ciscoCableSpectrumMIB 1.3.6.1.4.1.9.9.114
This is the MIB Module for Cable Spectrum Management for DOCSIS-compliant Cable Modem Termination Systems (CMTS). Spectrum management is a software/hardware feature provided in the CMTS so that the CMTS may sense both downstream and upstream plant impairments, report them to a management entity, and automatically mitigate them where possible. The CMTS directly senses upstream transmission errors.It may also indirectly monitor the condition of the plant by keeping a record of modem state changes. It is desireable to perform these functions without reducing throughput or latency and without creating additional packet overhead on the RF plant. The purpose of cable Spectrum Management is to prevent long term service interruptions caused by upstream noise events in the cable plant. It is also used for fault management and trouble shooting the cable network. When modems are detected to go on-line and off-line by flap detectors, the cable operators can look at the flap list and spectrum tables to determine the possible causes.

ccsFlapListMaxSize 1.3.6.1.4.1.9.9.114.1.1.1
The maximum number of flapped modem entries (ccsCmFlapEntry) per Cable downstream interface that can be reported in the ccsCmFlapTable. If the Cable downstream interface has more flapped modems than the ccsFlapListMaxSize, some of the flapped modems will not be shown in the ccsCmFlapTable. In this case, the users may want to increase the ccsFlapMaxSize.
OBJECT-TYPE    
  Integer32 1..65536  

ccsFlapListCurrentSize 1.3.6.1.4.1.9.9.114.1.1.2
The total number of flapped modem entries (ccsCmFlapEntry) that reported in the ccsCmFlapTable. The maximum value will be ccsFlapListMaxSize * .
OBJECT-TYPE    
  Gauge32 0..65536  

ccsFlapAging 1.3.6.1.4.1.9.9.114.1.1.3
The flap entry aging threshold. Periodically, the aging process scans through the flap list and removes the cable modems that have not flapped for that many minutes.
OBJECT-TYPE    
  Integer32 1..86400  

ccsFlapInsertionTime 1.3.6.1.4.1.9.9.114.1.1.4
The insertion-time is an empirically derived, worst-case number of seconds which the cable modem requires to complete registration. The time taken by cable modems to complete their registration is measured by the cable operators and this information helps to determine the insertion time. If the cable modem has not completed the registration stage within this insertion-time setting, the cable modem will be inserted into the flap-list.
OBJECT-TYPE    
  Integer32 60..86400  

ccsFlapTable 1.3.6.1.4.1.9.9.114.1.1.5
This table keeps the records of modem state changes. It can be used to identify the problematic cable modems. An entry can be deleted from the table but can not be added to the table.
OBJECT-TYPE    
  SEQUENCE OF  
    CcsFlapEntry

ccsFlapEntry 1.3.6.1.4.1.9.9.114.1.1.5.1
List of attributes for an entry in the ccsFlapTable. An entry in this table exists for each cable modem that triggered one of our flap detectors.
OBJECT-TYPE    
  CcsFlapEntry  

ccsFlapMacAddr 1.3.6.1.4.1.9.9.114.1.1.5.1.1
MAC address of the Cable Modem's Cable interface which identifies a flap-list entry for a flapping Cable Modem.

OBJECT-TYPE    
  InterfaceIndex  

ccsFlapInsertionFails 1.3.6.1.4.1.9.9.114.1.1.5.1.4
The number of times a Cable Modem registered more frequently than expected. Excessive registration is defined as the presence of a time span between two successive registration cycles which is less than a threshold span (ccsFlapInsertionTime). A Cable Modem may fail the ranging or registration process due to not being able to get an IP address. When the Cable Modem can not finish registration within the insertion time, it retries the process and sends the Initial Maintenance packet again. CMTS will receive the Initial Maintenance packet from the Cable Modem sooner than expected and the Cable Modem is considered a flapping modem. This count may indicate: Intermittent downstream sync loss, or DHCP or modem registration problems. The Flap Count (ccsFlapTotal) will be incremented when this counter is incremented. Discontinuites in the value of this counter can occur if this entry is removed from the table and then re-added, and are indicated by a change in the value of ccsFlapCreateTime.
OBJECT-TYPE    
  Counter32  

ccsFlapHits 1.3.6.1.4.1.9.9.114.1.1.5.1.5
The number of times the CMTS receives the Ranging request from the Cable Modem. The CMTS issues a Station Maintenance transmit opportunity at a typical rate of once every 10 seconds and waits for a Ranging request from the Cable Modem.If the CMTS receives a Ranging request then the Hit count will be increased by 1 If the FlapTotal count is high,both Hits and Misses counts are high, and other counters are relatively low then the flapping is probably caused by the modem going up and down. The Hits and Misses counts are keep-alive polling statistics. The Hits count should be much greater than the Misses count Discontinuites in the value of this counter can occur if this entry is removed from the table and then re-added, and are indicated by a change in the value of ccsFlapCreateTime.
OBJECT-TYPE    
  Counter32  

ccsFlapMisses 1.3.6.1.4.1.9.9.114.1.1.5.1.6
The number of times the CMTS misses the Ranging request from the Cable Modem. The CMTS issues a Station Maintenance packet every 10 seconds and waits for a Ranging request from the Cable Modem. If the CMTS misses a Ranging request within 25 msec then the Misses count will be incremented. If ccsFlapTotal is high, Hits and Misses are high but ccsFlapPowerAdjustments and ccsFlapInsertionFails are low then the flapping is probably caused by the modem going up and down. Miss counts can indicate: Intermittent upstream, Laser clipping, or Noise bursts. Laser clipping can happen if the signal power is too high when the upstream electrical signal is converted to an optical signal. When it happens the more input produces less output, until finally there is no more increase in output. This phenomena is called laser clipping. Discontinuites in the value of this counter can occur if this entry is removed from the table and then re-added, and are indicated by a change in the value of ccsFlapCreateTime.
OBJECT-TYPE    
  Counter32  

ccsFlapCrcErrors 1.3.6.1.4.1.9.9.114.1.1.5.1.7
The number of times the CMTS upstream receiver flagged a packet with a CRC error. If ccsFlapCrcErrors is high, it indicates the cable upstream may have high noise level. The modem may not be flapping yet but it may be a potential problem. This count can indicate: Intermittent upstream, Laser clipping, or Noise bursts. Laser clipping can happen if the signal power is too high when the upstream electrical signal is converted to an optical signal. When it happens the more input produces less output, until finally there is no more increase in output. This phenomena is called laser clipping. Discontinuites in the value of this counter can occur if this entry is removed from the table and then re-added, and are indicated by a change in the value of ccsFlapCreateTime.
OBJECT-TYPE    
  Counter32  

ccsFlapPowerAdjustments 1.3.6.1.4.1.9.9.114.1.1.5.1.8
The number of times the Cable Modem upstream transmit power is adjusted during station maintenance. When the adjustment is greater than the power adjustment threshold the counter will be incremented. The power adjustment threshold is chosen in an implementation-dependent manner. The Flap Count (ccsFlapTotal) will be incremented when this counter is incremented. If ccsFlapTotal is high, ccsFlapPowerAdjustments is high but the Hits and Misses are low and ccsFlapInsertionFails are low then the flapping is probably caused by an improper transmit power level setting at the modem end. This count can indicate: Amplifier degradation, Poor connections, or Wind, moisture, or temperature sensitivity. Discontinuites in the value of this counter can occur if this entry is removed from the table and then re-added, and are indicated by a change in the value of ccsFlapCreateTime.
OBJECT-TYPE    
  Counter32  

ccsFlapTotal 1.3.6.1.4.1.9.9.114.1.1.5.1.9
Whenever the Cable Modem passes flap detection, then the flap counter is increased. There are 3 flap detectors defined: (1) When ccsFlapInsertionFails is increased the Flap count will be increased. (2) When the CMTS receives a Miss followed by a Hit then the Flap count will be increased. (3) When ccsFlapPowerAdjustments is increased the Flap count will be increased. Discontinuites in the value of this counter can occur if this entry is removed from the table and then re-added, and are indicated by a change in the value of ccsFlapCreateTime.

ccsFlapCreateTime 1.3.6.1.4.1.9.9.114.1.1.5.1.11
The time that this entry was added to the table. If an entry is removed and then later re-added, there may be a discontinuity in the counters associated with this entry. This timestamp can be used to detect those discontinuities.
OBJECT-TYPE    
  DateAndTime  

ccsFlapRowStatus 1.3.6.1.4.1.9.9.114.1.1.5.1.12
Controls and reflects the status of rows in this table. When a cable modem triggers a flap detector, if an entry does not already exist for this cable modem, and ccsFlapListCurrentSize is less than ccsFlapListMaxSize, then an entry will be created in this table. The new instance of this object will be set to active(1). All flapping modems have the status of active(1). Active entries are removed from the table after they have not triggered any additional flap detectors for the period of time defined in ccsFlapAging. Alternatively, setting this instance to destroy(6) will remove the entry immediately. createAndGo(4) and createAndWait(5) are not supported.

ccsFlapHitNum 1.3.6.1.4.1.9.9.114.1.1.5.1.14
The number of times the CMTS receives the Ranging request from the Cable Modem. The CMTS issues a Station Maintenance transmit opportunity at a typical rate of once every 10 seconds and waits for a Ranging request from the Cable Modem. If the CMTS receives a Ranging request then the Hit number will be increased by 1 If the FlapTotal object is high, both Hit and Miss objects are high, and other statistical objects are relatively low then the flapping is probably caused by the modem going up and down. The Hit and Miss objects keep-alive polling statistics. The Hit object should be much greater than the Misses count.

  DateAndTime  

ccsCmFlapInsertionFailNum 1.3.6.1.4.1.9.9.114.1.1.11.1.6
The number of times a Cable Modem registered more frequently than expected. Excessive registration is defined as the presence of a time span between two successive registration cycles which is less than a threshold span (ccsFlapInsertionTime). A Cable Modem may fail the ranging or registration process due to not being able to get an IP address. When the Cable Modem can not finish registration within the insertion time, it retries the process and sends the Initial Maintenance packet again. CMTS will receive the Initial Maintenance packet from the Cable Modem sooner than expected and the Cable Modem is considered a flapping modem. This object may indicate: Intermittent downstream sync loss, or DHCP or modem registration problems. The Flap number (ccsCmFlapTotalNum) will be incremented when this object is incremented. The value of this object can be reset to zero if this entry is removed from the table and then re-added, or if the ccsCmFlapResetNow object was set to true(1). The value of the object ccsCmFlapLastResetTime indicates the last reset time.

ccsCmFlapHitNum 1.3.6.1.4.1.9.9.114.1.1.11.1.7
The number of times the CMTS receives the Ranging request from the Cable Modem. The CMTS issues a Station Maintenance transmit opportunity at a typical rate of once every 10 seconds and waits for a Ranging request from the Cable Modem. If the CMTS receives a Ranging request then the Hit number will be increased by 1 If the FlapTotal object is high, both Hit and Miss objects are high, and other statistical objects are relatively low then the flapping is probably caused by the modem going up and down. The Hit and Miss objects keep-alive polling statistics. The Hit object should be much greater than the Misses count. The value of this object can be reset to zero if this entry is removed from the table and then re-added, or if the ccsCmFlapResetNow object was set to true(1). The value of the object ccsCmFlapLastResetTime indicates the last reset time.

ccsCmFlapMissNum 1.3.6.1.4.1.9.9.114.1.1.11.1.8
The number of times the CMTS misses the Ranging request from the Cable Modem. The CMTS issues a Station Maintenance packet every 10 seconds and waits for a Ranging request from the Cable Modem. If the CMTS misses a Ranging request within 25 msec then the Miss Object will be incremented. If ccsCmFlapTotalNum is high, Hit and Miss are high but ccsCmFlapPowerAdjustmentNum and ccsCmFlapInsertionFailNum are low then the flapping is probably caused by the modem going up and down. Miss object can indicate: Intermittent upstream, Laser clipping, or Noise bursts. Laser clipping can happen if the signal power is too high when the upstream electrical signal is converted to an optical signal. When it happens the more input produces less output, until finally there is no more increase in output. This phenomena is called laser clipping. The value of this object can be reset to zero if this entry is removed from the table and then re-added, or if the ccsCmFlapResetNow object was set to true(1). The value of the object ccsCmFlapLastResetTime indicates the last reset time.

ccsCmFlapCrcErrorNum 1.3.6.1.4.1.9.9.114.1.1.11.1.9
The number of times the CMTS upstream receiver flagged a packet with a CRC error. If ccsCmFlapCrcErrorNum is high, it indicates the cable upstream may have high noise level. The modem may not be flapping yet but it may be a potential problem. This object can indicate: Intermittent upstream, Laser clipping, or Noise bursts. Laser clipping can happen if the signal power is too high when the upstream electrical signal is converted to an optical signal. When it happens the more input produces less output, until finally there is no more increase in output. This phenomena is called laser clipping. The value of this object can be reset to zero if this entry is removed from the table and then re-added, or if the ccsCmFlapResetNow object was set to true(1).

ccsCmFlapPowerAdjustmentNum 1.3.6.1.4.1.9.9.114.1.1.11.1.10
The number of times the Cable Modem upstream transmit power is adjusted during station maintenance. When the adjustment is greater than the power adjustment threshold the number will be incremented. The power adjustment threshold is chosen in an implementation-dependent manner The Flap number (ccsCmFlapTotalNum) will be incremented when this object is incremented. If ccsCmFlapTotalNum is high, ccsCmFlapPowerAdjustmentNum is high but the Hit and Miss are low and ccsCmFlapInsertionFailNum are low then the flapping is probably caused by an improper transmit power level setting at the modem end. This object can indicate: Amplifier degradation, Poor connections, or Wind, moisture, or temperature sensitivity. The value of this object can be reset to zero if this entry is removed from the table and then re-added, or if the ccsCmFlapResetNow object was set to true(1). The value of the object ccsCmFlapLastResetTime indicates the last reset time.

There are 3 flap detectors defined: (1) When ccsCmFlapInsertionFailNum is increased the Flap number will be increased. (2) When the CMTS receives a Miss followed by a Hit then the Flap number will be increased. (3) When ccsCmFlapPowerAdjustmentNum is increased the Flap number will be increased. The value of this object can be reset to zero if this entry is removed from the table and then re-added, or if the ccsCmFlapResetNow object was set to true(1).

ccsUpSpecMgmtCriteria 1.3.6.1.4.1.9.9.114.1.3.1.1.23
Defines the criteria that trigger a change in frequency hopping, modulation or channel width. Depending on the type of linecards, the criteria are slightly different: For the linecards that have no Hardware Based Spectrum Management capability like the uBR-MC1xC, change in modulation or frequency occurs in the following criteria: 1) Change from modulation profile 1 to modulation profile 2 would occur when CMTS detects the SNR that goes below the threshold and either corr FEC or uncorr FEC is above the threshold. In this case, snrBelowThres and either corrFecAboveThres or uncorrFecAboveThres bits will get set. 2) Change from modulation profile 2 to modulation profile 1 would occur when CMTS detects the SNR goes above the threshold+3 and both corr FEC and uncorr FEC are below the threshold. In this case, snrAboveThres and corrFecBelowThres and uncorrFecBelowThres bits will get set. 3) Change in frequency or frequency hopping would occur when CMTS detects no active modem on the link. In this case, noActiveModem bit will get set accordingly. For the linecards that have the Hardware Based Spectrum Management capability, change in frequency, modulation or channel width occurs in the following criteria: 1) when CMTS detects the SNR or CNR goes below the threshold and either corr FEC or uncorr FEC is above the threshold. In this case, either snrBelowThres or cnrBelowThres and either corrFecAboveThres or uncorrFecAboveThres bits will get set. 2) when CMTS detects the SNR or CNR goes above the threshold + 3 and both corr FEC and uncorr FEC are below the threshold. In this case, either snrAboveThres or cnrAboveThres and both corrFecBelowThres and uncorrFecBelowThres bits will get set. 3) when CMTS detects no active modem on the link or uncorr FEC is above ccsUpSpecMgmtFecUnCorrectThres2. In this case noActiveModem or uncorrFecAboveSecondThres bit will get set accordingly. Note: The order of frequency, modulation or channel width changes for the advanced spectrum management linecards will be determined based on the selection of the ccsUpSpecMgmtHopPriority.
