cpu traffic qos
cpu traffic qos
Use the cpu traffic qos global configuration command to configure the quality of service (QoS) marking
parameters for CPU-generated traffic. Use the no form of this command to return to the default setting.
cpu traffic qos [cos value | dscp value | precedence value | qos-group value]
no cpu traffic qos [cos value | dscp value | precedence value | qos-group value]
Syntax Description
Defaults The default egress queue value is 2. However, if there is no output policy attached to the port, the
CPU-generated traffic is sent through the first non-priority queue defined in the output policy map.
Command Modes Global configuration
Command History
Usage Guidelines Use the cpu traffic qos global configuration command to mark the control plane traffic that the CPU
generates.
You must globally enable mls qos global configuration command on the switch to use the cpu traffic
qos feature.
When you mark CPU-generated traffic with CoS, DSCP, IP precedence, or group values, the control
protocol traffic is marked with these values, except for Connectivity Fault Management (CFM) traffic and
Cisco IOS IP Service Level Agreements (SLAs). Any changes that you make using the cpu traffic qos
global configuration command does not affect the CFM traffic or IP SLA CoS markings.
Examples This example shows how to set the CoS value to 5, for the control plane traffic that the CPU generates.
Switch(config)# cpu traffic qos cos 5
You can verify your settings by entering the show cpu traffic qos privileged EXEC command.
cos value (Optional) Set the class of service (CoS) value.The range is from 0 to 7.
dscp value (Optional) Set the Differentiated Services Code Point (DSCP) value. The range is
from 0 to 63. You also can enter a mnemonic name for a commonly used value.
precedence
value
(Optional) Set the parameters for each IP precedence value. The range is from 0 to
7. You also can enter a mnemonic name for a commonly used value.
qos-group value (Optional) Set the parameters for each quality-of-service (QoS) group value. The
range is from 0 to 99.
