E-Series Only Behavior
If a Policy QoS is applied on an interface when
clear qos statistics is issued, it will clear the
egress counters in
show queue statistics and vice versa. This behavior is due to the values
being read from the same hardware registers.
The
clear qos statistics command clears both the queued and matched byte and packet
counters if the queued counters incremented based on classification of packets to the queues
because of policy-based QoS. If the queued counters were incremented because of some other
reason and do not reflect a matching QoS entry in CAM, then this command clears the
matched byte and packet counters only.
