Cisco CMTS Debugging Commands
debug cable interface
To display debug messages for a specific cable interface, or for traffic related to a specific MAC address
or Service ID (SID) on that interface, use the debug cable interface command in privileged EXEC
mode. To disable debugging output, use the no form of this command.
Syntax Description
slot/port
slot/subslot/port
mac-address address
mask
sid number
verbose
Defaults
Debugging for the cable interfaces is not enabled, which means most of the other debug cable
commands will not display any output, even when debugging is enabled.
Command Modes
Privileged EXEC
Command History
Release
12.0(6)T
Usage Guidelines
The debug cable interface command must be used to enable debugging on a cable interface before other
debug commands can be used on that interface. The mac-address and sid options can be used to restrict
the debug output to only those messages that are related to a specific MAC address or SID, so that the
volume of debug messages does not affect system performance.
OL-1581-08
debug cable interface cable {slot/port | slot/subslot/port} [mac-address address [mask] | sid
number] [verbose]
no debug cable interface cable {slot/port | slot/subslot/port} [mac-address address [mask] | sid
number] [verbose]
Identifies the cable interface and downstream port on the Cisco uBR7100
series and Cisco uBR7200 series routers.
On the Cisco uBR7100 series router, the only valid value is 1/0. On the
Cisco uBR7200 series router, slot can range from 3 to 6, and port can be 0
or 1, depending on the cable interface.
Identifies the cable interface on the Cisco uBR10012 router. The following
are the valid values:
•
slot = 5 to 8
subslot = 0 or 1
•
port = 0 to 4 (depending on the cable interface)
•
(Optional) Specifies that debugging is to be done only on traffic related to
the specified MAC address. An optional mask can be specified to indicate a
range of MAC addresses. The mask is ANDed with the address to determine
which bits of the address must match to be included in the debugging display.
(Optional) Specifies that debugging is to be done only on traffic related to
the specified SID. The valid range is 1 to 8191.
(Optional) Displays detailed debug information.
