Command Manual – QoS/ACL
Quidway S8500 Series Routing Switches
acl-number: Sequence number of the ACL, ranging from 2000 to 3999. acl-name:
Name of the ACL, a string beginning with character a-z or A-Z. Note that this argument
cannot contain spaces or quotation marks.
rule rule: Specifies the rule identified by the rule argument of the ACL. The rule
argument ranges from 0 to 127. Without this keyword, this command applies to all rules
of the ACL.
system-index index: Specifies the system index value of the rule. Normally, an applied
rule is assigned a globally unique index value automatically for being indexed. You can
also specify the index value for the rule. In general, you are not recommended to
specify this parameter manually.
tc-index index: The traffic control index. If the same index is configured under different
flow rules when you configure the traffic policing, the total traffic of all these flows will be
limited by the configured flow policing parameters. For example, the cir value of the flow
of match rule 1 is configured to be 10kbps, and that of match rule 2 is configured to be
10kbps. The tc-index values of the two rules are the same at the same time. Then the
sum of the average rate of the flow matching rule 1 and the flow matching rule 2 will be
limited to 10kbps.
Note:
When you specifies the same tc-index value for different flows, the parameter settings
of the traffic policing action must be consistent completely; otherwise the system will
prompt errors; when the tc-index is set to 0, it means that the system will select the
index automatically.
cir: Committed information rate in Kbps.
cbs: Committed burst size in bytes.
ebs: Excess burst size in bytes.
pir: Peak information rate in Kbps.
remark-cos: Sets new 802.1p priority value for the packet according to its
conform-level and local precedence.
remark-drop-priority: Sets drop precedence value for the packet according to its
conform-level.
remark-policed-service: Sets new service parameters for the packet according to its
conform-level and DSCP priority value.
exceed: Optional parameter, used to set the action to be taken when traffic threshold is
exceeded.
forward: Forwards the packet.
