Parameter
outbound : Performs RED operation on the sent packets.
acl-rule : Applied ACL rules which can be the combination of various ACL rules. For the
ways of combining ACLs and the description on related parameters, refer to Table 1-4
and Table 1-6.
system-index : Specifies an interior index value which is used when an ACL rule is
applied to the port. The index value ranges from 0 to 4294,967,295. This keyword is
only available when the ACL rule number is specified in the command. After the
specified ACL takes effect, there are three scenarios when you input the index value:
z
If you do not input an index value or the index value you input is 0, the system will
automatically assign an index whose value is greater than 0;
z
If the input index value is not 0 and does not conflict with the interior index used by
the system, the system will adopt the index value input by you;
z
If the input index value is not 0 but conflicts with the interior index used by the
system, the system will reassign an index value.
When the specified ACL rule is not effective, the system will adopt the index value input
by you.
qstart : Queue length where the system starts to drop packets at random, in the range of
0 to 262,128 in kbyte. The packets in the queue whose length is less than the qstart
argument will not be dropped. The value must be the multiples of 16 KB.
qstop : Queue length where the system stops dropping of packets at random, in the
range of 0 to 262,128 in kbyte. All the packets in the queue whose length is greater than
the
qstop argument will be dropped. The value must be the multiples of 16 KB.
probability : Drop probability when the qstop argument is reached, in the range of 0% to
100%.
Description
Use the traffic-red command to enable the RED operation and set RED parameters.
Use the undo traffic-red command to remove the RED configuration.
Note that the qstop argument in this command must be no smaller than the qstart
argument.
