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.

Shutdown and No Shutdown Enhancement for Cable Interfaces

Cisco IOS release 12.3(13a)BC introduces a new behavior with the [no] shutdown interface

configuration command. In HCCP N+1 Redundancy schemes, an interface that is shut down with the

shutdown command does not create an HCCP Switchover event for the associated Working or Protect

interface. Instead, cable modems go offline and return online when the no shutdown command is issued.
