Chapter 2 Cisco Cable Modem Termination System Commands
cable upstream modulation-profile
Syntax Description
OL-1581-05
cable upstream modulation-profile
To assign one or two modulation profiles to an upstream port, use the cable upstream
modulation-profile command in cable interface configuration mode. To assign modulation profile 1 to
the upstream port and to disable the Dynamic Upstream Modulation feature, use the no form of this
command.
cable upstream n modulation-profile primary-profile-number [secondary-profile-number]
no cable upstream n modulation-profile primary-profile-number [secondary-profile-number]
Defaults A single primary modulation profile (profile 1)
Command Modes Interface configuration (cable interface only)
Command History
n Specifies the upstream port number. Valid values start with 0 for the
first upstream port on the cable interface line card.
primary-profile number Number identifying the primary modulation profile for the upstream
port. The primary modulation profile is used when the upstream is
operating with nominal noise conditions.
secondary-profile number Secondary modulation profile for the upstream port, which is used
when noise on the upstream increases to the point that the primary
modulation profile can no longer be used.
Note The secondary modulation profile should specify a more robust
performance profile (in terms of coping with noise) than the
primary profile.
Release Modification
11.3 NA This command was first introduced.
12.0(7)XR2 and 12.1(1a)T1 This command was introduced into the 12.0 and 12.1 release trains,
replacing the cable upstream modulation command.
12.1(3a)EC1 This command was modified to add the optional
secondary-profile-number parameter to enable the Dynamic
Upstream Modulation feature.
12.1(5)EC This command was introduced for the Cisco uBR7100 series
universal broadband routers.
12.1(7)CX1 This command was enhanced for the Cisco uBR-MC16S line card.
12.2(4)BC1 Support for this command was added for the Release 12.2 BC train.
12.2(8)BC2 Support for this command was added for the Cisco uBR-MC16S and
Cisco uBR-LCP2-MC16S line cards.
