| Description | A OAM loopback request entry.
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 NMS should
then create the associated instance of the row status
and row owner objects. It must also, either in the same
or in successive PDUs, create the associated instances
specifying the VPI and VCI values. It should also modify
the default values for the other configuration objects
if the defaults are not appropriate.
Once the appropriate instance of all the configuration
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 request. 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 configuration objects.
Once the OAM sequence has been activated, it cannot be
stopped -- it will run until the configured number of
cells have been sent.
Once the sequence completes, the management station should
retrieve the values of the status 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 5 minutes of
completing. |
