Sorting and Filtering Options in the Network Information Table

This topic describes the sorting and filtering options that are available in the network information table at the bottom of the topology view.

Sorting from Column Headings

You have the option to sort the display of network elements in the network information table by any column heading. Click in the column heading to sort ascending and click again to sort descending. The up or down arrow in the column heading tells you which sort order is displayed. Figure 1 shows an example of the arrow.

Note:

You only see the up or down arrow when you click in the column heading.

Filtering from Table Rows

Right-click on a table row under any of the table tabs (Nodes, Links, Tunnels, Interfaces) to see the filtering options that are available from that network element. For example, if you right-click a node in the Nodes tab of the table, you have the options shown in Figure 2.

Figure 2: Right-Click Filtering Options ExampleRight-Click Filtering Options Example

Table 1, Table 2, and Table 3 describe the options available when right-clicking an element in the Nodes, Links, and Interfaces tabs. Right-clicking a tunnel in the Tunnels tab or a demand in the Demands tab launches the Show Path tool, which is addressed in a later section.

Note:

To clear a filter so that all network elements are again displayed, click Clear Filter in the lower right corner of the network information table (only visible when a filter is in effect).

Option

Function

Links at Node

Switches the display to the Links tab and shows only those links that have the selected node as Node A or Node Z.

Interfaces at Node

Switches the display to the Interfaces tab and shows only those interfaces with the selected node.

Tunnels on/through Node

Switches the display to the Tunnels tab and shows only those tunnels that start, end, or run through the selected node.

Tunnels starting at Node

Switches the display to the Tunnels tab and shows only those tunnels that start at the selected node.

Tunnels ending at Node

Switches the display to the Tunnels tab and shows only those tunnels that end at the selected node.

Tunnels passing through Node

Switches the display to the Tunnels tab and shows only those tunnels that pass through the selected node.

Function

Nodes on Link

Switches the display to the Nodes tab and shows only those nodes that are on the selected link.

Interfaces on Link

Switches the display to the Interfaces tab and shows only those interfaces that are on the selected link.

Tunnels on/through Link

Switches the display to the Tunnels tab and shows only those tunnels that run on or through the selected link.

Function

Link at Interface

Switches the display to the Links tab and shows only those links that have the selected interface.

Filtering Using the Search Function

The search icon (magnifying glass) in the bottom tool bar of the network information table behaves differently depending on which tab (Nodes, Links, and so on) you are in. For the Nodes and Links tabs, clicking the search icon brings up a simple text box beside the icon as shown in Figure 3.

Figure 3: Text Search BoxText Search Box

The rows are filtered to display only those elements satisfying the search criteria. This does not change the topology map. To clear the filter so that all network elements are again displayed, click the X beside the search box.

In the Tunnels, Demands, and Interfaces tabs, clicking the search icon brings up a filter window in which you can enter or select specific search criteria appropriate to that network element type. For example, see the Tunnel Filter window shown in Figure 4.

Once you have entered/selected the search criteria, click OK. The filter window closes and the table displays only the rows that satisfy the search criteria. To clear the filter so that all network elements are again displayed, click Clear Filter at the far right of the bottom tool bar.

Using the Show Path Tool from the Tunnels or Demands Tab

To launch the Show Path tool, right-click a network element in the Tunnels or Demands tab of the network information table, and select Show Path. The Paths window opens to the right of the topology map, displaying the current route for the selected tunnel, hop by hop. An example is shown in Figure 5.

Figure 5: Paths WindowPaths Window

Note that the path is highlighted in the topology map. You can click Highlight Path if the path is not already highlighted, which it might not be if you clicked to a different network information table tab and then clicked back.

Currently, only the current route can be displayed. A future release will support secondary route display from the Paths drop-down menu to the right of the Current Route heading.

At the bottom of the display is an option to Hide Unrelated Nodes on the topology map. Click the check box to select or deselect this option.
