Configuration Guidelines
• This feature must be configured globally for a router; 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.
• The cpu traffic qos dscp global configuration command configures IP-DSCP marking for
CPU-generated IP traffic by using either a specific DSCP value or a table map, but not both. A new
configuration overwrites the existing configuration.
• The cpu traffic qos precedence global configuration command configures IP-precedence marking
for CPU-generated IP traffic by using either a specific precedence value or a table map, but not both.
A new configuration overwrites the existing configuration.
• The cpu traffic qos dscp and cpu traffic qos precedence global configuration commands are
mutually exclusive. A new configuration overwrites the existing configuration.
• When the cpu traffic qos dscp global configuration command is configured with table maps, you
can configure only one map from value at a time—DSCP, precedence, or CoS. A new configuration
overwrites the existing configuration. Packets marked by this command can be classified and queued
by an output policy map based on the marked DSCP or precedence value.
• When the cpu traffic qos precedence global configuration command is configured with table maps,
you can configure only one map from value at a time—DSCP, precedence, or CoS. A new
configuration overwrites the existing configuration. Packets marked by this command can be
classified and queued by an output policy map based on the marked precedence or DSCP value.
• You cannot configure a map from value of both DSCP and precedence. 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.
• If the cpu traffic qos cos global configuration command is configured with only a map from value
of DSCP or precedence:
