Dependencies

When one device depends on another, a line connects the parent and child devices in Panorama, with the corkscrew end of the line leading to the child.

Why Dependencies

Dependencies are created to suppress alerts in child devices when their parent device encounters an alert condition. For example, routers and switches are often identified as the parent devices of the other devices on their network. If power goes out for the router or switch, alerts for the dependent child devices are suppressed to avoid redundant alerts for the same issue.

How Dependencies are Created

Dependencies are created in two ways:

• When a discovery scan automatically detects a dependency between devices. Credentials to access the parent device are required for a discovery scan to build these dependencies automatically.
• Manually. You can create or edit device dependencies within Panorama. You can also Update Device Dependency manually from the Devices menu.

Editing Device Dependencies in Panorama

Click the Edit Device Dependencies icon in Panorama to manually change dependencies in a topology. Click the save icon when you done making any changes.

• Deleting Dependencies - While in edit mode, click the icon of a dependency link.

  

• Adding Dependencies - While in edit mode, click and drag a new dependency link from the parent device to the child device.

  

Expanding or Collapsing Parent/Child Hierarchies

Once devices are linked by dependencies, you can expand or collapse a hierarchy by clicking the or icon next to a parent node.
