This counter tracks the lower 32 bits of egress queue group packets that were in-profile but dropped at the network port due to queue congestion or policy enforcement on a Timetra SROS device. Network operators examine this metric to detect when in-profile traffic is being discarded, which may indicate insufficient queue buffers or QoS policy misconfigurations. This is part of a 64-bit counter pair used on systems with large packet volumes that exceed 32-bit counter capacity.
