Cpu Traffic Qos Cos - Cisco ME 3400 Command Reference Manual

Chapter 2 Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands

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.
Syntax Description cos-value
cos
table-map
table-map-name
dscp
table-map

Command Default
Control plane (CPU) traffic is not marked for QoS.
Command Modes
Global configuration
Command History Release

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.

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]}
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.
Configure the CoS value based on the CoS value in the packet, using a
table-map.
Specify the table-map to use for marking the CPU traffic CoS based on the
CoS value in the packet.
Configure the CoS value based on the DSCP value in the packet using a
table-map.
Specify the table-map to use for marking the CPU traffic CoS based on the
DSCP value in the packet.
Configure the precedence value. The range is from 0 to 7.
Specify the table-map to use for marking the CPU traffic CoS based on the
IP-precedence value in the packet.
