Command History
Release
12.0(13)SC
12.1(5)EC1
12.1(6) and 12.1(6)T
Usage Guidelines
This command is never needed for normal operations, because downstream frequency override is
enabled by default for DOCSIS operations. However, this command can be used to disable the frequency
override feature for test and lab use, so as to force the CMs on that interface to use a particular
downstream frequency, regardless of the signal quality.
Because frequency override is enabled by default, this command does not appear as part of a cable
Note
interface's configuration section in the Cisco CMTS configuration file unless the no cable downstream
override command has been given.
Examples
The following example shows how to disable the downstream frequency override feature on a particular
cable interface:
router# configure terminal
router(config)# interface cable 6/0
router(config-if)# no cable downstream override
router(config-if)# exit
router(config)#
