View Clusters and Nodes in the Topology

On the left navigation pane, click on and from Physical select Topology to see the clusters and nodes managed by GigaVUE-FM. The Gigamon nodes and other devices are represented by graphical icons. Connections between the nodes are represented by lines. Clusters appear as orange containers. Devices can be either discovered or manually added to the topology. The following figure shows an example star topology with three Gigamon clusters, Gigamon nodes, and other devices.

 

Figure 13

GigaVUE-FM Topology

The figure shows an example of leaf and spine topology.

There are two kinds of nodes displayed in the leaf and spine topology, as follows:

■

Leaf nodes, which are edge nodes and can also have TAPs or tools attached to them. All the leaf nodes are displayed within the Leaf container.

■

Spine nodes, which are the nodes to which the leaf nodes attach. All the spine nodes are displayed within the Spine container.

The leaf and spine configuration can be done only by using the CLI commands. For more information about multi-path leaf and spine architecture and configuration, refer to GigaVUE-OS CLI Reference Guide on the Gigamon Documentation Library .

The Topology page has the following menus and buttons:

Menu/Button	Description
Add	The Add menu has the following options: ■   Add Device(s)—opens an Add Device(s) page for selecting and manually adding nodes to the topology. For details, refer to Add Devices ■   Add Link(s)—opens an Add Link(s) page for adding links between nodes. For details, refer to Add Links ■   Add Tap—opens an Add Tap page for adding Gigamon TAPs to the topology. For details, refer to Add TAP.
Actions	The Actions menu has the following options: ■   Edit—opens the Edit page for a manually added node or link. The node or link must be selected for this option to be available. ■   Delete—deletes a manually added node or link. ■   Delete All—deletes all manually added nodes and links. ■   Reset Alignment—resets the alignment of clusters and nodes to the default alignment. ■   View Node Topology—shows the topology of a selected node. ■   Go to Node Overview—open the Overview page for the selected node.
Filter	The Filter button opens a Quick View for selecting filter criteria for the topology. The filter makes it possible to select only those items that you want to view in the topology, such as nodes of a certain type or specific models of Gigamon nodes.
Import	The Import menu supports the importing of custom nodes and links from an Excel spread sheet. For details, refer to Export and Import Topology.
Export	The Export menu supports the exporting of custom nodes and links to an Excel spread sheet. For details, refer to Export and Import Topology.
Topology View	The Topology View button switches the Topology view to the graphic representation of Gigamon nodes, links, and the various types of nodes. Topology is the default view.
Table View	The Table View button switches the view to a table that lists all the items in the topology. For details about Table View, refer to Table View.

The controls in the lower right-hand corner are used to move the topology up, down, left, right, and to zoom in or out. Clicking the center button makes a best fit of the topology on the page.

A context menu is available for clusters and nodes that includes options for realigning elements. Right-click on a cluster or a node to open the context menu, which stays open until you click elsewhere on the page. The options are as follows:

Menu Option	Description
View Node Topology	Opens the Node Topology page for the selected cluster or node. For more information about Node Topology, refer to Node Topology. You can also open the Node Topology by selecting Physical Nodes in the top Navigation pane, selecting the node or cluster, and then selecting Node Topology.
Go to Node Overview	Opens the Overview page for the selected node. You can also open the Overview page for the node by selecting Physical Nodes in the Navigation pane, and then selecting the node or cluster.
Align Neighbor	Aligns all the neighbors of the selected node or cluster. For details, refer to Align Neighbors.
Align Leaf Neighbor	Aligns only the immediate neighbors of the selected node or cluster. For details, refer to Align Leaf Neighbor.
Align Cluster	Aligns the nodes within a cluster container. For clusters with leaf and spine configuration, the leaf and spine nodes are aligned within their respective containers. For details, refer to Align Cluster.
Select Neighbor	Selects the cluster container or node and all of its immediate neighbors. The node or clusters and its neighbors can be moved as a unit. For details, refer to Select Neighbor.
