Usage Guidelines
Note When you enter the clear qos command, the way that the counters work is affected and traffic that is
normally restricted could be forwarded for a short period of time.
The clear qos command resets the interface QoS policy counters. If no interface is specified, the clear
qos command resets the QoS policy counters for all interfaces.
Examples This example shows how to clear global and per-interface aggregate QoS counters for all protocols:
Switch# clear qos
