Layouts

The topology supports different layouts along with a Save Layout option that remembers how you positioned your topology.

  • Hierarchical and Hierarchical Left-Right - Provide an architectural view of your topology. Various switch roles can be defined that will draw the nodes on how you configure your CLOS topology.

    note.svg

    When running a large-scale setup, being able to easily view all your switches on a leaf-tier can become difficult. To mitigate this, Nexus Dashboard Fabric Controller splits your leaf-tier every 16 switches.


  • Circular and Tiered-Circular - Draw nodes in a circular or concentric circular pattern.

  • Random - Nodes are placed randomly on the window. Nexus Dashboard Fabric Controller tries to make a guess and intelligently place nodes that belong together in close proximity.

  • Custom saved layout - Nodes can be dragged around according to your preference. After you position as required, click Save to retain the positions. The next time you come to the topology, Nexus Dashboard Fabric Controller will draw the nodes based on your last saved layout positions.

Before a layout is chosen, Nexus Dashboard Fabric Controller checks if a custom layout is applied. If a custom layout is applied, Nexus Dashboard Fabric Controller uses it. If a custom layout is not applied, Nexus Dashboard Fabric Controller checks if switches exist at different tiers, and chooses the Hierarchical layout or the Hierarchical Left-Right layout. Force-directed layout is chosen if all the other layouts fail.

Status

The color coding of each node and link corresponds to its state. The operational colors and what they indicate are described in the following list:

  • Green - Indicates that the element is in good health and functioning as intended.

  • Blue - Indicates that the element is in a warning state and requires attention to prevent any further problems.

  • Yellow - Indicates that the element has minor issues.

  • Orange - Indicates that the element has major issues and requires attention to prevent any further problems.

  • Red - Indicates that the element is in critical state and requires immediate attention.
