Holistic Topology View |
Topology now enables you to visualize all the fabrics in your network at once. You can double-click a node to view the interconnections of the nodes in the fabric using the LLDP and CDP protocol information. |

About Topology
About Topology
Topology helps visualize all the switches and endpoints known by Nexus Dashboard Insights and displays the interconnection of the nodes in the fabric using the LLDP and CDP protocol information. Topology also helps find the nodes that are impacted by anomalies.
Access Topology by navigating to Overview > Topology.
Views in topology focus on the node selected by the user. The default view is All Fabrics view. The different views are:
-
All Fabric View
-
Node Level View
All Fabric View
All Fabrics view displays the list of the fabrics managed by Nexus Dashboard Insights.
Click any specific node to view details available for it along with its connectivity to the other nodes. This is the Tooltip View. Tooltip displays the anomaly status, node name, node type, uplink connections and downlink connections. You can also click View More Details to view a page with detailed information about the node. To understand the details available, see Inventory.
Double-click to drill down and view the topology and all the switches connected to the node. The node level view has multiple levels and reveals the network connectivity details configured between different nodes. The node colors and the icon on the top right of the node represent the anomaly health for the node.
The nodes are interconnected by using lines. The line color shows connectivity health which is determined by operational status.
Breadcrumbs help you to navigate between views. The first element in the breadcrumbs is All Fabrics and the other elements are the names of the nodes that you double-clicked.
The actions dropdown allows you to toggle between vertical and horizontal layout for flexibility in display of the topology. Vertical Layout is the default layout. Click info icon on bottom right to get more information about the legend. It helps understand the node type, the node anomaly status, the node stack and the links used in the topology.
Use the zoom-in or zoom-out capability to change the scale of the viewed area in order to see more detail or less detail.
You can refine the displayed nodes by filters. Attributes available for filtering are relative to a specific view, and change according to the view selected. Use the following operators to filter the refinement:
| Operator | Description |
|---|---|
|
== |
With the initial filter type, this operator, and a subsequent value, returns an exact match. |
|
!= |
With the initial filter type, this operator, and a subsequent value, returns all that do not have the same value. |
|
contains |
With the initial filter type, this operator, and a subsequent value, returns all that contain the value. |
|
!contains |
With the initial filter type, this operator, and a subsequent value, returns all that do not contain the value. |
Filtering does not search for the attribute value across the nodes maintained in a given network topology, but only highlights the filtered node, if present in the current view of the topology.
Node Topology View
It displays a detailed view for a given switch and its connectivity to other nodes. In this view, you can click on the node to view details such as the endpoints configured, and connectivity information via tooltip. A maximum of 9 endpoints are displayed individually for any leaf node. To view others, double click the cluster-node. Click More to view the other endpoints not displayed individually.
