Supported Software Features for the Cisco uBR10012 Router
The cable source-verify [dhcp] command (for cable interfaces) specifies that DHCP lease query
Note
requests are sent to verify any unknown source IP address found in upstream data packets. Upstream
Address Verification requires a DHCP server that supports the new LEASEQUERY message type.
Cisco Network Registrar supports the LEASEQUERY message type in Cisco IOS Release 3.01(T)
and later releases.

DOCSIS BPI+ Multiple Root Certificate Support
Cisco IOS Release 12.3(13a)BC introduces support for multiple DOCSIS root certificates with Baseline
Privacy Interface Plus (BPI+) on the Cisco CMTS. This feature enables the Cisco CMTS to support
either North American or European cable modems, with the following guidelines for implementation:

DOCSIS 1.1 CM Compatibility
DOCSIS 1.1 CMs can coexist with DOCSIS 1.0 and 1.0+ CMs in the same network—the
Cisco uBR10012 router provides the levels of service that are appropriate for each CM. For additional
configuration information, refer to
Cisco uBR10012 Router."
DOCSIS 1.1 CM Database Manager
The CM Database Manager is a new software module that manages CM information on the CMTS. This
module can be queried to obtain different types of information on a single CM (or a group of CMs).
Using the show cable modem command, information maintained on a per-CM basis includes DOCSIS
MAC capabilities, counters, errors, QoS configuration, MAC state, connectivity statistics, and so forth.

Network".
In circumstances in which it is necessary to change from North American root certificates to
European root certificates, or vice versa, it is necessary to over write the existing root certificate on
the Cisco CMTS, and to reload the Cisco CMTS with the reload or restart command.
The Cisco uBR10-MC5X20S/U Broadband Processing Engine (BPE) supports both North American
and European root certificates at the same time, and simultaneous root certificate support is a
requirement in this case.
