Default Value
IP precedence 0 = DSCP 0
IP precedence 1 = DSCP 8
IP precedence 2 = DSCP 16
IP precedence 3 = DSCP 24
IP precedence 4 = DSCP 32
IP precedence 5 = DSCP 40
IP precedence 6 = DSCP 48
IP precedence 7 = DSCP 56
DSCP 0–7 = EXP 0
DSCP 8–15 = EXP 1
DSCP 16–23 = EXP 2
DSCP 24–31 = EXP 3
DSCP 32–39 = EXP 4
DSCP 40–47 = EXP 5
DSCP 48–55 = EXP 6
DSCP 56–63 = EXP 7
Marked-down DSCP value equals original DSCP value
(no mark down)
No mutation map by default
None
None
Label + EXP value
There are four possibilities at the MPLS core QoS:
Swapping—Incoming EXP field is copied to outgoing
•
EXP field.
• Swapping + imposition—Incoming EXP field is copied
to both the swapped EXP field and the imposed EXP
field.
If there is a service policy with a set for EXP field, its
Note
EXP field will be placed into the imposed label and
also into the swapped label.
Disposition of topmost label—Exposed EXP field is
•
preserved.
Disposition of only label—Exposed IP DSCP is
•
preserved.
Preserve the exposed IP DSCP
