Using Cable Interface debug Commands

debug cable startalloc (for Channel Allocations)

To activate the debugging of channel allocations on the HFC network, use the debug cable startalloc
command in privileged EXEC mode. To deactivate debugging of cable channel allocations, use the no
form of this command.
When this command is activated, messages generated when channels are allocated to cable interfaces on
the HFC network are displayed on the Cisco uBR10012 router console.

debug cable transmit (for CMTS Transmissions)

To activate the debugging of transmissions from the Cisco uBR10012 router across the HFC network,
use the debug cable transmit command in privileged EXEC mode. To deactivate debugging of cable
transmissions, use the no form of this command.
When this command is activated, messages generated at the headend are displayed on the
Cisco uBR10012 router console.

debug cable ucc (for Upstream Channel Change Messages)

To activate the debugging of upstream channel change (UCC) messages generated when cable interfaces
request or are assigned a new channel, use the debug cable ucc command in privileged EXEC mode. To
deactivate debugging of cable upstream channel changes, use the no form of this command.
When this command is activated, messages related to upstream channel changes are displayed on the
Cisco uBR10012 router console.

debug cable ucd (for Upstream Channel Description Messages)

To activate the debugging of upstream channel descriptor (UCD) messages, use the debug cable ucd
command in privileged EXEC mode. To deactivate debugging of cable upstream channel descriptor, use
the no form of this command:
UCD messages contain information about upstream channel characteristics and are sent to the
cable modems on the HFC network. CMs that are configured to use enhanced upstream channels use
these UCD messages to identify and select an enhanced upstream channel to use. When this command
is activated, messages related to upstream channel descriptors are displayed on the
Cisco uBR10012 router console.
