Discovering Devices

 

You can discover and synchronize physical devices such as MX Series routers that function as service delivery gateways in your network that are managed by Edge Services Director.

Note

On MX Series routers, Edge Services Director connects to port 22 (the default port) on the Junos Space JA2500 Appliance or the Junos Space Virtual Appliance by using SSH. You can configure port 22 on the Junos Space appliances through Administration > Applications in the Junos Space Platform page. Select Network Application Platform and click Actions > Modify Application Settings. Change SSH port for device connection field to 22.

Device discovery is a three-step process in which you specify the target devices, the discovery options, and the schedule options.

While in Build mode, from the Tasks pane, select Service Gateways. The Service Gateways page is displayed. Click Discover Devices to create a discovery profile or a job, and to view the previously created discovery profiles

Preparing MX Series Devices for Discovery

Juniper Networks MX Series 3D Universal Edge Routers—MX240, MX480, and MX960—include all standard Ethernet capabilities as well as enhanced mechanisms for service providers to provision and support large numbers of Ethernet services in addition to all Layer 3 services. You can discover these routers and manage them as switching devices from Edge Services Director. However, before discovering these MX devices from Edge Services Director, you must ensure that the Junos OS running on the device is at the required level and that the network service mode is set to LAN.

To prepare an MX Series device for discovery:

  1. Log in to the MX Series device by using the CLI.
  2. Ensure that the device is running a version of Junos OS that is compatible with Edge Services Director. Use the operational mode command show version to determine the Junos OS software release.
  3. Commit your changes.

    The MX Series device is now discoverable from Edge Services Director.

Specifying a Discovery Profile and the Target Devices

You can add devices to Edge Services Director for device discovery by using the Add icon on the Service Gateways page. A discovery profile is created, which is a discovery job that contains the list of devices and its properties to be retrieved and added to the Edge Services Director database.

Note

If you want to discover and manage MX Series devices—MX240, MX480, and MX960—from Edge Services Director, you must first make these devices discoverable. For more details see Preparing MX Series Devices for Discovery.

To specify a discovery profile and the target devices that you want Edge Services Director to discover:

  1. From the View selector, select Gateway View. The workspaces that are applicable to this view are displayed.

  3. From the View selector, select Gateway View or Device View. The workspaces that are available in this view are displayed. The Gateway view displays the service delivery gateway (SDG) groups and the SDGs that are part of the high availability pair in an SDG group. The Device view displays the SDGs based on the device type, and within the device type, the devices are organized by the device model. For example, all models of MX960 routers are grouped together under one node in the tree
  4. From the Junos Space user interface, click the Build icon on the Edge Services Director banner.

    The functionalities that you can configure in this mode are displayed in the task pane.
