QoS Configuration
5. Configure QoS mapping
Command Explanation
Global Mode
mls qos map (cos-dp <dp1..dp8> | dscp-dscp <in-dscp
list> to <out-dscp> | dscp-intp <in-dscp list> to <intp> |
dscp-dp <in-dscp list> to <dp> )
no mls qos map (cos-dp | dscp-dscp | dscp-intp | dscp-
dp)
mls qos map intp-dscp <dscp1..dscp8>
no mls qos map intp-dscp Set the priority mapping for QoS,
the no command restores the default
mapping value.
6. Clear accounting data of the specific ports or VLANs
Command Explanation
Admin Mode
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
Admin 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 | queu-
ing] | vlan <vlan-id> }
Displays QoS configuration information on a port.
26.3 QoS Example
Example 1:
Enable QoS function, change the queue out weight of port ethernet 1/0/1 to 1:1:2:2:4:4:8:8, set
the port in trust CoS mode without changing DSCP value, and set the default CoS value of the
port to 5. The configuration steps are listed below:
Switch#config
Switch(config)#interface ethernet 1/0/1
Switch(Config-If-Ethernet1/0/1)#mls qos queue weight 1 1 2 2 4 4 8 8
Switch(Config-If-Ethernet1/0/1)#mls qos cos 5
Configuration result:
