Cable CPE Commands
cable-modem downstream saved channel
To modify the saved downstream channel setting and upstream power value on the cable interface, use
the cable-modem downstream saved channel command in cable interface configuration mode. To
remove the saved settings, which will be saved at the next initialization cycle, use the no form of this
command.
Cisco uBR904, uBR924 cable access routers
Note
Cisco IOS Release 12.1(2)T removed this command from the CLI for all platforms and reserved it for
exclusive use by the DOCSIS provisioning process.

Usage Guidelines
This command is auto-generated by the operation of the cable MAC layer process. The DOCSIS RFI
specification requires that CMs remember the downstream frequency and upstream power of the last
successfully ranged session. These arguments are called up as the first downstream frequency and
upstream power to use the next time the CM is booted. This operation dramatically speeds up the channel
search.
Use the no cable-modem downstream saved channel ds-frequency us-power command to remove the
saved frequency and power setting from the running configuration, which will be saved at the next
initialization cycle.

Downstream channel frequency in Hz, which can be from 91,000,000 to
860,000,000.
Upstream power level in decibels per millivolt (dBmV), which can be from 8 to
61.
Modification
This command was introduced for the Cisco uBR904 cable access router.
Support was added for the Cisco uBR924 cable access router.
This command was removed from the CLI for all platforms and reserved for
