Object
column
SNMPv2-SMIUnsigned32
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.
