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, but this value may
change while the system is running. 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.
traffic-index traffic index : Traffic index value. Quote the traffic parameters
through traffic-index . These traffic parameters are configured with the
traffic-params command.
n
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.
drop : Drops the packet.
Description
Use the traffic-limit command to activate ACL flow identification to perform flow
limit for the matching data flow in the VLAN and perform different actions on the
packets within the flow limit and those beyond the flow limit.
Use the undo traffic-limit command to undo the flow limit.
