1.4.2 Configuring Priority Mapping
You can modify the CoS-precedence-to-local-precedence,
DSCP-precedence-to-local-precedence and IP-precedence-to-local-precedence
mapping tables as required to mark packets with different priorities.
I. Configuration prerequisites
The target CoS-precedence-to-local-precedence,
DSCP-precedence-to-local-precedence and IP-precedence-to-local-precedence
mapping tables are determined.
II. Configuration procedure
