The system uses the local network objecta logical definition created and stored in the Exinda lilbrary, can represent any network component to determine the location of all other network objects. The location of network objects is used to determine whether hosts and users are internal or external to the LANLocal area network behind your Network Orchestrator appliance. In the Configured Appliances area, select Local Network Objects in the menu. Click the appliance where you want to configure the local network object. For more information refer to Configuring local network objects in the EMC.

Network objects are used for identifying the traffic affected by the policy as well as for monitoring traffic. Consider the following:

• If you want to use a network object in the creation of a virtual circuitlogical definitions that partition a a physical network circuit and used to determine what traffic passes through it and how much or policy, create a network object in the librarythe Exinda repository for network objects and their definitions. If you imported your network objects from your appliance, you may not need to create any network objects.
• If you want to send a network object to the appliance for monitoring purposes (not for policy creation), then create a network object in the configured appliance group, which also adds the network object to the library. Or create a network object in the library then add it to the configured appliances group.
• If you use a network object in the definition of a virtual circuit or policy for a given appliance group, then the network object is automatically added to the appliance group configuration. For more information refer to Creating network objects in the EMC.

Custom applications can be used for both identifying traffic affected by the policy, and for monitoring traffic. Consider the following:

• If you want to use a custom application in the creation of your virtual circuit or policy, create a custom application in the library. When you create or edit the Virtual Circuits or policies, your custom application becomes available for selection.
• If you want to send a custom application to the appliance for monitoring purposes, you need to add the application to a monitored application group.
• If you use a custom application in the definition of a virtual circuit or policy for a given appliance group, then the custom application is automatically added to the appliance group configuration. For more information refer to Configuring applications with the EMC.

Schedules can be used to specify when policies or virtual circuits takes effect. If you want to use a schedule in the creation of your virtual circuit or policy, first create a schedule in the library. When you create or edit the virtual circuits or policies, your schedule can then be selected and automatically added to the appliance group configuration. For more information refer to Configuring schedules in the EMC.

Each object element of the Policy Tree is stored in the library for use by other appliance groups or other areas within the Optimizer Policy Trees. For more information refer to Optimizer Policy Tree.

The circuit type specifies the intended use of a circuit, for example, "Internet", "Voice", or "MPLS". Circuits and appliance bridges are mapped to these circuit types. The circuit is sent to the appliances that have bridges mapped to the same circuit type as the circuit. Go to the library and create your required circuit types. For more information refer to Circuit types in the EMC.

This determines the bridges to which the circuits are mapped on the appliances. Go to the configured appliances. Click Bridges/Circuit Type Mapping, and for each appliance specify the Circuit Type for each bridge. For more information refer to Working with bridge/circuit type mapping.

Circuits specify the physical connections to the WANWide Area Network or Internet. Create a circuit in the Optimizer Policy tree for the configured appliance group. Or create a circuit in the library and add it to the Optimizer Policy tree for the configured appliance group. For more information refer to Circuits.

Virtual circuits define what traffic is processed in a partition and how much bandwidth it is allowed. Create a virtual circuit in the Optimizer Policy tree for the configured appliance group. Or create a virtual circuit in the library and add it to the Optimizer Policy tree for the configured appliance group. For more information refer to Virtual Circuits.

Policy sets are groups of policies that will be added to the Virtual Circuits. There are pre-created policy sets in the library that correspond to the sets that result from running the wizard on the appliance.

Add a policy set to a configured appliance group Optimizer Policy tree virtual circuit. You can also create policy sets from the Optimizer Policy tree or in the library. For more information refer to Creating policy sets in the EMC.

Policies are the rules that control the traffic. When adding or editing a policy set, you can add or edit a policy. For more information refer to Policies.

Changes are sent to the appliances within an Appliance Group only when you choose to send the configuration. For more information refer to Sending configuration changes to the appliances.
