cir
: Committed information rate in Kbps.
cbs
: Committed burst size in bytes.
ebs
: Excess burst size in bytes.
pir
: Peak information rate in Kbps.
conform: Optional parameter used to set the action to be taken when the traffic does
not exceed the set value.
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 value.
exceed
: Optional parameter to set action for the case when traffic threshold is
exceeded.
z
forward: Forwards the packet.

Description
Use the
traffic-limit
command to activate an ACL and set traffic limitation to take
different actions for the packets within and beyond the preset traffic threshold.
Use the
undo traffic-limit
command to remove traffic limitation setting.
This command is only applicable to the packets which match the permitted rules in the
ACL.
It is required that CIR is less than or equal to PIR and CBS is less than or equal to EBS.
You are recommended to configure CBS and EBS to numbers that are 100 to 150 times
of CIR.
For the same traffic, you cannot select both the
remark-cos
and
remark-policed-service
keywords, or both the
remark-drop-priority
and
remark-policed-service
keywords.
Before selecting the
remark-policed-service
keyword, you must make sure you have
configured the DSCP + Conform-Level
—
> Service parameter mapping table. Before
selecting the
remark-cos
keyword, you must ensure you have configured the
Local-prec Conform-level
—
> 802.1p priority mapping table. For details about
the two mapping tables, see the
qos
conform-level
,
dscp
and
local-precedence
commands.
