Chapter 3 Spectrum Management for the Cisco Cable Modem Termination System
Monitoring Spectrum Management
The CISCO-CABLE-SPECTRUM-MIB has been enhanced to provide this SNMP support using the
following MIB attributes:
• ccsSNRRequestTable, page 3-52
• ccsSpectrumRequestTable, page 3-52
• ccsSpectrumDataTable, page 3-53
• ccsUpSpecMgmtTable, page 3-54
• ccsHoppingNotification, page 3-55
ccsSNRRequestTable
Table 3-7 lists the attributes in the ccsSNRRequestTable, which contains the CNR measurements that
are made for individual cable modems on an upstream:
ccsSpectrumRequestTable
Table 3-8 lists the attributes for each entry in the ccsSpectrumRequestTable table, which is used to obtain
the spectrum profile for a particular cable modem or to obtain the background SNR for an entire
upstream:
Table 3-7 ccsSNRRequestTable Attributes
Attribute Type Description
ccsSNRRequestIndex Integer32 Arbitrary index to uniquely identify each table
entry.
ccsSNRRequestMacAddr MacAddress MAC address of the remote online cable modem
being reported on.
ccsSNRRequestSNR Integer32 SNR value, in dB, that has been measured. This
value is 0 when the Operation State is
“running.”
ccsSNRRequestOperation CCSRequestOp
eration
Sets the current operation: start, pending,
running, or abort.
ccsSNRRequestOperState CCSRequestOp
erState
Reports on the current operation state: idle,
pending, running, noError, aborted, notOnLine,
invalidMac, timeOut, fftBusy, fftFailed, others.
ccsSNRRequestStartTime TimeStamp Contains the time when the SNR measurement
operation starts.
ccsSNRRequestStoppedTime TimeStamp Contains the time when the SNR measurement
stops.
ccsSNRRequestStatus RowStatus Controls the modification, creation, and
deletion of table entries.
