clear qos
To clear the global and per-interface aggregate QoS counters, use the clear qos command.
clear qos [aggregate-policer [name] | interface {{fastethernet | GigabitEthernet}
{mod/interface}} | vlan {vlan_num} | port-channel {number}]
Syntax Description
Defaults This command has no default settings.
Command Modes Privileged EXEC mode
Command History
Usage Guidelines This command is not supported on the Supervisor Engine 6-E and the Catalyst 4900M chassis.
Note When you enter the clear qos command, the way that the counters work is affected and the 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 the global and per-interface aggregate QoS counters for all the
protocols:
Switch# clear qos
