Working with Topology Maps
The Cisco ANA Monitoring Perspective provides views that allow you to perform operations on a group of network elements. The topology map displays the status of the network elements and the connectivity between them. The topology map is used as a general dashboard to view the network elements, their status, the relationships between them, and the alarms that are raised on them.
You can create multiple topology maps to represent specific network views. Views can cover specific network segments, customer networks, or any other mix of network elements desired. Once the maps have been created, they are available for all connecting Cisco ANA clients.
The Cisco ANA Topology module allows you to:
•
View network inventory and multilayer connectivity.

Cisco ANA provides functionality for displaying and managing the topology maps by providing:

Roles Required for Managing Maps
Table 5-1 lists the roles that are required for managing maps. For more information on roles, see Creating and Managing Users, Passwords, and Scopes, page 14-34.

Understanding Static and Dynamic Links
The Cisco ANA Topology module enables you to manage the links between network elements and to add a new static link between them.
A dynamic link is a link that is detected by Cisco ANA and connected automatically. A static link is a link that you can manually create.
When adding a new link the state of the link reflects its current state. For example, if the operation status of a port is down, the link is colored red.
For information on creating static and dynamic links, see:

Creating a Map
You must create a new map, or open a map that was previously saved, to display the network. The Cisco ANA Topology module supports the creation of multiple topology maps to represent specific network views. The topology maps provide a graphic display of Alarm severity, network element management state, and VNE state. See Network Element and Map Decorators, page G-2 to understand the network element icons that are displayed in the map.
You can create a new map, and then add the network elements to the map. You cannot define the same name for two or more maps.
To create a map:
Step 1
Step 2
Step 3
You can use alphanumeric values. The minimum map name length is 1 character and the maximum is 65 characters. The only special characters you can enter are an underscore (_) and dollar symbol ($).
Step 4
You can add a maximum of 999 network elements to a map.
The list of network elements that you have selected is displayed in the Summary workspace.
Step 5
See Opening a Topology Map for information on opening maps.

Creating Static Links
When dynamic links are not visible in your topology map, you can create static links. You can create a static link between network elements by selecting the two end ports of the network elements. You can create a static link between two managed network elements. To create a static topological link, you have to select the exact location of the two end ports (at both ends of the link).
The new link is validated after the two ports are selected but before the link is added. The Cisco ANA Topology module validates the following:

To create a new static link:

See Viewing Network Element Properties and Viewing Topology Link Properties for details on the element and link properties.

Opening a Topology Map
You can open a map that was previously saved. When you open the map, the network information is automatically refreshed. For example, if a network element was up the last time that the map was saved and closed, and then the network element is moved to maintenance state, the next time you open the map, the management status of the network element is updated accordingly and the network element is displayed in the maintenance state.

Link view.
Detection Type column displays whether the link is dynamic link or static link.
To open a topology map:
Step 1
The list of maps that are accessible to you is displayed in the Network Domain drawer.
Step 2
If you have added a business tag to a network element, the business tag name is displayed instead of the network element name in the topology map. See Defining Business Tags, page 6-1 to create business tags.
The following color codes are used to display the map links:
•
•
•
If there are multiple links (for example, physical and Ethernet links) between network elements, these links are represented in a single line. The A and Z ends of the links are displayed in the topology maps. The details of these links are available in the Link view. See Viewing Topology Link Properties from the Link View for details on links.
After discovering the network, if the interfaces are disconnected, the physical link is still visible between these interfaces. However, the alarm for Link Down connection is logged.
The topology map shows a different icon (a lock) for the network elements that are not within the scope of the user. See Creating and Managing Users, Passwords, and Scopes, page 14-34 for information on user access control.
To understand network elements representation, see Icon Reference, page G-1.

To find a network element in a map:
Step 1
Step 2
Step 3
You can enter either a complete or a partial NE name or IP address.
Step 4
The network element name that you have entered is highlighted in the map workspace. If your search criteria match more than one NE, you have to click OK multiple times to see all the NEs.
If the NE is inside an aggregate, the aggregate is expanded and the NE is highlighted.

Step 5
The aggregated node is displayed in the map workspace. Aggregated nodes are displayed as a single entity with the Aggregation icon. The aggregation node is appended with the alarm severity.
For example, the aggregation name SampleAggregation, appended with the alarm severity, results in the name SampleAggregation [5M+]. This indicates that the aggregation has five major severity alarms. The plus sign indicates that there are additional alarms of less severity associated with this aggregation.
See Network Element and Map Decorators, page G-2 for information on alarm severity icons.

Show Aggregation as Thumbnail
Enables you to look into an aggregation node in the map, including all of the aggregated elements. Thumbnails can also be nested. This is activated only if you select an aggregation node.
This tool displays the child map (aggregated node) in the context of the parent map. You can display the child map as the main display map by double-clicking anywhere inside the thumbnail bounding box region.
You can double-click anywhere in the map workspace to navigate to the parent map. You can also use the Go to Parent icon to navigate to the parent map.
