– CIR value shows the link tier
– Maximum queue-depth shows historic record of the queuee. If this number is close to Queue-limit or it grater than any of the minimum or maximum WRED thresholds, this could be sign of excessive congestion which could have resulted in packets getting dropped.
– Randomm Drops show the number of packets that were droppeed by WRED between the minimum and maximum WRED thresholds.
– Threshold Drops show the drops that have happened due to the length of the queeue having exceeded the maximum WRED threshold.
