Circuits
Circuits define physical connections to the WANWide Area Network or the Internet. A circuit defines the inbound and outbound bandwidth and the named circuit type.
On an Exinda Appliance, a circuit specifies the named bridge (or bridges) to which it is bound. In the Exinda Management Center, the binding to bridges is through a designated Circuit Type. Circuit Types represent the intended use of a circuit. So you can configure a circuit for multiple appliances without requiring the bridges on the appliances to have the same name. This is favorable where the number of bridges or names of bridges or the cabling of the bridges is not consistent across the appliances.
If multiple bridges on an appliance are mapped to the same Circuit Type, then all those bridges will be bound to the single circuit in the Policy Tree that is configured with that Circuit Type. To learn how Circuit Types are used to determine which circuits are sent to the appliances, read Circuit Types.
Circuits can be created in the Configuration Library directly and then later assigned to an Optimizer Policy Tree, Circuits can also be created in an Optimizer Policy Tree, from where the configuration is saved to the Configuration Library so that it can be used elsewhere. The circuits within a tenant must have unique names. When a circuit is modified, all uses of it are modified.
Circuits are part of the Optimizer Policy Tree. To learn how circuits, Virtual Circuits, policy sets, and policy rules work together, see Policy Tree.
Where do I find circuits?
Circuit librarythe Exinda repository for network objects and their definitions items can be found in Library > Circuits. Also, the circuits that are applied to appliances can also be found in the policy trees for each appliance group. Go to the (desired appliance group) > Optimizer Policy Tree.
To create a circuit in the Configuration Library
- Go to Library > Circuits.
- Click Create new circuit in the library ...
- In the Name section, key-in the name of the circuit. The name must be unique in the tenant.
- In the Bandwidth section, key-in the Inbound Bandwidth and the Outbound Bandwidth. The bandwidths can be specified in kbps, Mbps, or Gbps.
- In the Bind to Circuit Type section, select the Circuit Type.
NOTE
The circuit type represents the purpose of the circuit; it is a user created object. If the desired circuit type does not exist, you can click Create new circuit type in the library to create it. For more information refer to Circuit types in the EMC.
- Click Create . The circuit appears in the library list.
To create a new circuit directly in the Policy Tree
- Go to the (desired appliance group) > Optimizer Policy Tree.
- Click Create new circuit.
- In the Name section, key-in the name of the circuit. The name must be unique in the tenant.
- In the Bandwidth section, key-in the Inbound Bandwidth and the Outbound Bandwidth. The bandwidths can be specified in kbps, Mbps, or Gbps.
- In the Bind to Circuit Type section, select the Circuit Type.
NOTE
The circuit type represents the purpose of the circuit; it is a user created object. If the desired circuit type does not exist, you can click Create new circuit type in the library to create it. For more information refer to Circuit types in the EMC.
- Click Save. The circuit is added to the Policy Tree and is also saved to the configuration library.
To add a circuit to a Policy Tree
- Go to the (desired appliance group) > Optimizer Policy Tree.
- Click Add circuit from library.
- Select the desired circuit from the drop-down list.
