To access the Policy Flow Form, select QoS -> Packet Flow. Table 6-13 describes the fields. Figure 6-87 shows an example
QoS Policy Flow Form.
TABLE 6-13 Options for the QoS Policy Flow Form
Option Purpose
Target Device
Classes
The device classes to be included in this Flow.
Set Targets Brings up the Edit QOS Device Class List, allowing the user to select any combination of device
classes to include.Press and Hold the SHift key to select more than one device class.
Targets can also be added/removed by clicking the “Target” checkbox.
Device Class
table
Table of the Device Classes, Targets, and a description of the device class. Supported indicates there
are no detected errors.
Flow Name A pull-down of all existing flows.If selected, the parameters of the selected flow appear in the form.
Device Class A pull-down of the device classes that are included in this policy. This reflects the tic boxes chosen
in the Device Class table.
New Flow Brings up the Select New Name window. The user can choose to copy the parameters from the flow
currently displayed.
Copy Saves the parameters from the current Device Class target so they can be 'pasted' to another target
device class by the “translation” feature.
Paste Translates and applies the parameters that were “copied”. If there is no translation for a parameter it
will appear with square brackets around it, and be colored red. If there is similar parameter but the
value cannot be translated the value will be enclosed in square brackets and the entry will again be
colored red.
Flow Classifi-
ers
A table of the current classifiers. Delete removes the selected classifier. The Up and Down buttons
change the order of classifiers (and so the logical OR), but not the selection.
Classifier # The number of the classifier in the list. The order determines the precedence of the rules
Clear All
Classifiers
Delete all classifiers in the Flow Classifier table and return to the default classifier and value (ETH-
FORMAT=ANY).
New Classi-
fier
Adds a classifier to the Flow Classifier table with the default classifier and value (ETHFOR-
MAT=ANY). This classifier appears in the Classifier Parameter list and can be modified or replaced
Classifier
Parameters
A list of the parameters for the selected classifier. If more than one parameter is listed, the Up, Down,
and Delete buttons are active. The Up and Down buttons change the order of classifiers (and so the
logical AND), but the order does not affect the function
Parameter
pull-down
and value
field
A pull-down of the available parameters. As each one is selected, the associated value field appears.
Values may be selected from a list of values, where each element of the list can be a Name, an Ip or
MAC address, an integer range, a fixed point decimal range, or hexadecimal value. One parameter
TCPFLAGS is a list of named values selected with a drop-down menu.
For example, selecting VID will bring up a value field with 500, a default value. The user can then
overwrite this value of 500.

Add or
Replace
Parameter
If the parameter is not in the Flow Classifier table, it is added to the parameter list for that classifier
(and creating another AND condition). If the parameter has already been chosen, it replaces what is
already there with the new value.
The available Parameters and Values change as parameters are added, reflecting the interdependen-
cies between the parameters. For example if TCPDPORT is selected, PROTOCOL is added with a
value of IP and it range is restricted to only IP
Delete Flow Deletes the flow entry for all Target Device Classes. To remove the flow for a single Device Class
uncheck its “target” checkbox. When the flow is saved the entry for that Device Class will be
removed from the database.
