This attribute specifies the reduction of the maximum Cell Delay
Variation (CDV) of shaped transmit traffic.
When the value of this attribute is set to disabled, the CDV value
can be determined by the following equation:
CDV <= 2/ASR + 1/LS
where ASR is the Actual Shaping Rate of the connection and LS is
the Link Speed of the interface.
When the value of this attribute is set to enabled, the CDV
relationship changes to the following equation:
CDV <= 1/ASR + 1/LS
As can be noted from the equations above, setting this attribute to
enabled can reduce the CDV significantly. CDV reduction may be
used to conform to policers which have strict Cell Delay Variance
Tolerance (CDVT). However using this function reduces the
transmit bandwidth utilization of the following cards: 3pDS3Atm,
3pOC3Atm, 2pJ6MAtm.
When the value is cardDependent, CDV reduction is disabled for
cardtypes 3pDS3Atm, 3pOC3Atm, 2pJ6MAtm, 4pDS1Aal1,
4pE1Aal1 and enabled for all other cards.
