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.
