cpu traffic qos cos
cpu traffic qos cos
Use the cpu traffic qos cos command in global configuration mode to configure quality of service (QoS)
marking based on class of service (CoS) for control plane traffic. To return to the default value, use the
no form of this command.
cpu traffic qos cos {cos_value | cos [table-map table-map-name] | dscp [table-map
table-map-name] | precedence [table-map table-map-name]}
no cpu traffic qos cos {cos_value | cos [table-map table-map-name] | dscp [table-map
table-map-name] | precedence [table-map table-map-name]}
Syntax Description
Command Default Control plane (CPU) traffic is not marked for QoS.
Command Modes Global configuration
Command History
Usage Guidelines Configure any desired table-maps before configuring marking or queuing of CPU traffic.
This feature must be configured globally for a switch; it cannot be configured per-port or per-protocol.
Enter each cpu traffic qos marking action on a separate line.
The cpu traffic qos cos global configuration command configures CoS marking for CPU-generated
traffic by using either a specific CoS value or a table map, but not both. A new configuration overwrites
the existing configuration.
When the cpu traffic qos cos global configuration command is configured with table maps, you can
configure two map from values at a time—CoS and either DSCP or precedence.
cos-value Specify a CoS value. The range is from 0 to 7. If no CoS value is configured,
the protocol-specific default value for each packet is applied.
cos Configure the CoS value based on the CoS value in the packet, using a
table-map.
table-map
table-map-name
Specify the table-map to use for marking the CPU traffic CoS based on the
CoS value in the packet.
dscp Configure the CoS value based on the DSCP value in the packet using a
table-map.
table-map
table-map-name
Specify the table-map to use for marking the CPU traffic CoS based on the
DSCP value in the packet.
precedence Configure the precedence value. The range is from 0 to 7.
table-map
table-map-name
Specify the table-map to use for marking the CPU traffic CoS based on the
IP-precedence value in the packet.
