Left Pane Network Elements in the Topology Map Window


Navigate to Network Elements > Nodes to display groups and nodes in a tree view in the topology map window left pane as shown in Figure 1.

All groups defined in the network are displayed with group elements indented underneath. To expand or collapse a group, click the +/- icon to the left of it. Selecting a node or collapsed group in the list highlights it on the map display.

You can add an element to a group by selecting the element name, dragging it, and dropping it over the group name. Right-click a group or node for additional options.

Navigate to Network Elements > Links to display all links associated with the protocol selected in the left pane Protocols subview. For example, if you select MPLS-TE in Protocols, then the Links list displays only the links associated with MPLS-TE. The link names are displayed in a list view in the left pane as shown in Figure 2.

Selecting a link name in the list highlights it in the topology map window. Clicking the links on the topology map also highlights them on the Links list.

Select Network Elements > Facilities to display a list of facilities as shown in Figure 3.

A facility is a group of links or nodes that are likely to fail together. It is used in failure simulations where accurate modeling requires the simultaneous failure of specific links or nodes. For instance, if several links travel over the same fiber, a fiber cut breaks all of them at once. In this case, you can define a facility to represent the Shared Risk Link Group (SRLG) containing those links. Another example is the set of switches on one floor of a large data center, together with all the links going into or out of that floor.
