Chapter 2 Cisco CMTS Configuration Commands
cable downstream rf-power
Command History
Usage Guidelines
The Cisco IOS command-line interface (CLI) allows the
hccp-delta
and
hccp-override
options to be
configured only on a Protect interface (an interface that has been configured with the
hccp protect
command). However, it is possible to manually edit a configuration file on a TFTP server so that it
includes these options on a Working interface configuration, and then download that configuration to the
router from the TFTP server.
Take care that if you manually edit Cisco IOS configuration files that you specify these options only on
Protect interfaces. If you specify the
hccp-delta
or
hccp-override
option on a Working interface, the
router will modify the configured downstream power with the given power delta or override value.
Examples
The following example shows the integrated upconverter on a Cisco uBR7100 series router being
configured for an RF output power level of 45 dBmV:
Router(config)#
cable interface 1/0
Router(config-if)#
cable downstream rf-power 45
The following example shows the first integrated upconverter on a Cisco uBR10012 router being
configured for an RF output power level of 53 dBmV:
Router(config)#
cable interface 5/1/0
Router(config-if)#
cable downstream rf-power 53
The following commands shows the first integrated upconverter being set to the default power level of
55 dBmV on the Cisco uBR10012 router:
Router(config)#
cable interface 5/1/0
Router(config-if)#
no cable downstream rf-power
Router(config-if)#
exit
Router(config)#
The following example shows a Protect interface being configured to add 3 dBmV to the current
Working RF power level when a switchover occurs:
Router(config)#
cable interface 6/0/0
Router(config-if)#
cable downstream rf-power hccp-delta 3
Router(config-if)#
exit
Router(config)#
The following example shows a Protect interface being configured to use an RF power level of 48 dBmV
instead of the current Working RF power level when a switchover occurs:
Router(config)#
cable interface 6/0/0
Router(config-if)#
cable downstream rf-power hccp-override 48
Router(config-if)#
exit
Router(config)#
Release
Modification
12.1(5)EC1
This command was introduced to provide support on the integrated
upconverter on the Cisco uBR7100 series router.
12.2(11)CY,
12.2(11)BC3
Support was added for the Cisco uBR10-MC5X20S cable interface line card
on the Cisco uBR10012 router.
12.2(15)CX
Support was added for the Cisco uBR-MC16U and Cisco uBR-MC28U
cable interface line card.
12.2(15)BC2
Support was added for the Cisco uBR-MC5X20U cable interface line cards.
Support was also added for the
hccp-delta
and
hccp-override
options.
