Interactive Map Features Overview

 

The topology map is interactive which means you can use features within the map to customize the map and the network information table. The map uses a geographic coordinate reference system. Some features enabled by that system include:

  • Constrained zooming: Controller performs coordinate checking so the view is constrained to the coordinates on the earth.

  • World wrapping/map wrapping: Scrolling the map in one direction is like spinning a globe. For example, this enables representation of links across an ocean.

Right-Click Functions

You can right-click a node, node group, link, or blank space on the topology map to access context-specific menus.

Table 1 describes the options displayed when you right-click over any blank space on the topology map.

Option

Description

Grouping

You can view, group, or ungroup nodes in a node group.

Nodes & Groups

Displays the nodes and node groups in the topology. You can select a particular node group to be displayed on the topology map.

Auto Grouping

Allows you to specify criteria used to automatically group nodes. For more information, see Auto Grouping Nodes.

Group Selected Nodes

Groups the selected nodes. For more information, see Group Nodes.

Ungroup Selected Nodes

Ungroups the nodes from the selected group. For more information, see Ungroup Nodes.

Ungroup All

Ungroups the nodes in all groups.

Select All Nodes

Selects all nodes on the topology map. This is a shortcut to using shift-left-click to create a selection box around all nodes or individually shift-clicking on all nodes.

Show All Nodes and Links

Restores the topology map so it includes all nodes and links in the network, as opposed to a filtered subset.

Save to Default Map Layout

Save the current layout as the default. This action saves the current layout as your default, but does not change the name of the default in the Manage Layouts page.

Layout

Manage Map View

Save, load, or edit the current topology map. For more information, see Manage Map Layouts.

Distribute All Nodes

Select multiple nodes on the topology map and redistribute them to improve visual clarity or for personal preference. Distributes all the nodes in the map, pushing elements away from each other and minimizing overlap.

Distribute Selected nodes

Forces the selected elements away from each other and minimizes overlap.

Circle selected nodes

Arranges the selected nodes in a roughly circular pattern with the nodes and links separated as much as possible.

Straighten selected nodes

Aligns the selected nodes in a linear pattern.

Reset by Coordinates

Resets the map to display the nodes based on their configured coordinates (latitude and longitude).

Note: You can reset the distribution of nodes on the topology map according to geographical coordinates if you have set the latitude and longitude values of the nodes. It can be useful to have the country map backdrop displayed when you use this distribution model.

Set Coordinates from Map

Reconfigures the node coordinates based on their current locations on the map.

Import from

Subview

Filters the network elements on the topology map based on Node Type, Autonomous System (AS) number, OSPF Area, ISIS Area, Layer, or Admin Group. For more information on these options, see Table 2.

Timeline

Lists activities and status checkpoints with the most recent activity first.

You can use the search box at the top of the Timeline drawer to highlight specific events. You can use the up and down arrows to move to the next or previous event (search result), or click the Top arrow (at the bottom-right corner of the drawer) to move back to the topmost event in the timeline.

You can also refresh the timeline events by clicking the refresh button at the bottom-left corner of the page.

You can assess the stability of the MPLS network by tracking changes in the number of LSP Up and Down events over time. You can then analyze whether the occurrence of specific other events affects the number of LSP Up and Down events.

The following event types are included in the Timeline:

Event types related to nodes:

  • PCEP session goes Down

  • PCEP session goes Up

  • PCEP session becomes ACTIVE

Event types related to links:

  • Link goes Up

  • Link goes Down

Event types related to LSPs:

  • Change in the number of LSPs that are Up

  • Change in the number of LSPs that are Down

  • Change in the number of LSPs that are being provisioned

Even types related to Controller:

  • Path optimization start and end times

  • Maintenance events start and end times

Pause/Resume Network Event Processing

Click to pause or resume the processing of network events. When paused, the network information table and topology map is not refreshed in response to network events until you select Resume Network Event Processing. However, network events continue to be processed in the background but they are not refreshed in the UI.

This is beneficial in large networks where the processing of network events results in frequent UI updates.

Reload Network

Reloads the network and updates the displayed topology map.

Options

Description

Node Type

Select the Node Types from the list.

AS

Assign a color to represent each AS number configured on the topology map.

From the AS pane, you can select or clear AS numbers by selecting or clearing the corresponding check boxes. Only nodes corresponding to selected AS numbers are displayed in the topology map.

ISIS Area

Assign a color to represent each IS-IS area identifier configured on the topology map. The area identifier is the first three bytes of the ISO network entity title (NET) address.

From the ISIS area pane, ISIS area identifiers can be selected or cleared by selecting or clearing the corresponding check boxes. Only nodes corresponding to selected area identifiers are displayed in the topology map.

OSPF Area

Assign a color to represent each OSPF area configured on the topology map. NONE shows the color assigned to routers with no OSPF area configured.

From the OSPF Areas pane, Select or clear OSPF areas by selecting or clearing the corresponding check boxes. Only nodes corresponding to the selected OSPF areas are displayed in the topology map.

Layer

Include or exclude individual layer information in the topology map.

From the Layers list, select the layers (IP, Transport, or both) that you want to display. If you are not using the Multilayer feature, the Layers list contains only IP.

Admin Group

Provides bit-level link coloring options so that you can easily differentiate the different links displayed in the topology map.

Admin Group includes manually assignes bit-level attributes that describe the color of links (up to 32 names/values from bit 0 to bit 32). There are three conditions you can filter by (all, any, or not). Links with the same color conceptually belong to the same class. You can use this to implement a variety of policy-based label-switched path (LSP) setups. For more information, see Assign Names to Admin Group Bits.

Table 5 describes the tabs on the topology settings pane.

Table 5: Topology Settings Options

Tab

Description

Nodes

You can do the following:

  • Change the labels of all nodes on the topology map by selecting an option from the Label list.

  • Once you select a label, click the toggle button to show:

    • Background shadow of node labels

    • Pseudo node label

    • Only favorite node labels

    • Isolated nodes

    • Overload bit marker

Links

You can do the following:

  • Change the labels of all links on the topology map by selecting an option from the Label list.

  • Click the toggle button to:

    • Show or hide link down markers

    • Draw down links as a dashed line

    • Draw a link line width in proportion to the interface speed

    • Draw parallel links as a curve: Toggle the button to draw parallel links between two nodes as a curve, so that the parallel links are not overlapped and appear separately (as curves) on the topology map. If the parallel links between two nodes are drawn as straight lines, they would overlap on the topology map (as a bundle).

      • Show utilization max instead of Average within bundle: Toggle this button to display the maximum utilization value (in red) instead of average utilization value for parallel links. For example, if there are two parallel links between two nodes, one link has 10% utilization and the other has 20% utilization, and you want to draw the link as a straight line between the nodes, you can choose which utilization value should be displayed: 15% (average) or 20% (maximum) value.

      • Show Count of the bundle: Toggle the button to display (in green) how many links are present between the two nodes.

    • Wrap links as great arcs: Distinguishes links that would have to wrap around the world map

      An example is shown in Figure 1.

      Figure 1: Wrap Links as Great Arcs Example
      Wrap Links as Great Arcs Example
    • Hide Partially Visible links: Hides any link whose end nodes are outside the visible area. This is useful for focusing on a subset of a large network.

Note: The topology map does not display node or link labels over a certain quantity, even if the Topology Settings call for labels to be displayed. This improves performance when redrawing a large number of graphic elements.

Tunnels

You can do the following:

  • Click the toggle button to draw a path as a curve which might improve network visualization.

    Figure 2 shows both curved and straight lines for the same path.

    Figure 2: Curved and Straight Line Path Depiction

Path Depiction
  • Click the toggle button to draw path through layers if the network includes transport layers.

General

You can do the following:

  • Click the toggle button to:

    • Enable animation while calculating the topology layout.

    • Show or hide maintenance marker: Displays a red M over any link that is a part of an active maintenance event.

    • Show or hide zoom slider: A vertical slider is displayed on the topology menu bar on the top right corner of the topology window.

    • Enable or disable to zoom to selected node: With this option enabled, when you click the node entry in the network information table (Node tab), the topology automatically centers the view on that selected node.

  • Select a Label Size: Select one of the following as the font size for node and link labels:

    • 8

    • 10

    • 12

    • 14

    • 16

    • 18

    • 20

  • Apply Opacity effects: Move this slider to select the percent opacity for unhighlighted topology map elements. Figure 3 shows 100% and 20% opacity for comparison.

  • Show World Map: You can select the type of map (based on color or labelling) to be displayed on the Topology page. Based on the selection made, the topology map is updated immediately. You can select one of the following options:

    • PathFinder—Displays the topology on the world map.

    • PathFinder No Labels—Displays the topology on the world map without highlighting the city/country names.

    Note: Based on the license purchased, you can also select one of the following world map options:

    • OpenTopoMap—Detailed color world map.

    • Stamen Toner—Detailed black and white world map.

    • Stamen Toner-lite—Detailed world map with a white background.

    • Stamen Toner no labels—World map with white background without highlighting the city/country names.

    • Even if you deselect Show World Map, the topology still is displayed according to the geographical coordinates (in terms of displaying the topology within the field of view).
