Configuring Policies

This chapter describes policy configuration, including:

Policy Overview

Policy configuration defines the binding of a topology (VLAN), ingress and egress rate profiles

applied to the traffic of a station, and filter rules.

Policies don't need to be fully specified; Unspecified attributes are retained by the user or

inherited from Global Policy definitions (see “Configuring the Global Default Policy” on page 7-16

for more information).

Default Global Policy definitions provide a placeholder for completion of incomplete policies for

initial default assignment. If a policy is defined as Default for a particular VNS, the policy inherits

incomplete attributes from Default Global Policy definitions

Configuring VLAN and Class of Service for a Policy

From the VLAN & Class of Service tab you can assign a previously configured topology to a

policy. You can also launch the Topology Configuration page to edit an existing topology or create

a new one. For information about how to configure a topology, refer to Chapter 4, Configuring

Topologies.

In general, Class of Service (CoS) refers to a set of attributes that define the importance of a frame

while it is forwarded through the network relative to other packets, and to the maximum

throughput per time unit that a station or port assigned to the policy is permitted. The CoS defines

actions to be taken when rate limits are exceeded.

To configure VLAN and Class of Service for a policy:

1. From the top menu, click VNS Configuration.

The Virtual Network Configuration screen displays.

2. In the left pane expand the Policies pane and click the policy you want to edit, or click the

New button to create a new policy.

The Policy configuration page displays. By default, the VLAN & Class of Service tab displays

(Figure 5-1). Table 5-1 describes the fields and buttons on the VLAN & Class of Service tab.
