debug cable interface
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
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
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.
slot/port
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.
slot/subslot/port
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)
mac-address
address
mask
(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.
sid
number
(Optional) Specifies that debugging is to be done only on traffic related to
the specified SID. The valid range is 1 to 8191.
verbose
(Optional) Displays detailed debug information.
