Usage
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.
