CONFIG Commands
Queue Configuration
Beginning with Firmware Version 7.7.4, the queuing characteristics of all “N” and “-02”
model Gateway’s WAN interface can now be configured for:
•
strict priority queuing (as currently)
•
weighted fair queuing
•
rate-limiting funnel
☛
Note:
The configuration mechanism is designed to be flexible enough to accommo-
date complex queuing requirements. Configurations not supported by the
Gateway will be flagged during configuration verification.
You configure the WAN outbound queue as follows:
•
create and configure one or more queues, which can be a basic queue or a priority
queue comprising a group of basic queues, a weighted fair queue comprising a group of
basic queues, or a funnel comprising a group of basic queues;
•
assign a queue instance to the Ethernet WAN interface;
•
map packet attributes to a queue.
The same queue name can be assigned to multiple interfaces which require identical
queue configuration, however currently the only interface available for queueing configura-
tion is ethernet 1.
To help you configure queues, and to maintain compatibility with previous firmware
releases, several queues are set up automatically on upgrade to Version 7.7, or upon a
factory reset.

set queue name
queue_name
option [ on | off ]
type [ basic | wfq | priority | funnel ]
Creates a queue named
queue_name
and assigns a
type
:
•
basic
– Basic Queue
•
wfq
– Weighted Fair Queue
•
priority
– Priority Queue
•
funnel
– Funnel Queue
Basic Queue
set queue name
basic_queue_name
option [ on | off ]
set queue name
basic_queue_name
type basic
Specifies the Basic Queue named
basic_queue_name
attributes. Basic queues have one
input and one output. The basic queue is assigned an ID, with the following attribute: when
the queue is full, discard.
By default, the following Basic Queues are created:
•
basic_q0
•
basic_q1
•
basic_q2
•
basic_q3

.
•
wf_queue_name
– name of weighted fair queue
A weighted fair queue can contain up to 8 input queues. For each input queue, the follow-
ing is configured:
•
weight-type
– the weighted fair queue configuration allows you to set the rate in bits
per second (
bps
) or percentage of the line rate (
relative
).
bps
is the default.
•
n
– entry number for this input queue
•
input_queue_name
– name of input queue
•
weight_value
– numeric relative weight of queue
•
share-bw
– if enabled, the bandwidth for this queue can be shared between other
queues when idle.
•
default-input
– specifies the default input queue name.
The default special queuing configuration shapes the rate of a custom flow toward the
Remote Management Server.
By default, the following WFQ is created:
set queue name "wfq" option on
set queue name "wfq" type wfq
set queue name "wfq" weight-type bps
set queue name "wfq" entry 1 input "basic_q0"
set queue name "wfq" entry 1 weight 10000
set queue name "wfq" entry 1 share-bw off
set queue name "wfq" entry 2 input "basic_q1"
set queue name "wfq" entry 2 weight 20000
set queue name "wfq" entry 2 share-bw off
set queue name "wfq" entry 3 input "basic_q2"

attributes.
•
priority_queue_name
– name of priority queue
•
input_queue_name
– name of input queue
•
priority_value
– numeric relative priority of queue. The higher the number, the higher
the priority of the queue.
•
default-input
– specifies the default input queue name.
By default, the following priority queue is created:
set queue name "pq" option on
set queue name "pq" type priority
set queue name "pq" entry 1 input "basic_q0"
set queue name "pq" entry 1 priority 10
set queue name "pq" entry 2 input "basic_q1"

set queue name "pq" entry 3 input "basic_q2"
set queue name "pq" entry 3 priority 30
set queue name "pq" entry 4 input "basic_q3"
set queue name "pq" entry 4 priority 40
set queue name "pq" default-input "basic_q0"
