The above counters are cleared by the clear counters command. The queue
sizes cannot be cleared as they are instantaneous
Example
This example shows Gi1/0/1 is suffering from congestion (Tx Queue high)
and is dropping packets, either due to WRED drops or due to exceeding the
internal buffer limits.

Field Description
Congestion drops
Packets dropped due to congestion. This includes packets
that exceeded an upper WRED threshold and packet
dropped by WRED. ECN marked packets are not
counted as dropped.
Tx Queue
The instantaneous number of cells queued for egress on
the interface. Cells are 208 bytes.
Rx Queue
The instantaneous number of cells queued for ingress on
the switch. Cells are 208 bytes. If a port is configured for
PFC, cells are buffered on ingress. If not, cells are
buffered on egress.
Color drops
The number of packets dropped due to WRED dropping
of packets. Packets exceeding the upper WRED
threshold are counted in the drops bucket. ECN marked
packets are not counted as dropped.
WRED TX Queue
The instantaneous number of packets queued for
transmission on the interface as smoothed by the
exponential weighting function.
