Figure 108. IPX QoS Precedence dialog box
6. Assign one of the precedence values shown in the Order list to each of the IP-flow
fields shown in the Flow Components list. To assign a precedence value to a field,
select that field and then click the Up and Down buttons until the field is listed next to
the desired precedence value.
You may assign precedence values from 1 to 7, where 1 is the highest precedence value.
The default precedence values of the fields are Destination Network Address (1),
Source Network Address (2), Destination Node Address (3), Source Node Address (4),
Destination Socket Address (5), Source Socket Address (6), IPX Interface (7).
7. Click OK .
Creating QoS Profiles
On the SSR, you can have multiple IP, IPX, and Layer-2 flows. You create a QoS profile for
each of the flows you want to define on the SSR. When creating a QoS profile in
Configuration Expert, you do so by performing the following tasks:
• Specifying the name of the flow.
• Setting a priority for flows based on the fields of the flow. Setting priorities helps
ensure that critical traffic will reach its destination even if the exit ports for the traffic
are experiencing greater than maximum utilization.
• Setting the values of packet fields. The SSR will use these values as blueprints or
templates for the packets relevant to the flow type (IP, IPX, or Layer-2).
