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.
