About Topology
About Topology
Topology displays the interconnection of the nodes in the fabric using the LLDP and CDP protocol information. The topology view helps find the nodes that are impacted by anomalies.
Topology displays all the nodes and the anomaly levels for the selected sites with a radial graph.
The page displays the list of nodes, node types, LLDP information from a leaf node to another leaf node, IPN, and anomaly level on the link. In this view, you can distinguish between a spine node, leaf node, and border leaf node by the different avatars.
IPN links are spine node links connected to the IPN and are distinguished from the links connected to the internal leaf nodes. The IPN is shown as a physical entity in the topology.
Access Topology by navigating to Overview > Topology.
Toggle Spine nodes, Leaf nodes, and Controllers to add or remove objects from the topology view. Toggle each anomaly score to add or remove from the topology view.
The various anomaly scores available are:
-
Warning
-
Major
-
Critical
Use the zoom in capability to narrow down on portions of the infrastructure based on logical constructs such as EPG, VRF, Tenant. View, sort, and filter anomalies through the topology work pane.
You can refine the displayed nodes by the following filters:
-
Name - Display only nodes with a specific name.
-
VRF - Display only nodes from a specific VRF.
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. |
The anomaly score is represented by the color of the node in the topology.
The different colors show the anomaly level for that object, where:
-
Orange indicates that this object is in an Anomaly Level Major state
-
Red indicates that this object is in an Anomaly Level Critical state
-
Gray indicates that the Anomaly Level for this object is unknown
Hover over the node to view an overview of the following details:
-
Type of node
-
Name of the node
-
Anomaly level
-
Number of nodes it is connected to
Click the node on the topology to view additional details for the node. To understand the details available, see Inventory. Click 'Actions' to view inventory details.
Topology Limitations
Nodes that do not have LLDP information are not shown in the topology.
Cisco Nexus Dashboard Insights Topology
Nexus Dashboard Insights on NDFC supports the following topologies:
VxLAN : Leaf-Spine topology for 3-HOP Flow Telemetry
The Flow Telemetry line crossing every switch in the illustration represents the switches that are capable of exporting the Flow Telemetry data. For Example: With two flow telemetry HOP lines, the packet flows from Leaf 1.1 to Spine 1.1 and then to Leaf 1.3. This is considered as 3-Hop Flow Telemetry.
Supported Scenarios
The Nexus Dashboard Insights topology supports the following scenarios.
VXLAN
-
vPC on leaf switch
-
Border spine switch
-
Border leaf switch
-
IR or Multicast underlay
-
EBGP or IBGP
-
IPv4 underlay
-
IPv4/IPv6 overlay
Legacy/Classic LAN
-
vPC on leaf switch
-
IPv4 or IPv6
Supported Roles
The Nexus Dashboard Insights topology supports the following roles.
