DESCRIPTION
You can use the queue component to configure a custom queuing method.
EXAMPLES
create queue my_q type pfifo
Creates a pfifo type queue name my_q.
list queue all-properties
Displays all of the properties of all of the queue.
OPTIONS
app-service
Specifies the name of the application service to which the object belongs. The default value is none.
Note: If the strict-updates option is enabled on the application service that owns the object, you cannot
modify or delete the object. Only the application service can modify or delete the object.
description
User defined description.
glob Displays the items that match the glob expression. See help glob for a description of glob expression
syntax.
name Specifies a unique name for the component. This option is required for the commands create, delete, and
modify.
pfifo-max-size
Specifies the size of the largest queue for the pfifo type only. The default value is 0 (zero). Valid
units are bytes(default), eb, gb, k, kb, mb, pb, and tb.
pfifo-min-size
Specifies the size of the smallest queue for the pfifo type only. The default value is 0 (zero). Valid
units are bytes(default), eb, gb, k, kb, mb, pb, and tb.
regex
Displays the items that match the regular expression. The regular expression must be preceded by an at
sign (@[regular expression]) to indicate that the identifier is a regular expression. See help regex for
a description of regular expression syntax.
sfq-bucket-count
Specifies the number of buckets into which the queue is divided when you are configuring the sfq type.
Valid values are 0, 16, 32, 64, 128, 256, 512, and 1024. The default value is 0 (zero).
sfq-bucket-size
Specifies the bucket size for the sfq type. The default value is 0 (zero). Valid units are
bytes(default), eb, gb, k, kb, mb, pb, and tb.
sfq-perturbation
Specifies the interval in seconds at which the system reconfigures the SFQ hash function. This option
applies only to the sfq type. The default value is 0 (zero).
type Specifies the queue discipline this custom queue uses. The options are:
pfifo
The Priority FIFO queuing method queues all traffic under a set of five sub-queues based on the Type
of Service (TOS) field of the traffic. Four of the sub-queues correspond to the four possible TOS
values (Minimum delay, Maximum throughput, Maximum reliability, and Minimum cost). The fifth sub-
queue represents traffic with no TOS value. The Priority FIFO method processes these five sub-queues
in a way that preserves the meaning of the TOS value as much as possible. For example, a packet with
the TOS value of Minimum cost might yield dequeuing to a packet with the TOS value of Minimum delay.
sfq Stochastic Fair Queuing is a queuing method that further queues packets under a set of many FIFO
sub-queues. Selecting a specific sub-queue is based on a hash of the flow address information. SFQ
dequeues packets from the set of sub-queues in a Round Robin fashion. The overall effect is that
fairness of dequeuing is achieved, because packets from one flow cannot occupy the queues at the
exclusion of those of another flow.
