User Interface
Starting WAE Design
To start WAE Design from the directory in which the WAE Design software is installed, do one of the following:
- On Windows or Linux, double-click the wae_design executable.
- On a Mac, navigate to the directory where you unpacked the distribution and double-click the WAE_Design application. Alternately, from the Terminal, enter:
(Optional) On Windows, you can associate the plan file using the.pln format with the wae_design executable. Double-clicking a.pln file opens the plan in a new instance of the GUI.
Main Window
The WAE Design GUI is divided into the following primary sections. Figure 2-1 shows the GUI with a sample us_wan.txt
plan in the network plot area.
- Menus—Menu selections for network modeling, simulation, and optimization.
- Visualization toolbar—Drop-down lists and icons that control how the network is displayed.
- Plan file tabs—Identify which plan is currently opened. There can be multiple plans open; the tab with a white background is the active plan. To bring a plan to the forefront and make it the active plan, click its associated tab.
- Network plot—Displays a visual representation of the network topology. The color on each interface represents the percentage of traffic utilization on that interface. Rows that are selected in the tables, such as demands or interfaces, are highlighted in the plot with additional graphical attributes.
- Tables—Display network properties, including both measured and simulated information, for the network plan.
- Status bar—Identifies the network simulation mode.
- Context menus—Let you right-click anywhere to view a list of actions that you can take.
Figure 2-1 WAE Design User Interface
Visualization Toolbar
The Visualization toolbar (Figure 2-2) provides a convenient way to change the visual aspects of the network plot.
Figure 2-2 Visualization Toolbar
- L3/L1 View—A toggle button to change the view between Layer 3 (L3) and Layer 1 (L1). You can also simultaneously view L3 and L1 networks. This is set in the Layer 1 tab of the Plot Options. For more information, see Layer 1 Simulation .
- Network Plot—A drop-down menu from which you choose the type of traffic displayed in the plot.
- Refine View icons—These icons let you refine and enhance your view in the network plot and in the site plots.
- Arrange icon—Opens an Arrange palette that lets you move selected nodes and sites into a selected schematic alignment.
- Utilization Color—Traffic utilizations are displayed by colors as a percent of available capacity used on that interface. This enhances the other visual cues, which is the length of the fill. You can change the colors and the utilizations they represent.
Note All traffic is displayed in Mbps. In the network plot, the traffic utilization colors represent outbound traffic.
- Simulation On/Off (white arrow in green circle) icon—By default, any change that voids the current simulation automatically triggers a resimulation. For example, changes in topology trigger a resimulation. To turn off this resimulation, use the drop-down arrow next to the icon to uncheck Auto resimulate.
- Network Options icon—Lets you set global simulation modes, such as Full Convergence or Fast Reroute for MPLS, and whether to include multicast hops. You can also set IGP, BGP, and Multicast protocol options.
- Traffic Levels—Drop-down list of user-defined traffic levels in the plan. For more information, see Traffic Demand Modeling .
- QoS Level—Drop-down list of service classes, interface queues, and undifferentiated traffic. From the Manage QoS option, you can add or edit service classes, assign service classes to queues, and add or edit service policies. For more information, see Quality of Service Simulation .
- Worst-Case Simulation Subset (red X) icon—After a simulation analysis is performed over a specified set of failure scenarios (for example, circuits, nodes, and ports), you can click this icon to select which subset of these failure scenarios (for example, circuits only), as well as service classes you want included in the worst-case analysis. This avoids having to run a second simulation analysis.
- Layouts—Drop-down list of user-defined plots. For example, you might have schematic layouts, geographic layouts, separate layouts for different continents, simplified layouts with hidden nodes or sites, or other representations of the network.
- Plot Options icon—Lets you customize circuit width, text on interfaces, layouts (such as background images and geographic views), and other plot options.
- Legend (question mark) icon—Displays a legend of icons and line types in the plot and their meanings. For more information, see Plot Legend for Design Layouts .
Viewing Plots
WAE Design opens to the main network plot. Although WAE Design shows only the sites in the network plot and tables, you can view those sites in more depth. You can also view more depth of interfaces and demands in their respective plots. In addition to these plot views, you can create and view layouts that show only those portions of the network plot that you choose. For more information, see the Cisco WAE Network Visualization Guide.
Viewing Network Plots
The network plot, also referred to simply as the plot, is the main area showing the network topology. It can contain both sites and nodes.
There are multiple network plot views available (top left of Figure 2-2). The default view is Simulated Traffic. To change the view, select it from the Network Plot View drop-down list in the Visualization toolbar.
- Simulated Traffic—View of simulated traffic that can be used for capacity planning, what-if analysis, and failure planning. Circuits are sized proportional to their capacity. Interfaces are colored according to the percentage of simulated traffic (in comparison to available capacity as defined by the size of the interface or the QoS bound).
- Measured Traffic—View of traffic as measured from live views of the network. Circuits are sized proportional to their capacity. Interfaces are colored according to the percentage of measured traffic (in comparison to available capacity as defined by the size of the interface or the QoS bound).
- Worst-Case Traffic—Interfaces are colored to show the maximum utilization of the interface over all failure scenarios as defined by the most recently run simulation analysis. For more information, see Simulation Analysis .
- Failure Impact—Interfaces and nodes are colored to indicate how a failure of that interface or node would impact other interfaces and nodes. For more information, see Simulation Analysis .
- LSP Reservations—Circuits are sized proportional to their LSP reservable bandwidth. Interfaces are colored according to the percentage of bandwidth (in comparison to what is reserved for the LSP). For information, see RSVP-TE Simulation .
- By editing the plan file directly, you can add a user-defined static view to display interfaces with customized color fills and fill percentages. The view then appears as an option in the Network Plot drop-down list. For information, see the Cisco WAE Design Integration and Development Guide.
Although WAE Design focuses on IP/MPLS Layer 3 (L3) network views and traffic, you can also create and view Layer 1 topologies. To toggle between views of these two layers, choose View > Layer 1 View or View > Layer 3 View, or use the shortcuts Ctrl-1 for Layer 1 and Ctrl-3 for Layer 3. For information, see Layer 1 Simulation .
Viewing Site Plots
The site plot can contain other sites or nodes and their connecting interfaces, including external interfaces that are labeled with their destination node (Figure 2-3).
To open a site plot, do one of the following:
- Double-click a single site from the plot.
- Choose multiple sites from the plot and then double-click one of those sites.
- Right-click one or more sites from the plot or the Sites table and choose Open Site View.
Viewing Interface Plots
The interface plot is a window that displays selected interfaces in a stacked format, making it easier to compare one with another (Figure 2-4).
Step 1 Select one or more interfaces from either the Interfaces table or the plot.
Step 2 Open the interface plot in one of two ways:
Step 3 Work with interface plots in these ways:
- To vertically move the interface list within the plot, click the up and down arrows.
- To view a table of the selected interfaces, click the Adjust button. A new Interfaces table appears.
- To sort the interfaces by ascending or descending order, click the Adjust button. Click a column heading to toggle its sorting between ascending or descending order, then click OK.
The interface plot displays the interfaces according to the sort.
Objects
Other than a site, an object is a representation of elements found in networks, such as nodes (which represent routers), circuits, interfaces, LSPs, and more. A site is also an object, and is a WAE Design construct for simplifying the visualization of a network by grouping nodes within a site, or even by grouping sites within a site.
Objects have properties that identify and define them, many of which are discovered, though they can also be manually added and changed. For example, all circuits have a discovered Capacity property that can be edited. Other properties are derived. For example, Capacity Sim is derived from the Capacity property. Another example is that interfaces have a Util Sim property that identifies the percentage of Capacity Sim the simulated traffic is using. Properties are viewable and editable through an object’s Properties dialog box (right-click the object and choose Properties). They are also viewable as table columns.
Object Selections
Objects are selectable through tables and plots. However, not all objects are selectable from both, though most are. Some object types are only selectable through their tables, such as LSPs.
All selections made in a plot appear in the associated table and vice versa ( Table 2-1 ). Likewise, changes made in the plot are reflected in the tables, and vice versa. Hidden objects are excluded from the selection.
Table 2-1 assumes that all objects are in the foreground. For information on selecting objects that are in the foreground versus background, see Refining Viewable Objects.
Filtering to Selected Objects
To filter only to the selected objects, choose one or more objects in any plot or table, then choose Filter > Filter to Selection. Alternatively, you can press and hold Ctrl-Shift (Cmd-Shift on a Mac), and then double-click.
As with other object selections, to include the nested objects for site selections, add Alt to the selection process. For example, press and hold Alt while clicking one or more sites, and then choose Filter > Filter to Selection.
Filtering to Nested or Parent Objects
If a site contains multiple levels of child sites, you can filter to those nested objects. Right-click a site, choose Filter to Contained <object>, and then choose one of the following, where <object> equals sites, nodes, or L1 nodes:
- Direct—To see only the objects immediately contained within the site.
- All—To see all contained objects, no matter how deeply nested they are within child sites.
If a site contains only one level, the context menu changes to reflect as such.
Conversely, you can find a parent site for any given node. Choose it, and then choose Filter to Sites.
Refining Viewable Objects
View icons are available both in the network plot and in the site plots. Each of these icons makes it easier to find what you need.
Except for Set to Foreground, when accessed through the Visualization toolbar, the view changes apply only to the network plot. When accessed through a site plot, the Zoom, Fit-to-Plot, and Drag actions apply only to that site plot.
Both the Zoom and Set to Foreground icons let you better focus and work in specific plot areas.
Shortcut—Press the letter “z,” which toggles this functionality on and off.
To escape from the Zoomed view, press Esc.
Shortcut—Press the letter “f,” which toggles this functionality on and off.
Shortcut—Press the letter “d” or press the icon again to toggle this functionality on and off. The feature remains enabled until you turn it off.
To escape from the Drag option, either press Esc or click the icon to toggle it off.
- Set to Foreground—Brings selected objects to the foreground for improved viewing while sending all other objects to the background where they appear as if they are transparent. Selected objects must be L3 nodes, L3 circuits, sites, L1 nodes, or L1 links. This feature does not apply to other objects, such as demands, LSPs, L1 circuits, and L1 circuit paths.
To escape the Set to Foreground option, click the icon to toggle it off while objects are selected.
To increase or decrease the transparency (opacity) of how well the background objects appear, click the drop-down arrow next to the Set to Foreground icon. Enter the desired value, and click OK. The higher the value, the denser (darker) the background objects appear.
Note If you are viewing both L3 and L1 objects, this opacity value for background objects takes precedence over the layout opacity value that is set for viewing different layers.
Configuring Preferences
You can configure scaling, foreground and background object preferences, and the background color for layouts.
Step 1 Choose View > Preferences.
Step 2 Click the General tab and configure the following options:
WAE Design considers the settings on circuit and link width in the layouts and scales them accordingly based on the given scale factors in the network plot.
- Enable Selection of Background Objects—If checked, you can select objects in the background.
- Fit to Screen Zooms to Foreground Objects—If checked, clicking the Fit to Screen icon takes into account only the foreground objects. If unchecked, clicking Fit to Screen takes all objects into account.
- Show Tooltips—If checked, tooltips are shown.
One method of seeing related information about an object is to show the tooltips and then hover the mouse over a site, node, L1 node, interface, or L1 link. For example, hovering over a site you can see the number of contained L3 nodes, L1 nodes, and sites, as well as the total number of interfaces connected to the contained L3 nodes.
For example, if in the plot you click a node, and the Nodes table is open, the table scrolls automatically to the row for that node.
Step 3 Click the Layouts tab and configure the following options:
- Schematic Layout—Choose a gray or white background for schematic plots. (If sites or nodes have a white border and the background is also white, a black line appears around them.)
- Geographic Layout—Choose a gray or multi-color palette for geographic plots.
- Use Site, Node, and L1 Node Icons—If checked, icons are displayed for sites, nodes, and L1 node names.
Step 4 (Optional) To save all preferences for future sessions, check Save Preferences.
Step 5 (Optional) To reset the settings back to their default, click Reset. The dialog box refreshes automatically with the default values.
Tables
The tables that are viewable from the WAE Design GUI display a series of rows and columns, where the rows are objects and the columns are properties (Figure 2-5). Plan files also contain other tables that are not viewable from the GUI. These tables contain more complex information, such as showing complex relationships between objects. If you open a plan file using a.txt editor, each table is labeled with angle brackets, such as <Nodes> and <Sites>.
Note For detailed information about plan files and tables, as well as information on creating user-defined columns and tables, see the Cisco WAE Design Integration and Development Guide.
Common Tables
There are numerous tables available for specialized purposes, such as Multicast, P2MP LSPs, and Ports. The tables listed below are the most commonly used and are the defaults.
To bring a table to the forefront and make it the active table, click its associated tab. For example, to open the LSPs table, click the LSPs tab.
- Interfaces—A list of the interfaces in the network.
- Demands—A list of the demands in the network. Each demand specifies how much traffic is routed from a source (node, external AS, or external endpoint) to a destination (node, external AS, external endpoint, or multicast flow destination).
- Shortest Paths—A list of the routes between selected sites.
- Nodes—A list of network routers, which typically have names that suggest their location and function. For example, node cr1.atl is core router 1 in the Atlanta site.
- LSPs—A list of MPLS LSPs in the network; each LSP contains both a source and destination. Note that sub-LSPs within point-to-multipoint (P2MP) LSPs are listed in the LSP table.
- Sites—A list of network sites.
- SRLGs—A list of the shared risk link groups (SRLGs); an SRLG is a group of objects that might all fail due to a common cause.
- AS—A list of both internal and external autonomous systems (ASes). An AS is a collection of connected IP routing prefixes that are controlled by one operator.

Showing or Hiding Tables or Columns
Searching and Filtering in Tables
Most WAE Design tables, whether below the network plot or with dialog boxes, have an empty Search field in the top right as shown in Figure 2-5. Likewise, they usually have a Filter control menu that opens a Filter dialog box specific to that table. Figure 2-6 is an example of an Interfaces Filter dialog box.
|
|
---|---|
1. If you are not in a dialog box, show the table whose objects you want to search. 2. In the Search field, enter a search string and press Enter. |
|
Filter the table to a list of specific search values, and either replace, add to, or narrow the list of objects currently showing in a table. |
1. If you are not in a dialog box, show the table whose objects you want to filter. 2. Click the Filter control menu button (Figure 2-6). 3. Choose from the drop-down lists and enter search criteria. 4. If you are filtering by more than one criterion, you can optionally use these controls: – Match All—(Default) Filters to only those rows that match all the specified criteria (default). – Match Any—Filters to rows that match any one of the criteria. 5. Select whether to replace, add to, or narrow the list of objects currently showing in a table. – Replace—Replaces objects showing in the table with those found in the search (default). – Union—Adds the objects found to those showing in the table. – Intersection—Filters to (search for) objects only within those objects that are currently showing in the table. |
Filter the selection to associated objects. For example, you might want to filter a circuit to associated interfaces. |
Choose Filter > Filter to X, where X is a name of a viable object. |
Toggle whether to change the filter selection with or without first asking. |
Choose Filter > Interaction with current filter > X, where X is either Always Ask or Replace. |
Saving Table Settings or Restoring Defaults
Other Table Actions
Context Menus
WAE Design has a hidden menu called a context menu. Anywhere that you right-click, whether it is in an empty area in the plot, on an object in the plot, on a table tab, or on a column or row in a table, a context menu appears with available options based on where you clicked. The context menu does not apply only in the main menus and in the Visualization toolbar.
The most common use case for context menus is for filtering to related objects. For example, to find the L1 circuits mapped to an L3 circuit, right-click the L3 circuit and choose Filter to L1 Circuits. You can select multiple objects and right-click just one to find the related information for all selected objects. If you want to see only selected objects in a table, right-click one of the selected objects and choose Filter to Selections.
If in a site, an interface, or a demand plot, the right-click actions taken affect the network plot.
Log and Report Windows
The following additional windows are displayed using menu items or after running tools:
- Log window—This window appears automatically when warnings or errors are logged. You can view these by choosing Window > Log window.
- Reports—Reports are generated through the Tools > Reports menu, as well as automatically when running certain tools such as Simulation Analysis. The report window appears at that time, and is accessible later by choosing Window > Reports. For more information, see Reports .
