Chapter 2 Cisco Cable Modem Termination System Commands
To override hop decisions, use the cable upstream hopping blind command in cable interface
configuration mode. To stop blind hopping, enter the no form of this command.
cable upstream n hopping blind
no cable upstream n hopping blind
Defaults Disabled (hopping is optimized)
Command Modes Interface configuration (cable interface only)
Command History
Usage Guidelines Enter this command to override the hardware spectrum manager’s decision to optimize hopping.
Note Do not use this command unless you have a specific reason to disable optimum hopping configurations.
For example, if you are experimenting with a Cisco uBR-MC16S card, you can use this command to
enforce blind hopping on individual upstream channels.
Examples The following example shows how to specify hopping blind on the upstream port 0:
Related Commands
n Specifies the upstream port for which blind frequency hopping will be
activated. Valid values start with 0 for the first upstream port on the
cable interface line card.

Command Description
cable monitor Configures preset modulation profiles that you can apply to one or
more upstream cable interfaces when you identify and configure
spectrum groups.
cable spectrum-group (global
configuration)
Configures spectrum management characteristics for the given
spectrum group.
cable upstream channel-width Specifies the channel width of the given upstream cable interface.
cable upstream frequency Specifies the center frequency for a given upstream cable interface.
