QOS
In addition to the QOS parameter on the ETH N standard parameters pages (which are used to
enable quality of service management for that ETH instance), each ETH instance has an associated
QOS instance (ETH 0 maps to QOS 5, ETH 1 maps to QOS 6, etc.). These QOS instances include
10 QOS queues into which packets may be placed when using QOS. Each of these queues must be
assigned a queue pro
fi
le (from the twelve available pro
fi
les de
fi
ned in the
Confi gure
>
Quality of
Service
>
Q Profi le
pages), and a priority value.
Using the Web Page(s)
Each
ETH n
>
QOS
page includes the
Link speed
parameter at the top followed by a list of queues
with drop-down selection boxes that are used to assign a pro
fi
le and a priority to each queue.
Link speed (Kbps):
This parameter should be set to the maximum data rate that this PPP link is capable of sustaining. It
is used when calculating whether or not the data rate from a queue may exceed its Minimum Kbps
setting (as determined by the pro
fi
le assigned to it) and send at a higher rate (up to the Maximum
Kbps setting).
Queue priorities:
Below this heading is a list of the queues from 0 to 9 alongside each of which are drop down selection
lists for assigning pro
fi
le numbers (from 0 to 11) and queue priorities. The priority may be set to “Very
High”, “High”, “Medium”, “Low” or “Very Low”.
Using Text Commands
From the command line, use the
qos
command to assign pro
fi
les and priorities to each of the queues
relating to a PPP instance. To display a list of the pro
fi
les assigned to the queues belonging to a QOS
instance, enter the following command:
qos <instance> ?
where
<instance>
is the QOS instance number.
To assign a pro
fi
le to a queue for a QOS instance, use the command in the format:
qos <instance> parameter <value>
