Chapter1 Overview of CiscouBR10012 Universal Broadband Router Software
Supported Software Features for the CiscouBR10012 Router
Cable Monitor Support for Cisco MC5x20U-D and Cisco MC28U Broadband Processing Engines
Cisco IOS Release 12.3(13a)BC introduces support for the Cable Monitor feature for the Cisco
MC5x20U-D broadband processing engine (BPE) and the Cisco MC28U cable interface line card. These
field replaceable units (FRUs) apply to the Cisco uBR10012 router, and the latter to the Cisco
uBR7246VXR router. This feature enables intercept and monitoring capabilities for DOCSIS-compliant
frames.
Note The cable monitor feature does not support access lists for intelligent cable interface line cards such as
the Cisco MC28U or Cisco MC16U in the Cisco uBR7246VXR router, or any intelligent cable interface
line card in the Cisco uBR10012 router.
The Cable Monitor and Intercept features for Cisco Cable Modem Termination System (CMTS) routers
provide a software solution for monitoring and intercepting traffic coming from a cable network. This
feature also gives service providers Lawful Intercept capabilities, such as those required by the
Communications Assistance for Law Enforcement Act (CALEA).
The following example configures cable monitor for a specific interface and the associated MAC
addresses:
Router(config)# interface Cable3/0
Router(config-if)# cable monitor interface GigabitEthernet0/1
mac-address 000e.5cc8.fa5f
packet-type data ethernet
Router(config-if)#
mac-address 000e.5cac.59f8
packet-type data ethernet
To display cable monitor configuration and status information, use the show interfaces command in
PrivilegedEXEC mode:
Router# show interfaces cable 3/0 monitor
US/ Time Outbound Flow Flow Type Flow Packet MAC MACEncap
DS Stmp Interface Type Identifier Extn. Type Extn. TypeType
all no Gi0/1 mac-addr 000e.5cc8.fa5f yes data no -ethernet
all no Gi0/1 mac-addr 000e.5cac.59f8 yes data no -ethernet
To display and monitor traffic statistics and counters over time, use the show cable modem counters
and the show interfaces commands in Privileged EXEC mode, as illustrated:
Router# show interfaces cable 3/0 monitor
US/ Time Outbound Flow Flow Type Flow Packet MAC MACEncap
DS Stmp Interface Type Identifier Extn. Type Extn. TypeType
all no Gi0/1 mac-addr 000e.5cc8.fa5f yes data no -ethernet
all no Gi0/1 mac-addr 000e.5cac.59f8 yes data no -ethernet
Router# show cable modem 000e.5cac.59f8 counters
