This attribute specifies the default of whether to force tagging
(CLP=1) of all cells for all rt-VBR connections. An override to this
default may be specified for a provisioned connection under the Vcd
Tm or Vpd Tm component.
When this attribute is set to enabled, CLP is set to 1 for all cells in
the transmit direction. Force tagging is only supported on ATM IP
FPs.
On CQC-based ATM FPs, this attribute must be set to disabled.
When this attribute is set to disabled, CLP is unchanged for all cells
in the transmit direction.
This attribute never applies to any type of Vpt.
