Cisco Broadband Cable Command Reference Guide
Chapter 5 Cable CPE Commands
When the cable access router has established connectivity with the CMTS over the cable interface,
a service technician can use a web browser to remotely access the router and display the desired
information.
When the cable network is not operational and the cable access router is not online, the subscriber
can access the tool with a PC connected to the router’s Ethernet ports. Technicians can then prompt
the user for the information they need to determine the source of the problem.
Enabling the Cable Monitor also enables the Cisco web server that is onboard the cable access router,
which is the equivalent to entering the ip http server command. However, when the Cable Monitor is
enabled, all other access, including CLI access, to the onboard web server is automatically disabled.
Note When the Cable Monitor is enabled in the startup configuration file, the messages “Starting DNS
process” and “Terminating DNS process” can appear in the messages displayed during boot-up on the
console. These messages are normal and can be ignored.
Disabling the Cable Monitor using the no ip http cable-monitor command also automatically disables
the Cisco web server, which is the equivalent of giving the no ip http server command. 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.
The URL-IP-address and URL-mask arguments also specify that the class C private network
192.168.100.0 is the default address pool for the temporary DHCP server that activates when the cable
interface goes down.
Note The Cable Monitor web interface does not work with the Cisco Easy VPN Remote web interface. To
access the Cable Monitor web interface, you must first disable the Cisco Easy VPN Remote web
interface with the no ip http ezvpn command, and then enable the Cable Monitor with the ip http
cable-monitor command.
Examples The following example shows how to enable the Cable Monitor for advanced mode, in which all status
and diagnostic pages are displayed:
Router(config)# ip http cable-monitor advance
Router(config)#
The following example shows how to disable both the Cable Monitor and the Cisco web server,
preventing all web server access to the Cisco uBR924 cable access router:
Router(config)# no ip http cable-monitor
Router(config)#
