Configuring Priority Mapping
You can modify the COS-precedence-to-other-precedence, DSCP-precedence-to-other-precedence,
and DSCP-precedence-to-DSCP-precedence mapping tables as required to mark packets with
different priorities.
Configuration prerequisites
The target COS-precedence-to-other-precedence, DSCP-precedence-to-other-precedence, and
DSCP-precedence-to-DSCP-precedence mapping tables are determined.
Configuration procedure
Follow these steps to configure the COS-precedence-to-other-precedence mapping table:
