| Description | An HE operation entry to instruct a Subscriber-unit to move
to a new downstream and/or upstream channel.
There can be more than one entry per Subscriber-unit,
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 HE has generated
downstream frequency and/or upstream channel override fields
in the RNG-RSP message sent to a Subscriber-unit or time out.
In either case, the operation is completed. During this
time the row cannot be destroyed.
Once the operation is completed, the real result of the
operation to the Subscriber-unit cannot be known from this table.
The result of the Subscriber-unit's downstream frequency and the
upstream channel id can be checked from other MIB tables.
For example, cwdIfHeServiceTable from
CISCO-WIRELESS-DOCS-IF-MIB can be used to check
whether the Subscriber-unit's downstream frequency
and upstream channel id are changed. Please note that even
though HE has generated downstream frequency and/or
upstream channel override fields in the RNG-RSP message sent
to a SUs if the SU cannot lock at 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 cwdxHeSuChOverState
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. |
