Viewing The Shortest Path Between Two Nodes; Follow Flow - HP HPE VAN SDN Controller 2.7 Administrator's Manual

Collapse All
Collapse the topology display to show only the number of end nodes connected to each switch,
instead of showing all end nodes (the default) which can present a cluttered display where a
large number of end nodes are connected to the OpenFlow switches. To collapse or expand
end-nodes for a particular switch, double-click the selected switch.
To collapse all end nodes, select View→Collapse All.
Auto Refresh
To automatically refresh the topology, select View→Auto Refresh.
Reload
To reload the whole topology, click the Reload button in the top right of the topology view. When
the topology is reloaded, Highlight, collapse, Collapse All, selection, and node labels will be reset.

Viewing the shortest path between two nodes

You can view the shortest path between two nodes as follows:
1. Select the source node and click Src or press S.
2. Select the destination node and click Dst or press D.
The controller displays the path between the two nodes as a line, see
Features like Collapse all, collapse a single node and highlight a particular node using Ctrl click
are not allowed when a path is selected.
