Class of Service Queues (cosq) egress drop statistics are counted against both Drops In and Drops Out interface statistics.
Any CoS queue egress drop is also counted against ingress drop stats, which could be interpreted incorrectly as doubled total drop stats.
This occurs for all cosq drops in response to excess egress traffic and MMU egress congestion.
None.
The Drops In interface statistics no longer includes Class of Service Queues (cosq) egress drop counts, which is correct behavior.
