vismVADTolerance
Module: CISCO-VISM-MODULE-MIB
OID (symbolic): CISCO-VISM-MODULE-MIB::vismVADTolerance
OID (numeric): 1.3.6.1.4.1.351.110.3.17.4.22
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The value in this object refers to the customer accepted drop rate for voice connections when the bandwidth usage exceeds allowed value.
The actual range of this object is 0.0001% - 1.00 %
The unit is in percentage, since the default is 0.01 %, and since we cannot express such fractions in MIB , it is being multiplied by 10000 .
However, when the underlying CAC module is notified of the change in this object, then the value has to be divided by a factor of 10000.
Multiplication factor 10000 is picked as someone might be interested in a tolerance as low as 0.0001%.
This object will be applicable in case of AAL2 SVCs where the user does not add a PVC and also this object will be applicable if the per PVC level object vismChanVADTolerance(defined in CISCO-VISM-CAC-MIB MIB) is configured to have a value of zero.
Configuring this object will not have any affect when card level CAC is disabled (vismCacEnable).
What is vismVADTolerance?
This read-write Integer32 (1-10000) encodes the customer-accepted voice packet drop rate under bandwidth pressure, expressed as a percentage scaled by 10000 because the true range is 0.0001% to 1.00%. An admin cares because this tolerance feeds the underlying CAC module's decisions about how aggressively to admit or clip voice connections when bandwidth usage exceeds allowed limits. For example, an operator wanting to allow a slightly higher drop rate during congestion would raise this value from the default of roughly 100 (0.01%) to a larger number within the 1-10000 range.
