## Discovering SD-WAN devices in OpManager

To add and monitor an SD-WAN device in OpManager, follow these steps:

- Navigate to **Settings** > **Discovery** > **Add SD-WAN**.
- Select the **SD-WAN device model** from the list.
- Provide the **SD-WAN IP address** or **hostname**.
- Select the **SD-WAN credentials** from the drop-down menu or click **Add Credentials**.
- (Optional) Under **Advanced Settings**, configure authentication details for **child devices**.
- Click **Discover** to initiate the SD-WAN discovery process.
- Once discovery is complete, the **controller, sites,** and **edge devices** will be added to OpManager’s inventory.

## SD-WAN snapshot page

Once the SD-WAN devices are discovered, they will be added to the inventory. Follow these steps to access their details:

- Navigate to **Inventory** or **Network** in OpManager.
- Locate and click on the **SD-WAN device** to open its **snapshot page**.

![SD_WAN](https://www.manageengine.com/network-monitoring/help/images/sd-wan-2.PNG)

The snapshot page provides:

- **Status & Availability** – Displays the current state of the SD-WAN device.
- **SD-WAN Summary** – Offers an overview of key performance metrics.
- **Basic Device Details** – Includes model, serial number, and IP address.

## SD-WAN topology map

The **Topology Map** provides an interactive view of SD-WAN components, including controllers, sites, and edge devices. To access the topology map:

- Open the **SD-WAN snapshot page**.
- Click on the **"Topology Map" tab**.
- The topology map displays:
  - **Controllers** – Centralized components (vManage, vSmart, and vBond) that manage and control SD-WAN operations.
  - **Sites** – Individual network locations managed under vManage.
  - **Edge Devices** – Hardware or virtual appliances deployed at sites.

## Managing SD-WAN sites

A **site** represents a physical or logical location within an **SD-WAN network**, such as branch offices or data centers, where SD-WAN devices are deployed.

### Managing and monitoring sites

To efficiently manage and monitor sites, users can take the following bulk actions using the **Actions** button at the top-right corner:

- **Manage** or **unmanage** sites.
- **Suppress** or **unsuppress** alarms.

### Viewing site details

- Open the **"Sites" tab** on the SD-WAN snapshot page.
- The **Sites** section displays the following details:
  - **Site Name** – The designated name of the SD-WAN site.
  - **Site Health** – Reflects the overall operational condition of the site.
  - **Device Health** – Shows the status of all devices associated with the site.
  - **Tunnel Health** – Displays the performance status of network tunnels.
  - **Actions** – Provides options to view device-specific performance graphs.

## SD-WAN devices

You can find details about SD-WAN devices, including controllers and edge devices in the Devices tab. To access SD-WAN device details:

- Open the **"Devices" tab** from the SD-WAN snapshot page.
- The following key metrics common for Controllers and Edge Devices are displayed:
  - **Host Name** – The name of the SD-WAN controller or edge device.
  - **IP Address** – The unique network address assigned to the device.
  - **Health Status** – Indicates whether the device is functioning normally or experiencing issues.
  - **Device State** – Displays the current operational status (e.g., Active, Inactive, Down).
  - **Device Model** – Specifies the hardware or software version of the SD-WAN device.
  - **Serial Number** – A unique identifier assigned by the manufacturer.
- In addition to the above, the Edge devices section also contain:
  - **Site Name** – Identifies the SD-WAN site to which the edge device belongs.
  - **Global State** – Represents the overall status of the device within the SD-WAN network.

## Managing SD-WAN tunnels

Tunnels are secure, virtual communication links between SD-WAN devices that ensure efficient data transmission by optimizing traffic flow across multiple network paths.

### Manage tunnels

To manage tunnel performance, users can perform bulk actions via the **Actions** button in the top-right.

- **Set performance thresholds** and alert rules.
- **Manage or unmanage** tunnel endpoints in bulk.
- **Suppress or unsuppress** alarms in bulk.
- **Edit thresholds** and view tunnel-specific performance graphs.

### To view tunnel performance:

- Open the **"Tunnels" tab** from the SD-WAN snapshot page.
- The **Tunnels** section provides key metrics, including:
  - **Tunnel Endpoints** – Specifies the source and destination endpoints of the SD-WAN tunnel.
  - **Health Status** – Reflects the operational state of the tunnel.
  - **State** – Displays the current activity level (e.g., Active, Inactive, Degraded).
  - **Quality of Experience (QoE)** – Measures overall performance based on network conditions.
  - **Latency (ms)** – The time delay (in milliseconds) for data to travel across the tunnel.
  - **Packet Loss (%)** – The percentage of data packets lost during transmission.
  - **Jitter (ms)** – The variation in latency affecting data consistency.
  - **Local IP** – The IP address of the tunnel’s local endpoint.
  - **Remote IP** – The IP address of the tunnel’s remote endpoint.

## Decommissioning SD-WAN devices

If an SD-WAN device reaches **End of Life (EOL)** or is no longer in use:

- The device can be **marked as unmanaged** in OpManager.
- A **decommissioning alert** will notify administrators of the status change.

## ReDiscovering SD-WAN

Rediscovery is performed when there are significant changes to a device, such as hardware modifications, interface updates, or adjustments to its associated configuration. To rediscover SD-WAN:

- Go to the snapshot page, and click on the menu icon on the top right.
- Click on **ReDiscover device**.
- Select an existing credential, or add a new one and click **ReDiscover Now**.
- The SD-WAN device will be rediscovered and added into OpManager.

## Generating advanced reports

OpManager’s **Advanced Reports** enable users to create customized reports by selecting specific performance monitors, applying criteria, and grouping data. To create an Advanced Report for SD-WAN:

- Go to **Reports** > **OpManager** > **Advanced Reports**.
- Click on the **"Create New Report"** button in the top-right corner. Select **SD-WAN** in the module type. [Click here](https://www.manageengine.com/network-monitoring/help/advanced-report.html) for detailed steps on creating an advanced report in OpManager.
