SDN Logical Topology

Edit online

The SDN Logical Topology widget displays Cisco ACI overcloud objects and their interconnections. For example, Tenants, Application Profiles, Endpoints, Endpoint Groups, PODs, etc.

Note: Physical ACI Network topology (leaf & spine switches and their connections, also APICs and VMs) can be viewed via SevOne Data Insight 3.x Topology widget. Y ou may add both SDN Logical Topology widget and SevOne Data Insight 3.x Topology widget to the same Data Insight report tab in order to see both ACI physical and logical topologies on the same report.

Linking

Edit online

The Linking tab enables you to select a data element and link it to a related report or report template. Perform the following steps to add, delete, and edit links.

Note: Linking for the SDN Logical Topology widget works with the Table and Tree visualization. However, for Tree visualization, only report templates linked to Device A and Object A are applicable. Enabling linking for Device Z and Object Z applies to Table visualization only and has no effect on the Tree visualization.

SDN Logical Topology Linking

Perform the following steps to set the widget settings for Linking tab.

  1. Include report links allows you to include the report links that you configure. Enable to include the report link that you configure. If you want to prevent the report link from being included, disable it. Continue with the steps below to configure report link(s).
  2. Switches for individual report links are selected by default. If you wish to exclude a specific report link, disable the switch for it.
  3. Use the Clicking on drop-down to select a data item that you want to link with the report or report template. When you select a data item for a report link, that data item is no longer listed as an option for other report links as it has already been used. You can apply multiple reports/report templates to the selected data item.
  4. Click the Links to report drop-down and select one or more reports or report templates to display when you click on the data item that you specified in the previous step.
  5. To remove a report link, click Delete icon.
  6. If the report link has been deleted, you may click Add report link button to add.

    1. Enable Hide rows with missing data to hide rows with no data. SDN Logical Topology Charts Table

Tree

Edit online

The Tree visualization displays data in a tree format. The focal device is the root of the tree and branches out to display objects on the first level. Each first-level object further branches out to display any objects connected to it. To collapse or expand branches, click on the node and select option Toggle Children (to toggle to node's immediate children) or Toggle Subtree (to toggle to the node's entire subtree). The root node is named after the focal device, while the other nodes are named after the objects they represent. Hover over a node to display details about it. Perform the following steps to set the widget settings for the Tree visualization.

  1. Select the Tree visualization by clicking Tree visualization.
  2. TREE
    1. Click the Orientation drop-down and select Vertical for a vertically oriented tree or Horizontal for a horizontally oriented tree.
    2. Click the Path Type drop-down and select Straight, Diagonal, or Curve to specify the type of path to display between nodes.
    3. For Initial Depth, enter a number from 1 to 10 to specify how many levels are expanded initially.
    4. For Maximum Depth, enter a number from 1 to 10 to specify the maximum levels you can expand.
    5. For Space between branches, enter a number from 1 to 10 to specify the amount of space between branches.
    6. For Space between nodes in a branch, enter a number from 1 to 10 to specify the amount of space between the nodes of each branch.
    7. Select the Enable "Display All" in First Level Filter check box to provide "Display All" option from First Level Filter in report generated.
  3. NODES
    1. For Node Size, enter a number to specify the size of the nodes.
    2. Select the Enable Collapsing check box to enable collapsing of tree branches.
    3. Select the Abbreviate Names check box to abbreviate the names of nodes. In the Name Length field, enter the maximum number of characters that the names can have.

  7. Click the Refresh Tree button to apply the actions taken in the report generated.SDN Logical Topology Charts Tree 1SDN Logical Topology Charts Tree 2
Note: In some cases, the Tree view will omit nodes. For example, link loops cannot be visualized as a tree, so any connections back to parent nodes will not be displayed. However, you can view them using the Table visualization.
Important: You have the ability to link between the SDN Logical Topology widget and SDN Fault Messages widget by using the Report Linking functionality available from the SDN Logical Topology widget.
