csqIfDropConfigMinWredThreshold
Cisco Switch QOS If Dropped Config Minimum Wred Threshold
1.3.6.1.4.1.9.9.580.1.4.4.1.6
This object specifies the min WRED threshold parameter of a threshold number for the specific interface when WRED drop algorithm is used. WRED (Weighted Random Early Detect) is a mechanism which drops packets fairly during congestion so that adaptive applications can react to congestion. This object specifies a percentage of the buffer size. This object is configurable only if 'wred' bit in the value of qosIfCapabilities object for the same ifIndex and traffic direction is set. If value of csqIfDropConfigAlgorithm is not 'wred', this object value has no effect.
