Using Cable Interface Debug Commands

Debug Spectrum Management

This command activates debugging of spectrum management (frequency agility) on the HFC network.

When this command is activated, messages generated because of spectrum group activity are displayed

on the Cisco uBR7200 series console. Spectrum group activity can be additions or changes to spectrum

groups, or frequency and power level changes controlled by spectrum groups. The format for the

command follows:

CMTS01# debug cable specmgmt

To deactivate debugging of cable spectrum management, use the no debug cable specmgmt command:

CMTS01# no debug cable specmgmt

Debug Channel Allocations

This command activates debugging of channel allocations on the HFC network. When this command is

activated, messages generated when channels are allocated to cable modems on the HFC network are

displayed on the Cisco uBR7200 series console. The format for the command follows:

CMTS01# debug cable startalloc

To deactivate debugging of cable channel allocations, use the no debug cable startalloc command:

CMTS01# no debug cable startalloc

Debug CMTS Transmissions

This command activates debugging of transmissions from the Cisco uBR7200 series across the HFC

network. When this command is activated, messages generated at the headend are displayed on the

Cisco uBR7200 series console. The format for the command follows:

CMTS01# debug cable transmit

To deactivate debugging of cable transmissions, use the no debug cable transmit command:

CMTS01# no debug cable transmit

Debug Upstream Channel Change (UCC) Messages

This command activates debugging of upstream channel change (UCC) messages generated when

cable modems request or are assigned a new channel. When this command is activated, messages

related to upstream channel changes are displayed on the Cisco uBR7200 series console. The format

for the command follows:

CMTS01# debug cable ucc

To deactivate debugging of cable upstream channel changes, use the following command:

CMTS01# no debug cable ucc
