7-17 Cisco Prime Network 4.3.2 User Guide Chapter 7 Viewing Devices, Links, and Services in Maps Finding Services Using Map Overlays Figure 7-9 Aggregation Thumbnails This table lists the ways to move between aggregations and parent maps. Finding Services Using Map Overlays When you apply an overlay to a map, you can isolate the parts of a network that are being used by a specific service such as VPLS, network pseudowire, MPLS-TP tunnels, and so forth. Prime Network models and manages many more technologies and services which you can view from a device’s inventory window. Those technologies and services are described in other topics in this guide. If you want to... Do this... View and drill into only the aggregation (not other NEs in the map)Double-click the thumbnail frame (or the aggregation itself, if it is closed) From an aggregation, go up one level (parent level) Double-click the inner level background Open and close thumbnail Click the plus/minus sign at the top right of the aggregation

7-20 Cisco Prime Network 4.3.2 User Guide Chapter 7 Viewing Devices, Links, and Services in Maps Viewing and Managing Links Figure 7-11 Clock Service Overlay Example Hiding and Removing Service Overlays from a Map To temporarily hide an overlay or remove it completely: Temporarily hide a map overlay by clicking Hide Overlay/Show Overlay in the toolbar. The button toggles depending on whether the overlay is currently displayed or hidden. Delete an overlay from the map by choosing Choose Overlay Type > None. Viewing and Managing Links Links are the physical and logical connections that exist between elements in the network. You can get link property information for links that are: Between two devices. Between a device (Device A) and an aggregation, where a device inside the aggregation is connected to Device A. Between two aggregations that contain devices that cross the aggregations. In Vision client maps, a single link can actually represent multiple links—for example, a physical ethernet link and an MPLS link. Drill down into the link to get this information. These topics explain how to manage links using the Vision client: Using Link Filters to Find Links, page 7-21 Interpreting Link Colors, Widths, and Symbols, page 7-21 Viewing Link Details, page 7-22 Checking the Impact of Link Problems (Impact Analysis), page 7-27 Managing Missing Links (Static Links), page 7-29
7-21 Cisco Prime Network 4.3.2 User Guide Chapter 7 Viewing Devices, Links, and Services in Maps Viewing and Managing Links Using Link Filters to Find Links Use a link filter when you want to locate specific link types, such as physical links, VPN links, data links, and so forth. Sometimes it may not be clear if a link filter is already applied to a map. To verify whether a map is using a link filter, check the map toolbar. To create a link filter: Step 1Click Link Filter in the main toolbar. Step 2Select the specific links you want to view, or select a links group from the drop-down list. Step 3Click Apply and OK. If any links are grey, it means you do not have sufficient permissions to view them. By default, the Vision client only displays a link if you have permission to view both of the link’s end points. If you want to remove the filter later (and show all links), repeat the previous steps but choose All from the group drop-down list. Step 4To interpret the information displayed by the Vision client, see Viewing Link Information Displayed at the Map Level (Tool Tips and Quick View), page 7-23. Interpreting Link Colors, Widths, and Symbols The following tables provide keys for understanding the link information displayed by the Vision client. Link Colors: A link filter is applied to the map. To clear the filter, click this icon and choose None from the Group drop-down list. A link filter is not applied. To apply a link filter, see Using Link Filters to Find Links, page 7-21. To display these links: Choose Data links (ATM, Frame Relay) Data Physical layer links Physical VPN links (GRE, Pseudowire, VPN, VPN IPv6) VPN Link types that you want to choose (your choices will be saved for the next time you open the link filter)Custom All links All Link has a critical alarm Red Link has a major alarm Orange Link has a minor alarm Yellow

7-24 Cisco Prime Network 4.3.2 User Guide Chapter 7 Viewing Devices, Links, and Services in Maps Viewing and Managing Links The link quick view in Figure 7-13 provides the following information. View Links at Different Levels in Aggregations and Maps (Links View) You can launch a links view from a map or from an aggregation thumbnail. When you open the links view, it shows links at the current level and for all nested aggregations (all links must have both endpoints in the map or aggregation). To open a links view, click Show Links View from the main toolbar. Figure 7-14 shows an example of the links view launched from a map view. NoteIf some links are missing, your map may be using a link filter. To clear a link filter, click Link Filter, choose All from the group drop-down box (to display all links), and click Apply and OK. Figure 7-14 Links View 1Number of links represented by the single link in the map (in this example, 27 links). 2Link endpoints. 3List of all links represented by the link, including the link type, detail, and alarm status (color). This example shows 3 pseudowire links and one physical link. 4Hyperlink to the link properties window. The Properties button is available for physical, topographical, and service links, but is not available for business links (dashed links). See Viewing Link Status and Detailed Link Properties, page 7-25.
7-25 Cisco Prime Network 4.3.2 User Guide Chapter 7 Viewing Devices, Links, and Services in Maps Viewing and Managing Links Note the following: The context field may be empty if one side of the link is not included in the map, or the link is filtered out of all contexts. A blue background indicates an external link (a link with only one endpoint in the map or aggregation). The A End-Point is the element or site that is the source of the link; The Z End-Point is the destination. For unidirectional links, traffic is from A to Z. NoteIf you load a map with many links (for example, thousands of links), it can take a while for the complete list of links to load. The filtering options in the table are unavailable until the table has completely loaded. The links view provides buttons that allow you to traverse among link levels, as follows: Viewing Link Status and Detailed Link Properties To view link details, click the link (it will turn blue), then right-click the link and choose Properties. As shown in Figure 7-15, the link properties window provides general information about the selected link, details of the link connection, and technology-specific information appropriate for the link. If multiple links exist between the elements or aggregations, the link properties window displays information for all the links. Table 7-1 Ways to Traverse Link Levels To do the following: Do the following, or click icon: View a link in a map Right-click link and choose Select Link in Map (link will be blue) View all link properties (see Viewing Link Status and Detailed Link Properties, page 7-25)Right-click link and choose Properties Display all links the map or selected aggregation, including external links (All Links icon). Display links that have only one side in the selected map or aggregation (External Links). (These are indicated with the blue background in the previous figure.) Display links in the selected map or aggregation, excluding links in any closed aggregations (Flat Links). Display for the selected aggregation and any nested aggregations with both endpoints in the map or aggregation (Deep Links). This is the default.
7-26 Cisco Prime Network 4.3.2 User Guide Chapter 7 Viewing Devices, Links, and Services in Maps Viewing and Managing Links Figure 7-15 Link Properties Window The links listed on the left display the left and right link identifiers between the two nodes, the device alias, and the Connection Termination Point (CTP). When you select a link, the properties area is populated with extensive information about the selected link, most of which is self-explanatory. These items are especially important: Under General Properties, the type can be either dynamic or static. –Dynamic links are real links between devices or aggregations. –Static links are not real links, but are created by Prime Network advanced users to represent a real link (for example, when a real link is not discovered). Static links provide allow Prime Network to perform correlation flows through the link. Link status is displayed under the Connection Information. Speed, port type, port admin and operational status, and other information is displayed for connections of types such as Ethernet CSMA/CD, Gigabit Ethernet, LAG, MLPPP, MP-BGP, MPLS Link Information, PPP, Pseudowire, T1, and VRF. Users with advanced privileges can click Calculate Affected to see which resource pairs would be impacted by a problem with the link. (If the link had a ticket, the same information would be automatically generated and displayed in the ticket under the Affected Parties tab.) See Checking the Impact of Link Problems (Impact Analysis), page 7-27.
