The user could configure this number according to the number of
downstreams and the number of modem line cards in the CMTS.
The number can range from 1 to 8191. The default value is 100.
When the number of modems exceeds the max flap list size,

ranges, reboots, and ends when it starts initial maintenance again.
If the interval of time is less than what is specified in
flapInsertionTime, the flapCmInsertionFails and cmFlapCounts
will increment.
The valid range is from 1 to 86400 seconds. The default value is 60. |

1.3.6.1.4.1.4981.6.1.1.1.1.6 |
| Specifies the maximum threshold for the number of consecutive miss
counts during a polling cycle. If the flap miss counts goes over
this threshold, the modem will be added into the flap list.
Polling is maintained between the CMTS and the cable modem
every 10 seconds. The flapMissThreshold specifies the maximum
number of consecutive missed counts during one station maintenance
poll interval. If there are more than 16 consecutive miss counts
during one polling cycle, the modem will de-insert and attempt to
range again.
The value ranges from 1 to 12 consecutive counts.
The default value is 6. |

1.3.6.1.4.1.4981.6.1.1.1.1.7 |
| The power adjustment threshold for a CM
to raise and lower it's transmit power during
normal operation.
When a modem's power adjustment goes above or below
the flapPowerAdjThreshold the CM will be added into
the flap list. The flapCmPowerAdjustments and cmFlapCounts
will be incremented as well.
flapPowerAdjThreshold values of 2 dB and below are low
enough to continuously increment the flapCmPowerAdjustments
under normal conditions.
The values range from 1 to 10. The default is 2. |

from the Cable Modem. The CMTS can check up to 16 consecutive
times for a ranging request message during one polling cycle.
Misses are not desirable since this is usually an
indication of a return path problem; however,
having a small number of misses is normal.
Ideally, the Hit should be much greater than the Miss counts. |

| cmFlapRowStatus |
1.3.6.1.4.1.4981.6.1.1.2.1.13 |

When a new flap cable modem is detected, and does
not exist in flap list and
flapListCurrentSize is less than flapListMaxSize,
an entry will be created in this table.
The 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 if they are aged out.
The age out time is defined in flapAgingOutTime
When a row is set to destroy(6), it will remove the entry
immediately.
To prevent an entry from being aged out, the entry should be
set to notInService(2). The entry will remain in the table
until this instance is set to destroy.
The user is allowed set an entry from active to notInService
or from notInService to destroy
A user is not allowed to change a notInService entry to active.
createAndGo(4) and createAndWait(5) are not supported. |

This is a place holder for the reason parameter for the modem to go
into flap list. This should return ZERO when read. This just allows us
to include a flapping reason in the modem flap trap varbind.
