6. Clear accounting data of the specific ports or VLANs
Command
Explanation

clear mls qos statistics [interface
<interface-name> | vlan <vlan-id>]
Clear accounting data of the specified
ports or VLAN Policy Map. If there are no
parameters, clear accounting data of all
policy map.
7. Show configuration of QoS.
Command
Explanation
Interface Mode
show mls qos maps [cos-dp |dscp-dscp |
dscp-intp | dscp-dp | intp-dscp]
Display the configuration of QoS mapping.
show class-map [<class-map-name>]
Display the classified map information of
QoS.
show policy-map [<policy-map-name>]
Display the policy map information of
QoS.
show mls qos {interface [<interface-id>]
[policy | queuing] | vlan <vlan-id>}
Displays QoS configuration information on
a port.
13.3 QoS Example
Example 1:
Enable QoS function, change the queue out weight of port ethernet 1/1 to 1:1:2:2:4:4:8:8, and set the port in
trust QoS mode without changing DSCP value, and set the default QoS value of the port to 5.
The configuration steps are listed below:
Switch#config
Switch(config)#mls qos
Switch(config)#interface ethernet 1/1
Switch(Config-If-Ethernet1/1)#wrr-queue bandwidth 1:1:2:2:4:4:8:8
Switch(Config-If-Ethernet1/1)#mls qos trust cos
Switch(Config-If-Ethernet1/1)#mls qos cos 5
Configuration result:
When QoS enabled in Global Mode, the egress queue bandwidth proportion of port ethernet1/1 is
1:1:2:2:4:4:8:8. When packets have CoS value coming in through port ethernet1/1, it will be map to the queue
out according to the CoS value, CoS value 0 to 7 correspond to queue out 1, 2, 3, 4, 5, 6, 7, 8, respectively. If
