Chapter4 Troubleshooting the System Using Cable Interface Debug Commands
Debug Spectrum Management
This command activatesdebugging of spectrum management (frequency agility) on the HFC network.
Whenthis command is activated, messages generated because of spectrum group activity are displayed
onthe Cisco uBR7200series 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
Todeactivate debugging of cable spectrum management, use the no debug cable specmgmt command:
CMTS01# no debug cable specmgmt
Debug Channel Allocations
Thiscommand activates debugging of channel allocations on the HFC network. When this command is
activated, messages generated when channels are allocated to cablemodems 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 theno debug cable startalloc command:
CMTS01# no debug cable startalloc
Debug CMTS Transmissions
This command activates debugging of transmissions from the CiscouBR7200 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 thecommand follows:
CMTS01# debug cable transmit
To deactivate debugging of cable transmissions, use theno 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
