Cisco uBR7200 Series Universal Broadband Router Software Configuration Guide
OL-2239-05
Chapter1 Overview of Cisco uBR7200 Series Software
Supported Software Features for the Cisco uBR7200 Series
Note HCCP support for the Cisco uBR-MC16S card exists only in Cisco IOS Release 12.1(7)EC or later, so
you cannot use the advanced spectrum management features in Cisco IOS Release 12.1(7)CX with
HCCP 1+1 redundant configuration.
HCCP N+1 Redundancy
HCCP N+1 Redundancy is made possible with the addition of the Cisco RF Switch to your cable
headend network. Together with the Cisco uBR10012 and/or the Cisco uBR7246VXR routers, the Cisco
RF Switch provides a fully redundant system that enables cable operators to achieve PacketCable system
availability, minimize service disruptions, and simplify operations.
HCCP N+1 Redundancy is an important step toward high availability on CMTS and telecommunications
networks that use broadband media. HCCP N+1 Redundancy can help limit Customer Premises
Equipment (CPE) downtime by enabling robust automatic switchover and recovery in the event that
there is a localized system failure.
Beginning with Cisco IOS Release 12.2(15)BC2, HCCP N+1 Redundancy adds synchronization
between HCCP Working interface configurations and those inherited upon switchover to HCCP Protect
interfaces. This makes the configuration of both easier and switchover times faster.

High Availability Features in CiscoIOS Release 12.3(13a)BC
Cisco IOS Release 12.3(13a)BC removes support for HCCP N+1 Redundancy on the Cisco uBR7200
series routers. Associated configuration, show, and debug commands are not supported in this release.
Note The latest release to support HCCP N+1 Redundancy for the Cisco uBR7200 Series is Cisco IOS release
12.3(9a)BC. When upgrading from this or earlier supporting Cisco IOS releases to Cisco IOS release
12.3(13a)BC, the HCCP configurations are discarded and not retained.
HCCP N+1 Redundancy for the Cisco CMTS is described for earlier releases in this and additional
documents on Cisco.com:

High Availability Support for Encrypted IP Multicast
Cisco IOS Release 12.3(17a)BC introduces support for IP Multicast streams during switchover events
in a High Availability environment. This feature is supported for Route Processor Redundancy Plus
(RPR+), N+1 Redundancy, and encrypted BPI+ streams.
