The system can perform the following operations to the service parameters of the 
matched flow: 
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, specify the auto keyword when executing 
this command. 
2)  Choose service parameters from the “DSCP + Conform-Level — > 
Service-parameter” mapping table according to the DSCP priority and conform 
level of the packet. To choose this mode, specify the remark-policed-service 
trust-dscp keyword when executing this command. 
3)  Choose service parameters from the “ DSCP + Conform-Level — > 
Service-parameter ” mapping table and “EXP + Conform-Level — > 
Service-parameter ” mapping table according to Conform-Level and customized 
DSCP priorities and EXP values of MPLS packets. To choose this mode, specify 
the remark-policed-service dscp dscp-value when executing this command. 
4)  Specify a set of service parameters. To choose this mode, specify 
remark-policed-service untrusted dscp dscp-value cos cos-value 
local-precedence local-precedence drop-priority  drop-level parameter when 
executing this command. 
 
  Note: 
z  The “DSCP + Conform-Level —> Service-parameter” mapping table and “EXP + 
Conform-Level —> Service-parameter” mapping table here are mapping tables with 
the Conform-Level of 0. 
z  Before selecting the second or third mode listed above, make sure the “DSCP + 
Conform-Level —> Service-parameter” mapping table and “EXP + Conform-Level 
—> Service-parameter” mapping table already exist. For more information about 
these mapping tables, refer to the qos conform-level, dscp, and exp commands.
