Configure a mark map

An example of how to create a mark map. A mark map can modify the PCP value written into the L2 frame header immediately prior to transmission of the packet.

Create a mark map that sets the PCP value in the L2 frame of packets that have a certain set of DSCP values.
```
user@system# set policy qos mark-map mark-map-1 dscp-group grp-0-to-15 pcp-mark 3
```
The mark map called mark-map-1 states that packets with a DSCP value that belong to the DSCP group called grp-0-to-15 will have the PCP value in their L2 frame set to 3.
Add more entries to the mark map, but with a different set of DSCP values, and a different PCP value.
```
user@system# set policy qos mark-map mark-map-1 dscp-group grp-16-to-63 pcp-mark 5
```
The mark map called mark-map-1 states that packets with a DSCP value that belongs to the DSCP group called grp-16-to-63 will have the PCP value in their L2 frame set to 5.
Attach the mark map to the QoS policy called policy-1.
```
user@system# set policy qos name policy-1 shaper mark-map mark-map-1
```
The mark map called mark-map-1 defines how packets that pass through the QoS policy called policy-1 get the PCP value in the L2 frame set.

Attach the policy to a dataplane interface.

For platforms in router mode:

user@system# set interfaces dataplane dp0s3 policy qos policy-1

For platforms in switch mode:

user@system# set interfaces dataplane dp0ce10 switch-group port-parameters policy qos policy-1

The mark map is now configured.
