Create a Partition
|
|
Note: To perform this task from PolicyCenter, you must first select a configuration from the Editing Configuration
drop-down list at the top of the page.

To create a partition:
1. Click the manage tab.
2. In the left window pane, select the class for which
you want to create a partition.
3. In the right window pane, click partition
and select add. The New Partition window displays.  show screen
4. Define the partition using the following parameters:
| Field |
Description |
| Size |
The minimum partition size, expressed in bits per second (bps)
or as a percentage (%) of the parent partition's size. If
the size is entered in bits per second, you can follow the integer
by a “k” (thousands), “M” (millions), or “G”
(billions). The minimum partition size is 1000 bps (1024 bps on
PacketShaper 3500, 7500, 9500, and 10000 models). See Sizing
a Static Partition for additional details and examples.
Note: A guaranteed rate must be available within the minimum
partition size. For the purpose of calculating whether there is
enough bandwidth available in a partition to satisfy a guaranteed
flow, it is assumed that all guaranteed rates are being used. For
example, if the partition minimum size is 50k and the class has
a policy with a guaranteed rate of 20k, a maximum of two flows can
exist, even if the two flows are only using 15k.

| Burstable |
When selected, allows the partition to use available excess bandwidth
if needed. When this box is unchecked, the partition has a fixed
size; when it is not using its reserved bandwidth, that bandwidth
is available to other traffic.
Note: A burstable partition simply allows larger
flows, not more flows.
|
| Limit |
A maximum bandwidth limit to be used when the partition bursts.
This limit must be greater than the partition minimum. The limit can
be specified in bits per second or as a percentage of the parent partition's
size. |
5. Click add partition to create the partition.
If you specified the partition size as a percentage, PacketWise will calculate
the absolute size in bits per second and display the results in the Traffic
Class window.
6. If you want to make this partition dynamic, click
details and then refer to Create
a Dynamic Partition.
Notes:
- In order for partitions to take effect, traffic shaping must be enabled.
See Enable/Disable Traffic Shaping.
- When creating partitions, make sure you don’t allocate bandwidth
in such a way that Inbound/Default and Outbound/Default get “starved”
— that is, there is no bandwidth available for these classes. If
this happens, traffic classification and policies may not work as expected.
