8-6 EXTREMEWARE ENTERPRISE MANAGER INSTALLATION AND USER GUIDE
USING THE POLICY SYSTEM
Figure 8-5: Basic Policy Definition
The ExtremeWare Enterprise Manager Policy System converts the high-level policy
definition you supply into a set of low-level QoS rules that it will implement on the
devices within the policy’s scope. To do this, the Policy system takes the following
steps:
1 Converts the endpoint components, application components, and traffic direction
components into traffic patterns.
2 Converts the policy treatment into QoS profiles.
3 Combines the traffic patterns and QoS profiles into QoS rules.
4 Uses the policy scope to determine to which device(s) the QoS rules should be
applied (see “Policy Scoping”).
5 Resolves any QoS rule conflicts using precedence relationships.
6 Configures the QoS rules on the network switches either automatically (if Auto
Configuration is on) or when you initiate the configuration using the Configuration
page.
