cdxCmtsCmChOverEntry

A CMTS operation entry to instruct a cable modem to move to
a new downstream and/or upstream channel.
            
A CMTS operator can use this to initiate an operation
in CMTS to instruct a cable modem to move to a new
downstream, or upstream channel or both. 
            
Each entry consists of the mac address of the cable modem
to be moved, a new downstream frequency, a new upstream channel 
id etc..  More than one entries could have for a cable modem,
so there is a time stamp for each entry to show the time
when this operation is initiated. 
            
A management station wishing to create an entry should
first generate a pseudo-random serial number to be used
as the index to this sparse table.  The station should
then create the associated instance of the row status
object. It must also, either in the same or in successive
PDUs, create the associated instance of the command and
parameter objects. It should also modify the default values
for any of the parameter objects if the defaults are not
appropriate.
            
Once the appropriate instances of all the command
objects have been created, either by an explicit SNMP
set request or by default, the row status should be set
to active to initiate the operation. Note that this entire
procedure may be initiated via a single set request which
specifies a row status  of createAndGo as well as specifies
valid values for the non-defaulted parameter objects.
            
Once an operation has been activated, it cannot be stopped.
That is, it will run until either the CMTS has generated 
downstream frequency and/or upstream channel override fields 
in the RNG-RSP message sent to a cable modem or time out. 
In either case, the operation is completed.
            
Once the operation is completed, the real result of the 
operation to the cable modem cannot be known from this table.
The result of the cable modem's downstream frequency and the 
upstream channel id can be checked from other MIB tables.  
For example, docsIfCmtsServiceTable from DOCS-IF-MIB can be 
used to check whether the cable modem's downstream frequency
and upstream channel id are changed.  Please note that even
the CMTS has generated downstream frequency and/or upstream 
channel override fields in the RNG-RSP message sent to a 
cable modems, if the cable modem cannot lock the instructed 
downstream frequency or no upstream channel id could be used, 
it may reconnect back to the original downstream frequency
and upstream channel id. 
            
Once the operation completes, the management station should
retrieve the values of the cdxCmtsCmChOverState 
objects of interest, and should then delete the entry.  
In order to prevent old entries from clogging the table, 
entries will be aged out, but an entry will never be deleted 
within 15 minutes of completing.
