Blind Hopping Support on the MC16S Modem Card for the Cisco uBR7200 Series Cable Router

Feature Overview

You can now bypass existing spectrum manager's hop configurations that are designed to optimize hopping and enforce blind hopping.

Benefits

Blind hopping is useful for experimenting with line cards. However, Cisco does not recommend that you use this feature for normal operations.

Command Reference

  This section describes the new cable upstream hopping blind command. All other commands used with this feature are documented in the Cisco IOS Release 12.0T command reference publications.

cable upstream hopping blind

To override hop decisions, enter the cable upstream hopping blind Interface configuration command. To stop blind hopping, enter the no form of this command.

cable upstream n hopping blind

no cable upstream n hopping blind

Syntax Description

n

Channel number.

Defaults

Disabled

Command Mode

Interface configuration

Command History

Release Modification

12.0(7)XR

This command was introduced.

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 an MC16S card, you can use this command to enforce blind hopping on individual upstream channels.

Example

router(config-if)# cable upstream 0 hopping blind

Related Commands

Command Description

show cable hop

Displays cable-hop statistics.
