Parameter
inbound: Sets traffic limitation for the inbound packets at the port.
ip-group { acl-number | acl-name }: Activates IP ACLs, including basic and advanced
ACLs. acl-number : Sequence number of ACL, ranging from 2000 to 3999. acl-name:
Name of the ACL, which must be a character string starting with an English letter (a-z or
A-Z), and without any space or quotation mark in it.
link-group { acl-number | acl-name }: Activates Layer 2 ACLs. acl-number: Sequence
number of ACL, ranging from 4000 to 4999. acl-name: Name of ACL, which must be a
character string started with an English letter (a-z or A-Z), and without any space or
quotation mark in it.
rule rule: Specifies the subitem of an active ACL, ranging from 0 to 127; if not specified,
all subitems of ACL will be activated.
system-index index here is the system index for an ACL rule. When delivering a rule,
the system assigns a globally unique index to it, for convenience of later retrieval. You
can also assign a system index for it when delivering an ACL rule with this command.
However, you are not recommended to manually assign a system index if not urgently
necessary..
tc-index index: Index value of traffic conditioner, ranging from 0 to 12288. If you
configured the same index value to different traffic rules during traffic policy
configuration, then the sum of these traffics is restricted by the configured traffic policy
parameter. For example, configure cir of the traffic that matches rule 1 to 10 kbps, and
that of the rule 2 to 10 kbps too; and both of the rules have the same index value of
traffic conditioner, then the sum of the average rates of rule 1 and rule 2 is restricted to
10 kbps.
Note:
The parameters of traffic policy must be the same if you configure the same tc-index
for different traffic; otherwise the system prompts you for the wrong configuration;
when the tc-index is 0, it means that the system will select an index value
automatically.
If you remove the card with QoS/ACL configured when the system operates, the
corresponding system index value is automatically released and is then used for a
newly delivered flow rule. Once the system index value is occupied, the original
configuration cannot be restored even you insert the removed card back.
