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)
Port number for the desired upstream (0 to 5).
(Optional) IP address, in dotted decimal notation, for a CM on the
specified upstream.
(Optional) MAC address, in dotted hexadecimal notation, for a CM on
the specified upstream.
Starting frequency for the frequency range that is being reported
(5 to 42 MHz; can also be specified as 5000 to 42000 KHz or
5000000 to 42000000 Hz).
Ending frequency for the frequency range that is being reported
(5 to 42 MHz).
The ending frequency must be greater than the starting
Note
frequency and must be specified using the same units as the
starting frequency (MHz, KHz, Hz).
Resolution frequency to determine the number of data points for the
report (12 to 37000 KHz).
The resolution frequency must be specified in the same units as
Note
the starting and ending frequency (MHz, KHz, Hz). To use a
resolution value less than 1 MHz, you must specify the other
parameters in either Hz or KHz.
