Chapter8 Troubleshooting the System
Using Cable Interface debug Commands
When this command is activated, messages generated when channels are allocated to cableinterfaces on
the HFC network are displayed on the CiscouBR10000series router console.
debug cable transmit (for CMTS Transmissions)
To activate the debugging of transmissions from the CiscouBR10000series 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.
debug cable transmit
no debug cable transmit
When this command is activated, messages generated at the headend are displayed on the
CiscouBR10000series router console.
debug cable ucc (for Upstream Channel Change Messages)
To activate the debugging of upstream channel change (UCC) messages generated when cableinterfaces
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.
debug cable ucc
no debug cable ucc
When this command is activated, messages related to upstream channel changes are displayed on the
CiscouBR10000series 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:
debug cable ucd
no debug cable ucd
UCD messages contain information about upstream channel characteristics and are sent to the
cablemodems 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
CiscouBR10000series router console.
