Chapter1 Overview of CiscouBR10012 Universal Broadband Router Software
Supported Software Features for the CiscouBR10012 Router
Note The cable source-verify [dhcp] command (for cable interfaces) specifies that DHCP lease query
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.
CiscoNetwork Registrar supports the LEASEQUERY message type in CiscoIOSRelease3.01(T)
and later releases.
For configuration information, refer to the “Activating CM Upstream Address Verification” section on
page5.
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:
•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.
DOCSIS 1.1 CM Compatibility
DOCSIS 1.1 CMs can coexist with DOCSIS 1.0 and 1.0+ CMs in the same network—the
CiscouBR10012router provides the levels of service that are appropriate for each CM. For additional
configuration information, refer to Chapter3, “Configuring Cable Interface Features for the
CiscouBR10012Router.”
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.
Syntax Description
Several additional command options are available. Refer to the CiscoBroadband Cable Command
Reference Guide on Cisco.com.
Command Purpose
