DSX Messages and Synchronized PHS Information
Cisco IOS Release 12.3(17a)BC introduces support for PHS rules in a High Availability environment.
In this release, and later releases, PHS rules synchronize and are supported during a switchover event of
these types:
•Route Processor Redundancy Plus (RPR+), with Active and Standby Performance Routing Engines
(PREs)
•HCCP N+1 Redundancy, with Working and Protect cable interface line cards
For additional information about these enhancements, and related High Availability features, refer to the
following documents on Cisco.com:

Factory-Configured HCCP N+1 Redundancy
Cisco IOS release 12.3(13a)BC introduces factory-configured HCCP configurations at the
command-line interface (CLI) that allow plug-and-play operation of the Cisco RF switch in 7+1 HCCP
Redundancy configuration. This Cisco IOS release supports additional HCCP commands in global
configuration mode that automatically generate bitmaps and interface configuration for HCCP 7+1
line-card level redundancy.
For users in which maximum power is required, Cisco IOS Release 12.3(13a)BC continues to support
configurations supported in prior Cisco IOS Releases, making it possible to use the legacy HCCP
configuration for both 7+1 and 4+1 HCCP Redundancy in interface level implementation.

Globally Configured HCCP 4+1 and 7+1 Redundancy on the Cisco uBR10012 Router
Cisco IOS Release 12.3(17a)BC introduces support for globally-configured HCCP N+1 Redundancy on
the CiscouBR10012 router. Cisco IOS Release 12.3(17a)BC supports both 4+1 and 7+1 Redundancy,
in these High Availability configurations:
•7+1 Redundancy, supporting the Cisco uBR10012 router with two Cisco RF Switches
In this configuration, seven Working cable interface line cards are supported by one Protect cable
interface l ine card. Two Cisco RF Switches are connected to seven MC5X20U/D cable interface
line cards. Switchover events apply to an entire line card, rather than on an interface level, as in
