The system can set service parameters for the matched traffic in one of following 
modes:

1 Employ the service parameters automatically allocated by the switch. Upon 

receiving a packet, the switch allocates a set of service parameters for it according 
to a specific rule. To choose this mode, you should select the auto keyword in this 
command.

2 Choose service parameters from the "DSCP + Conform-Level -> 

Service-parameter" mapping table according to packet DSCP value and conform 
level. To choose this mode, you should select the remark-policed-service 
trust-dscp keyword in this command.

3 Choose service parameters from the " DSCP + Conform-Level -> 

Service-parameter " mapping table or " EXP + Conform-Level -> 
Service-parameter " mapping table according to user’s DSCP priority or EXP value 
of MPLS packets and packet conform level. To choose this mode, you should select 
the remark-policed-service dscp dscp-value parameter in this command.

4 Customize a set of service parameters. To choose this mode, you should select the 

remark-policed-service untrusted dscp dscp-value cos cos-value 
local-precedence local-precedence drop-priority drop-level parameter in this 
command.

The "DSCP + Conform-Level -> Service-parameter" mapping table and " EXP + 
Conform-Level -> Service-parameter " mapping table here is that for the 
conform level 0.

■

Before selecting the second or third mode, you should make sure that you have 
configured the "DSCP + Conform-Level -> Service-parameter" mapping table 
and " EXP + Conform-Level -> Service-parameter " mapping table. For more 
information about this mapping table, see the qos conform-level, dscp and 
exp commands.
