Accessing the Cable Monitor
Note
The Cable Monitor is disabled by default, so the no ip http cable-monitor command does not need to
be included in the Cisco IOS configuration file that is downloaded to the router at power-on during the
DOCSIS provisioning. However, the Cisco web server is enabled by default; if this is not desirable, you
should include the no ip http server command in the Cisco IOS configuration file that is downloaded to
the Cisco uBR924 router.

When disabling the Cable Monitor, the console might display warning messages similar to the following:
% monitor-209.165.202.131 is not in the database.
% monitor-192.168.100.1 is not in the database.
% Range [209.165.202.131, 209.165.202.131] is not in the database.
% Range [192.168.100.1, 192.168.100.1] is not in the database.
These messages can be ignored because they are simply confirming that the IP addresses used for the
Cable Monitor are no longer being used for that purpose.

Note
The Cable Monitor can also be disabled by giving the no ip http server command, which disables all
web server access. However, this is not recommended because it does not release the system resources
that are specifically allocated to the Cable Monitor.

Accessing the Cable Monitor
The Cable Monitor can be accessed either through the cable interface (typically by technicians at the
headend or the service provider’s network operations center) or through the Ethernet interface (typically
by subscribers when the cable interface has gone down). See the following sections for more

Through the Cable Interface when the Cable Interface is Operational
During normal operations—when the Cisco uBR924 router is online and has connectivity with the
CMTS through the cable interface—service technicians at the headend can access the Cable Monitor by
doing the following:
