Command Manual – QoS/ACL
Quidway S8500 Series Routing Switches
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.
Choose service parameters from the "DSCP + Conform-Level — >
2)
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.
Choose service parameters from the " DSCP + Conform-Level — >
3)
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
local-precedence local-precedence drop-priority drop-level parameter when
executing this command.
Note:
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.
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.
