems:
Displaying the Current BPI+ State of Cable Modems
To display the current BPI+ state of cable modems, use the show cable modem command. If used without
any options, this command displays the status for cable modems on all interfaces. You can also specify a
particular cable interface on the CMTS, or the IP address or MAC address for a specific cable modem:
Router# show cable modem
[ip-address
| interface
| mac-address
The MAC State column in the output of the show cable modem command displays the current status of each
cable modem. The following are the possible BPI-related values for this field:
Table 13: Possible show cable modem BPI+ States
DescriptionState
A cable modem has come online and, if configured
to use BPI+, is negotiating its privacy parameters for
the session. If the modem remains in this state for
more than a couple of minutes, it is online but not
using BPI+. Check that the cable modem is running
DOCSIS-certified software and is using a DOCSIS
configuration file that enables BPI+.
online
The cable modem is online and has negotiated a Key
Encryption Key(KEK) with the CMTS. If BPI+
negotiation is successful, this state will be shortly
followed by online(pt).
online(pk)
The cable modem is online and has negotiated a
Traffic Encryption Key (TEK) with the CMTS. The
BPI+ session has been established, and the cable
