Information
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.
