Command Manual - QoS/ACL
Quidway S3500 Series Ethernet Switches
rule rule: Specifies the rule in the ACL to be activated, ranging from 0 to 127. If it is
not specified, all the rules in the ACL will be activated.
auto: Auto-allocates service groups by the switch.
remark-policed-service: Reallocates service groups.
trust-dscp: Reallocates service groups based on packet DSCP values.
dscp dscp-value: Reallocates service groups based on user-defined DSCP values.
dscp-value ranges 0~63.
untrusted dscp dscp-value cos cos-value local-precedence local-precedence
drop-priority drop-level: User-defines a set of service groups. dscp-value is DSCP
value, in digit (0~63) or name; local-precedence is local precedence value, in digit (0~7)
or name. cos-value is 802.1p priority value, in digits (0~7) or name; drop-level is
conform-level, in digit (0~2).
Description
Using the traffic-priority command, you can enable the ACL and configure traffic
classification and choose a set of service groups for the target traffics (only available to
the permitted rules in the ACL). Using the undo traffic-priority command, you can
cancel service groups for a designated traffic type.
The following modes are available in configuration service groups for a designated
traffic type:
1) The switch allocates service groups when it receives packets. You just select the
auto keyword in the command, for this mode.
2) Choose service groups for packets based on their DSCP values and
conform-levels and get them from "DSCP + Conform-Level → Service group"
mapping table. You just select the remark-policed-service trust-dscp keyword
in the command, for this mode.
3) Choose service groups for packets based on user-defined DSCP values and
conform-levels and get them from "DSCP + Conform-Level → Service group"
mapping table. You just select the remark-policed-service dscp dscp-value
parameter in the command, for this mode.
4) Customize a set of service groups. You just select the remark-policed-service
untrusted dscp dscp-value cos cos-value local-precedence local-precedence
drop-priority drop-level parameter in the command, for this mode.
If you want to choose the second or third mode, you must ensure you have configured
"DSCP + Conform-Level → Service group mapping table. For more information about
this mapping table, see the qos conform-level and dscp commands. In DSCP +
conform-level to service map used by packet priority remark function, the conform-level
equal 0.
