Working with Prime Network Vision Maps

The topological map is the main tool used by Cisco Prime Network Vision (Prime Network Vision) to display the links and relationships between the network elements and aggregations. The following topics describe how to work with the topological maps displayed in the content pane of the Prime Network Vision window:

•User Roles Required for Working with Prime Network Vision Maps

•Opening and Closing Maps

•Creating and Deleting Maps

•Adding and Removing NEs from Maps

•Managing Maps

•Finding NEs, Services, and Links, and Elements Affected by Tickets

•Working with Aggregations

•Working with Overlays

•Filtering Links in a Map

•Opening the CPU Usage Graph

•Communicating with Devices Using Ping and Telnet

You can also perform the following functions from the map and list views if they are configured for your client:

•Launch external applications or tools, such as an SSH client.

•Launch available scripts and commands, depending on the NE device type, OS, supported technologies, and so forth. Those commands are documented throughout this guide (for example, Setting Up Devices and Validating Device Information). This also includes commands you create using Command Manager and Command Builder. A list of scripts is provided in Cisco Prime Network 4.0 Supported VNEs - Addendum.

User Roles Required for Working with Prime Network Vision Maps

This topic identifies the roles that are required to work with Prime Network Vision maps. Prime Network determines whether you are authorized to perform a task as follows:

•For GUI-based tasks (tasks that do not affect elements), authorization is based on the default permission that is assigned to your user account.

•For element-based tasks (tasks that do affect elements), authorization is based on the default permission that is assigned to your account. That is, whether the element is in one of your assigned scopes and whether you meet the minimum security level for that scope.

For more information on user authorization, see the Cisco Prime Network 4.0 Administrator Guide.

The following tables identify the tasks that you can perform:

•Table 5-1 identifies the tasks that you can perform if a selected element is not in one of your assigned scopes.

•Table 5-2 identifies the tasks that you can perform if a selected element is in one of your assigned scopes.

By default, users with the Administrator role have access to all managed elements. To change the Administrator user scope, see the topic on device scopes in the Cisco Prime Network 4.0 Administrator Guide.

Opening and Closing Maps

Whenever you open a map, the network information is automatically refreshed. For example, if a device was up the last time that the map was saved and closed, and then the device is moved to maintenance, the next time you open the map the management status of the device is updated accordingly and the device displays a maintenance status.

When you first log in, Prime Network Vision lists the maps you recently viewed but did not close when you exited the session. You can also open other maps by choosing File > Open, which displays the Open Map dialog.

By default, you can view and work on a maximum of five maps at any given time (per client instance) in the Prime Network Vision window. To change this default setting, contact your Cisco account representative. To create a new map or select a new map, close the required number of maps.

You can save maps as images or print them, if desired.

To close a map, choose File > Close. Prime Network Vision saves basic map information whether or not you manually save the map. This default information includes device and link additions, device and link removals, aggregations, and disaggregations. If you made any changes that will not be saved, Prime Network Vision prompts you to save the map.

Creating and Deleting Maps

You can create maps that cover specific network segments, customer networks, or any other mix of network elements required. Network maps provide a graphic display of active faults and alarms, and serve as access points for activating services. When you create a map, it is saved in the database and made available to other users if they have sufficient access and security privileges. When you delete a map, it is removed from the database. See these topics for more information:

•Creating New Maps

•Deleting Maps from the Database

Creating New Maps

To create a new map, choose File > New Map in the main menu. The following figures give examples of how you can create and manipulate maps. To add NEs to maps, see Adding and Removing NEs from Maps.

Link Filters

Link filters let you choose the links in which you are interested, and then build a map that only displays NEs using those link types. Examples are physical links, data links, MPLS, VLANs, and so forth. When you open the New Map dialog, click the Advanced button and choose the types you want to display.

Figure 5-1 Map with Link Filter

To create a map with link filters, see Figure 5-13.

Aggregations

Aggregations are user-defined groups of elements. An aggregation can contain network elements, services, other aggregations, and so forth. Figure 5-2 shows an example of an aggregation.

Figure 5-2 Map with Aggregation (Thumbnail View)

When you delete an aggregation, the member devices are not deleted from Prime Network; only the aggregation definition is deleted. To create an aggregation, see Working with Aggregations.

Overlays

Overlays isolate the parts of a network that are being used by a specific service, such as an ethernet service or network clock. Figure 5-3 shows an example of an Ethernet Service overlay, where the ethernet link is using the service.

Figure 5-3 Map with Overlay

To create an overlay, see Working with Overlays.

Deleting Maps from the Database

If another client is using a map that you are deleting, Prime Network Vision displays a message to those clients advising them that the map is being closed and deleted from the database.

To delete a map from Prime Network Vision and the Prime Network Vision database:

Step 1 Open the Open Map dialog by choosing File > Open.

Step 2 In the Open Map dialog box, complete the following steps:

a. Select the map you want to delete.

b. In the toolbar, click Delete Map. A confirmation message is displayed.

c. Click Yes. The selected map is deleted from the Open Map dialog box, the Prime Network Vision window, and the database. If the map is open when you click Yes, a message is displayed, stating that the map will be closed.

d. Click OK to acknowledge that the map can be closed.

e. Click Cancel to close the Open Map dialog box.

Adding and Removing NEs from Maps

When you add an element to a map, the map is automatically saved in the Prime Network Vision database

If the element you want to add is outside of your scope, it is not displayed if you enter a search string. You can display all NEs by selecting Show All in Step 2, but devices outside your scope will be displayed with a lock icon.

To add an element to a map:

Step 1 Choose File > Add to Map > element.

Figure 5-4 shows the type of elements you can add to maps.

Figure 5-4 Available Elements to Add to Maps

If you choose to add a new VPN, the Create VPN dialog box is displayed. For information on creating a VPN, see Creating a VPN.

In all other instances, the Add element to map dialog box is displayed, as shown in Figure 5-5.

Figure 5-5 Add Element Dialog Box

Step 2 In the Add element dialog box, do one of the following:

If you are working with a very large number of network elements, keep these items in mind:

•Search for the elements you want to add to the map. For example, you can search Ethernet Services by the system name, NEs element type, pseudowires by their role, and so forth.

Note If you are working with a large number of NEs, using the search filter Otherwise, it may take some time for all of the NEs to be listed.

•To view all available elements, choose Show All.

The available elements are displayed in the Add element dialog box in table format. The dialog box also displays the date and time at which the list was generated. To update the list, click Refresh.

If a network element is not included in your scope, it is displayed with the locked device icon.

Step 3 In the Add element dialog box, select the elements that you want to add. You can select and add multiple elements by pressing Ctrl while selecting individual network elements or by pressing Ctrl + Shift to select a group of elements.

Step 4 Click OK. If you selected a large number of elements (for example, more than 25 VLANs or VPLS instances), the action may take a while to complete.

The NEs are added to the map and are displayed in the navigation pane and content area. In addition, any associated tickets are displayed in the ticket pane.

Removing Elements from a Map

When you delete an element or aggregation from a map, it is removed from the map in the database, but the elements are still managed by Prime Network Vision.

Note Based on the security level and access permissions assigned, this option might not be available to all users.

To remove a network element or aggregation from a map:

Step 1 In the navigation pane or map, select the element or aggregation that you want to delete.

Step 2 Right-click to display the right-click menu and choose Remove from Map. The selected element or aggregation is removed from the map.

The element is removed from the map in the database, but is still managed by Prime Network Vision and can be added again.

To save these changes, click Save Map Appearance in the main toolbar, then click OK. The map is saved as an image in the directory you specified.

Finding NEs, Services, and Links, and Elements Affected by Tickets

The following topics describe how to find network elements, services, links, or elements affected by a ticket in Prime Network Vision maps.

Table 5-5 Aggregation Thumbnail Options

If you want to find...

Do this...

An NE or service

From the Prime Network Vision main menu, choose Edit > Find in Map. Enter an element or service (such as a VPN or VLAN) by entering any part of its name or device IP address. If you want your search to include aggregations, check the Search all map levels check box.

A link

From the Links view, right-click the link and choose Find Link in Map. The link is highlighted in the map pane. If two or more lines represent the same link (such as a VRF link), you can choose the appropriate one.

If more than one edge device contains the same link in the same map or context, all related edge devices are selected in the map.

Which NEs are affected by a ticket

In the ticket pane, right-click the required ticket and choose Find Affected Elements. If only one element is affected, the affected element is selected in the navigation pane and the content area; if a link is affected, the affected link is selected in the links view.

If two or more elements are affected, the affected elements are displayed in the Affected Elements window.

Working with Aggregations

Prime Network Vision enables you to group network elements and display them as an aggregation. Aggregations can contain network elements, services, other aggregations, and so forth.

Note You cannot aggregate service entities that exist within a service. For example, you cannot aggregate VRFs that exist within a VLAN.

For more information on working with aggregations, see the following topics:

•Grouping Network Elements into Aggregations

•Adding Elements to an Existing Aggregation

•Viewing an Aggregation Thumbnail

•Ungrouping Aggregations

•Viewing Multi-Chassis Devices

Grouping Network Elements into Aggregations

To aggregate network elements:

Step 1 Select the network elements. To select multiple items, press Ctrl.

Step 2 Aggregate the network elements by choosing Node > Aggregate.

Step 3 In the Aggregation dialog box, enter a unique name for the aggregation and click OK. The aggregation is displayed in the navigation pane and the map pane. Aggregations are displayed as a single entity with the Aggregation icon and a plus sign, as in the following examples:

The aggregation icon changes color according to the alarm severity. For more information about severity colors, see Alarm Indicators.

Viewing an Aggregation Thumbnail

You can view a thumbnail of a selected aggregation in the map pane, including all aggregated elements and any nested aggregations.

To display an aggregation thumbnail:

Step 1 Select the existing aggregation in the map pane.

Step 2 Open the thumbnail by right-clicking the aggregation, and choosing Show Thumbnail.

The thumbnail is displayed in the map pane as shown in Figure 5-8.

Figure 5-8 Aggregation Thumbnail

When a thumbnail is opened, neighboring nodes are moved aside by default to allow room for the thumbnail to expand. Similarly, when a thumbnail is closed, the neighboring nodes usually return to their original locations. This behavior of the neighboring nodes when a thumbnail is opened and closed is configured in the registry, and can be disabled, if required.

A dashed gray border around an icon indicates that the element resides within a thumbnail and not at the current map level.

Table 5-6 describes the options available when working with aggregation thumbnails.

Table 5-6 Aggregation Thumbnail Options

If you want to...

Do this...

Rearrange the icons in the thumbnail

Click and drag the required icons to arrange them as needed.

Resize an icon

Select the icon to be resized, and then either click and drag the gray border or right-click a selected icon and choose Resize.

The right-click Resize option allows you to resize multiple selected icons at the same time.

Resize the thumbnail frame

Click and drag one or more icons. If you drag an icon beyond the thumbnail frame, Prime Network Vision adjusts the thumbnail size automatically.

View a nested aggregation

Click the nested aggregation plus sign.

View only the aggregation in the map pane

Double-click the thumbnail frame.

View the next higher level in the map pane

Double-click the current map background.

Zoom in or out in the thumbnail

Position your mouse cursor in the map and use the mouse scroll wheel to zoom in or out.

Step 3 To close the aggregation thumbnail, right-click the thumbnail frame and choose Show As Aggregation.

Adding Elements to an Existing Aggregation

You can add elements to an existing aggregation at any time. When adding elements to an aggregation, keep in mind that certain restrictions exist. For example, you cannot add an EVC to a VLAN.

To add elements to an existing aggregation:

Step 1 Select the existing aggregation in the map pane.

Step 2 Open the thumbnail by right-clicking the aggregation, and choosing Show Thumbnail.

Step 3 Double-click the thumbnail frame to view the aggregation at the map level.

Step 4 Click Add to Map to add the required element to the aggregation.

Step 5 Return to the map by double-clicking the map background.

Ungrouping Aggregations

Aggregations can be ungrouped. If the aggregation that you ungroup contains nested aggregations, the nested aggregations move up one level, and the original aggregation is removed.

If an element in the aggregation that you ungroup also exists at the parent level, the element is represented only once after the aggregation is ungrouped. As a result, no elements are represented twice at the same level.

To ungroup an aggregation:

Step 1 Select the required aggregation in Prime Network Vision.

Step 2 Ungroup the node by selecting the aggregation in the map pane and choosing Node > Disaggregate.

If the aggregation contains elements that already exist at the parent level, a confirmation message is displayed, stating that any duplicate elements will be removed.

Step 3 Confirm the disaggregation. The node is disaggregated. Any aggregations in the selected node move up one level, and the original aggregation is removed.

Viewing Multi-Chassis Devices

Using Prime Network Vision, you can view the physical layout and topology among the multi-chassis devices on the map. The multi chassis devices are grouped as an aggregation and are displayed as a single entity with a plus sign on the map as show in Figure 5-9. The plus sign can be expanded to display the devices under the group as shown in Figure 5-10.

You can see the multichassis grouping in the map view for network elements such as Cisco Aggregation Service Router (ASR) 9000 series network element and Cisco Unified Computing System (UCS). If satellites are configured for a Cisco ASR 9000 series network element, you can view the satellites grouped with the other chassis. For more information on how to view satellite properties, see Viewing Satellite Properties.

The physical ethernet links used for connecting the multi chassis devices are ICL (Inter Chassis Link) and IRL (Inter Rack Link). For more information on when each of these links are used, see Viewing Inter Rack Links and Viewing Inter Chassis Links.

Figure 5-9 Multichassis Devices in Map View

Viewing Inter Rack Links

Inter Rack Links (IRLs) are used to represent connectivity between the cluster hosts, Cisco ASR 9000 network elements.

Figure 5-10 Multiple Chassis in a Cluster

To view the cluster IRLs:

Step 1 In Prime Network Vision, double-click the cluster device to open the Inventory Window for the device.

Step 2 Choose the Cluster IRL container in the logical inventory of the cluster device. The content pane displays a list of cluster IRLs with the following details:

•A End Point—Device or site that is the source of the link, hyperlinked to the inventory of the device or site.

•Z End Point—Device or site that is the destination of the link, hyperlinked to the relevant entry in the inventory.

Viewing Inter Chassis Links

Inter Chassis Links (ICLs) are used to represent the connectivity between the host Cisco ASR 9000 network element and the satellites. One or more satellites are connected to the host Cisco ASR 9000 series network element by using the ICLs. Figure 5-11 shows an ICL in the map view.

c. Enter a search string to narrow the display to a range of overlays or to a specific overlay. Table 5-8 identifies the search categories available for each type of overlay.

d. Click Go.

Search strings are case-insensitive. If you choose Name and enter NET, the overlays that contain "net" in their names are displayed. If you choose System Name and enter System123, only the overlay with the system named System123 is displayed.

•To view all available overlays, choose Show All.

The available overlays that meet the specified search criteria are displayed in the Select Overlay dialog box in table format. The dialog box also displays the date and time at which the list was generated. To update the list, click Refresh.

Step 4 Select the overlay that you want to apply to the map.

The elements and links that are used by the overlay are displayed in the map, and the overlay name and date are displayed in the toolbar, as shown in Figure 5-13.

Figure 5-13 Overlay Example

Note The overlay is a snapshot taken at a specific point in time and does not reflect changes that occur in the service. As a result, the information in an overlay can become stale. To update the overlay, click Refresh Overlay in the toolbar.

Hiding and Viewing Overlays, and Removing Overlays from a Map

When an overlay is applied to a map, the Show Overlay/Hide Overlay button becomes active in the toolbar. To hide and view the overlay, click Hide Overlay/Show Overlay in the toolbar. The button toggles depending on whether the overlay is currently displayed or hidden.

To remove an overlay, choose Choose Overlay Type > None. The overlay is removed from the map.

Filtering Links in a Map

The links filter enables you to filter the links displayed in the map view and the links view. You can quickly select the types of links to be filtered by selecting from a predefined set of link types in the list, or by manually configuring a customized set of link types.

To filter links, do either of the following:

•Create a new map, select a filter, and then add the devices to the map. This filter is applied to the new map and only the required link types are visible in the map view and the links view. For more information, see Filtering Links During Map Creation.

•Create a map and add the devices with all links enabled and visible in the map view and links view. You can then filter (display or hide) the different types of links as required. For more information, see Filtering Links in an Existing Map.

The links filter applies to all aspects of Prime Network Vision: the map view, links view, ticket pane, severity calculation, and other items, such as memory consumption and thresholds. Prime Network Vision holds only the links that are relevant to the filter and synchronizes the links with the gateway according to that filter.

For more information about links in Prime Network Vision, see Chapter 6 "Working with Links."
