ccsSpectrumDataTable
Table 3-9 lists the attributes in each entry of the ccsSpectrumDataTable table, which contains the results
for a spectrum request:
Note The ccsSpectrumRequestTable and ccsSpectrumDataTable tables provide the same information as that
provided by the show controllers cable upstream spectrum command.
Table 3-8 ccsSpectrumRequestTable Attributes
Attribute Type Description
ccsSpectrumRequestIndex Integer32 Arbitrary index to uniquely identify each table
entry.
ccsSpectrumRequestIfIndex InterfaceIndex
OrZero
Interface identifying the upstream.
ccsSpectrumRequestMacAddr MacAddress MAC address to specify an SNR value for a
particular cable modem, or 0000.0000.0000 to
indicate background noise for the entire
spectrum.
ccsSpectrumRequestUpperFreq CCSFrequency Upper frequency for the frequency range to be
monitored (5000 to 42000 KHz, with a default
of 42000 KHz).
ccsSpectrumRequestLowFreq CCSFrequency Lower frequency (in KHz) for the frequency
range to be monitored (5000 to 42000 KHz,
with a default of 5000 KHz).
ccsSpectrumRequestResolution Integer32 Requested resolution to determine how the
frequency range should be sampled (12 to
37000 KHz, with a default of 60 KHz).
ccsSpectrumRequestStartTime TimeStamp Time when the spectrum measurement began.
ccsSpectrumRequestStoppedTime TimeStamp Time when the spectrum measurement finished.
ccsSpectrumRequestOperation CCSRequestOp
eration

aborts the current one.
ccsSpectrumRequestOperState CCSRequestOp
erState
Provides the operational state of the current
spectrum management request.
ccsSpectrumRequestStatus RowStatus Controls the modification, creation, and
deletion of table entries.
