The tmnxOtuIfRowStatus controls the creation and deletion of row
entries in the tmnxOtuIfTable.
Creating a row in the tmnxOtuIfTable using 'createAndGo (4)' enables
OTU encapsulation for the interface. Deleting the row using
'destroy (6)' will disable the OTU encapsulation.
If a physical port does not support the OTU encapsulation, an attempt
to set the tmnxOtuIfRowStatus to a value of 'createAndGo (4)' will
fail with an inconsistent value result.
