Chapter 1 Overview of Cisco uBR10012 Universal Broadband Router Software
Supported Software Features for the Cisco uBR10012 Router
Automatic Revert Feature for HCCP N+1 Redundancy Switchover Events
Cisco IOS release 12.3(13a)BC introduces the Auto-Revert feature for the Cisco uBR10012 router, to
further enhance HCCP N+1 Redundancy on the Cisco CMTS. With this feature, when a switchover event
is performed in manual fashion, from the HCCP Protect line-card, and the Protect line-card has a
hardware fault, HCCP automatically reverts back to the HCCP Working line card. This is a very helpful
feature, in that periodic switchovers can be performed for regular maintenance or testing purposes, yet
subscriber service is not interrupted should such switchovers reveal unexpected problems with HCCP
Protect line cards.

Backup Path Testing for the Cisco RF Switch
Cisco IOS Release 12.3(13a)BC introduces the show hccp channel switch Cisco IOS command, wherein
the Cisco RF Switch communicates with each module in the chassis to provide information as
programmed in the RF Switch module bitmap. Cisco IOS Release 12.3(13a)BC performs polling every
10 seconds in response to this command, and reports RF Switch information as stored in cache. In normal
operation, the switch requires from two to five seconds for SNMP response.
If SNMP errors are detected in response to this command, the switch may require a significantly longer
timeout period. Cisco IOS Release 12.3(13a)BC introduces a keyboard break sequence to disrupt this
timeout in such circumstances.
To introduce a break for the
show hccp channel switch
command, use the
Ctrl-Shift-6-x
break
sequence—hold
Ctrl-Shift
keys, then press
6
then
x
.
After the break sequence, use the
show hccp g m channel
command to examine each individual HCCP
member of a group, as required.

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
