When looking at the Exinda Optimizer, the Circuit Level is the highest possible level in the hierarchy, meant to represent your physical pipe.
This article provides general information and how to upgrade or downgrade the circuit size of Exinda.
- The Circuit in the Optimizer of the Exinda represents a physical connection. While it can be further subdivided into Virtual Circuits and Policies, the Circuit Level itself is the highest possible level.
- Any connection coming into the Exinda; whether it spans one bridge or multiple bridges should be considered a circuit. For example, if a topology has multiple physical connections coming in, such as a standard internet link and an MPLS (Multiprotocol Label Switching) link, each one should be its circuit in the Exinda.
- The bandwidth assigned to a circuit should be reflective of the bandwidth of the physical connection going into the device. The Exinda uses the circuit size as a determination at maximum speed to shape traffic to a basic level. From there, it subdivides into the effective bandwidths for Virtual Circuits and the policies.
- For example, if a circuit bandwidth is set to 10Mbps, all traffic going through the Exinda - whether it is shaped by a Virtual Circuit or policy or neither - will only get a maximum of 10Mbps, regardless of how big the physical connection is. If an ISP is providing a bandwidth of 200Mbps, the circuit size for that link should be 200Mbps; otherwise, bandwidth will be missing and performance will not be as expected for the device.
- If the main network link is upgraded e.g., from 20M to 40M then along with increasing the circuit size, make sure that Exinda license is also upgraded from 20M to 40M else it will show optimizer error.
- Verify if the license can support the amount of traffic before upgrading or downgrading the main circuit size of Exinda. It is shown in Dashboard > System tab > Licensed Model field.
- Once verified, upgrade or downgrade by navigating to Configuration > Optimizer > Edit Main Circuit
- Then change the value of Inbound Bandwidth and Outbound Bandwidth according to its need.
- Apply the changes and restart the Optimizer.
