SFID Support for Multicast and Cable Interface Bundling

Cisco IOS Release 12.3(9a)BC removes the prior restriction in Caveat CSCea45592 that prevented the

creation of DOCSIS 1.1 upstream packet classifiers and service flow IDs (SFIDs) when configuring

multicast groups with bundled cable interfaces. Cable interface bundling now supports SFIDs on

Multicast groups.

Note SFIDs map individual CPE devices to separate MPLS-Virtual Private Network (VPN) interfaces.

Note Cisco IOS Release with the Cisco uBR10012 router does not support overlapping IP addresses with

MPLS-VPN.

For additional configuration information, refer to the following document on Cisco.com:

Simple Network Management Protocol Cable Modem Remote Query

The cable modem remote-query command was introduced for the CiscouBR10012router in the Cisco

IOS Release 12.2(4)BC1b, and allows customers to query the cable modem performance statistics

directly from the cable modem termination system (CMTS).

Users can poll the cable modems periodically using Simple Network Management Protocol (SNMP) and

cache the information such as:

•IP address

•MAC address

•S/N ratio

•Upstream Transmit Power on the CMTS

This information helps the operators to know at a glance the state of a single modem and to have an

overall status of the plant. For configuration information, refer to the Configuring cable modem

remote-query Command at http://www.cisco.com/warp/public/109/remote_query.shtml.

Simple Network Management Protocol v3

SNMP version 3 offers enhanced security features and increases interoperability and ease of network

management. The implementation set of MIBs allows the SNMP manager to gather data such as system

card descriptions, serial numbers, hardware and software revision levels, and slot location. For

additional information, refer to the “Configuring Global Parameters” section on page8, and to the

“MIBs Changes and Updates in Cisco IOS Release 12.3(9a)BC” section on page69.

The CiscouBR10012router supports objects related to class of service. This aids in network management.
