Usage Guidelines

Usage Scenario

The mapping between the user priority, the CoS, and the packet color takes effect only after the user-priority command is configured in the AAA domain (specifying the priority of user traffic) and the DS domain that is configured with the user-priority phb command is applied to a AAA domain or BAS interface.

**Table1 ** Default mapping between the user priority, CoS and packet color

User Priority	CoS	Color
0	BE	green
1	AF1	green
2	AF2	green
3	AF3	green
4	AF4	green
5	EF	green
6	CS6	green
7	CS7	green

Example

# Set the CoS that corresponds to user priority 2 to AF1 and mark the packets in green.
