Configuring PFC3 Egress DSCP Mutation
These sections describe how to configure PFC3 egress DSCP mutation:

Configuring a DSCP Mutation Map
PFC3 supports 16 DSCP mutation maps. QoS uses one mutation map for the default mapping. You can
configure 15 mutation maps. The mutation maps define the internal DSCP-to-egress DSCP relationships.
To configure a DSCP mutation map, perform this task in privileged mode:
This example shows how to configure DSCP mutation map 1:
Console> (enable)
set qos dscp-mutation-map 1 30:2
QoS dscp-mutation-map with mutation-table-id 1 has been set correctly.
Console> (enable)
This example shows how to verify DSCP mutation map 1:
Console> (enable)
show qos maps config dscp-mutation-map 1
