Usage Guidelines
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
trust
keyword configures the switch to trust the incoming CoS, DSCP, or precedence value and mark
the packet according to the global map configuration.
precedence-value
Configure the precedence value. The range is from 0 to 7. If no precedence
value is configured, the protocol specific value for each packet applies.
Note
You can substitute the following keywords for the numbers 0 to 7:
•
routine (0)
•
priority (1)
•
immediate (2)
•
flash (3)
•
flash-override (4)
•
critical (5)
•
internet (6)
•
network (7)
trust
Configure the switch to trust the precedence value of the incoming packet.
precedence-mutation
mutation-map-name
Configure the switch to change the incoming precedence value based on the
configured mutation-map.
