Parameter
inbound: Performs traffic limitation to the packets received by the interface.
outbound: Performs traffic limitation to the packets sent by the interface.
ip-group { acl-number | acl-name } [ rule rule ]: the basic or advanced ACLs;
acl-number: the sequence number of ACLs, ranging from 2000~3999; acl-number: the
name of ACLs, character string, which must be started with an English letter (i.e., a-z or
A-Z), and there should not be a space or quotation mark in it; rule rule: (Optional)
specifies a subitem of an ACL, ranging from 0 to 127, it represents all the subitems of
the ACL if not specified.
link-group { acl-number | acl-name } [ rule rule ]: The Layer 2 ACL; acl-number: the
sequence number of an ACL, ranging from 4000~4999; acl-name: the name of an ACL,
character string, which must be started with an English letter (i.e., a-z or A-Z), and there
should not be a space or quotation mark in it; rule rule: (Optional) specifies the subitem
of an ACL, ranging from 0 to 127, it represents all the subitems of the ACL if not
specified.
user-group { acl-number | acl-name }: activate the user-defined ACL. acl-number:
Specifies the ACL number, ranging from 5000 to 5999. acl-name: Specifies the ACL
name with a character string started with English letters (that is [a to z, A to Z]),
excluding space and quotation marks.
kbps: Specifies the traffic limit to kbps. In this approach, the rate is in kbps and the
granularity can be as low as 64 kbps.
target-rate: The set normal traffic, as for the LS82GP20 and LS82GT20 interface cards,
the value ranges from 1 to 1000, in Mbps; as for other types of interface cards, the unit
is kpbs, the value ranges from 64 to 8388608 and must be the multiple of 64k.
exceed action: (Optional) The action taken when the traffic exceeds the threshold. Only
LS82GP20 and LS82GT20 interface cards support this parameter. The action can be:
z drop: Drops the packets.
z remark-dscp value: Sets new DSCP value.
Description
Using the traffic-limit command, you can activate ACL and perform traffic limitation.
Using the undo traffic-limit command, you can remove traffic limitation.
This command performs traffic limitation to the packets that match with specified ACL
rule, and is only effective to the permit rule.
