To switch between topological mode and geographical mode

The topological map in ENA provides a visual representation of the network connectivity in the selected View. If you amend a map by adding a device, for example, then you will also amend the View.

Topological maps display the following information:

• subViews and devices in the View.
• connections between subViews and devices, and between devices.
• device and connection status. These statuses are automatically updated by ENA.
• technology used when disccovering these connections.

To add a Map dashlet to a custom dashboard:

Please see this article for help and information on the initial process of adding or editing a Map dashlet.

To set map preferences:

You can specify universal map preferences via the Preferences form.

Features of the topological map:

What is shown on the map

The map is populated by icons representing the subViews within the View, as well as devices within the View. These are represented by icons. The type of icon displayed depends on the object they represent and the Map user preference you have set.

Icon	Name
	BladeCenter
	cloud
	DeviceEx
	firewall
	generic device
	hub
	hypervisor
	managed host
	router
	server
	switch
	View
	virtual machine
	vpn gateway
	wireless controller
	wireless router

Incidents

If there are any incidents in the subView or on the device, then a small diamond is displayed to the top right of the object icon. Note, this is a separate metric to the object status indicator described below.

• The diamond will be colored according to the highest-severity open incident for that View or device with a severity level higher than Information (e.g., if there are any critical incidents in the View, the marker will be colored red). The number in the diamond corresponds to the severity level. The incident severity levels are as follows:
   

  UI Display Severity	Internal Severity	Color Code	Description
  1	2	green	information/cleared
  2	4	yellow	minor
  3	6	amber	major
  4	8	orange	severe
  5	10	red	critical

Status and utilization

Depending on the Map Overlay that you have chosen, you can immediately see status or utilization information about the View or device. Utilization is relative to the thresholds set on the View or device. ENA indicates the status of a View or device on a map by displaying a color-coded disc as the background of the object. Note, this is a separate metric to the incident severity indicator described above.

• For a View, the disc is colored according to the most critical status or utilization of an object within that View.
• For a device, the disc is colored according to the status or utilization of the device.  In your user Preferences, you can specify whether or not you want devices that are in a normal state (i.e., they have no known issues) to be displayed with a green disc (if not, then devices in a normal state will simply have no background).

• Status colors:
  
  

  Object Color	Object Status	Description
  	Down	device or port is being polled and is down.
  	Degraded	device or port is being polled and is degraded.
  	Unknown	device or port is being polled, but ENA could not determine the status, for example because: -device unreachable but not root cause. -port data unavailable because the device is down.
  	OK	device or port is being polled and is OK.
  none	Administrative Down	ENA identifies an object as administrative down when: -for a device, polling of the device is disabled. -it is a custom device and is therefore not polled. -for a port, it is set to administrative down. -a link does not have an associated port, e.g. when using a physical connection.

• Utilization colors:
  
  

  Object Color	Link Color	Utilization Status	(Object Status)	Description
  		Critical	(Ok/Degraded)	device or port is responding and has crossed its critical utilization threshold.
  		High	(Ok/Degraded)	device or port is responding and has crossed its high utilization threshold.
  		Low	(Ok/Degraded)	device or port is responding and has crossed its low utilization threshold.
  		Unknown	(Ok/Degraded)	device or port utilization could not be determined.
  		Any	(Unknown)	device or port utilization could not be determined.
  		Any	(Down)	device or port utilization could not be determined.
  		Normal	(OK/Degraded)	device or port is responding and has not any utilization thresholds.
  none		Any	(Administrative Down)	ENA identifies an object as administrative down when: -for a device, polling of the device is disabled. -it is a custom device and is therefore not polled. -for a port, it is set to administrative down. -a link does not have an associated port, e.g. when using a physical connection rather than to an interface on the device.
  none		Any	(System Uninitialized)	device or port has not yet been fully discovered by the system.
  none		Null (no data returned)	(Ok/Degraded)	device or port is OK, but utilization data cannot be retrieved. Possible causes might include: -the device might be a hypervisor or a managed host. -the map's Links are displaying only routing links, and the routing protocols do not refer to ports.

To change a map's overlay:

The overlay applies to devices on a map, and the links between devices and between Views. By default, the map overlay is set to 'Status'.

1. Click Overlay: Status. The Map Overlay form will slide in on the right.
2. Click the field and select Status or Utilization.
3. Click Done in the top right of the form to save and exit, or Cancel to cancel.

To specify custom utilization bands:

From ENA v18.0 P06 upwards, you can specify your own custom utilization bands. The existing Utilization map overlay displays utilization relative to thresholds that you set, but with custom utilization bands you can specify link color based on overall utilization.

To specify custom utilization bands:

1. In the Map Overlay form, select Utilization.
2. The Use Custom Util Bands field will appear below. Switch it on.
3. By default, a single custom util band appears for 0-100% utilization, colored red. Either click + Add Util Band or click on an existing band to edit its value parameters and change its color.
   
   
   
   
4. Edit or curate new bands as you wish by entering the lowest value % of the band and its color, and then click Done to save the band.
   
   
   
   
   
   
5. The bands will appear on the Map Overlay form. Click Done to save your changes, otherwise click Cancel. Note, if you switch off Use Custom Util Bands or change Map Overlay to Status, your saved custom utilization bands will still be available when you turn custom utilization bands back on.
   
   

To highlight a specific View, service or network path on a map:

If you want to highlight a specific View, or the View in which a service is located, or a network path on the map, you can specify this via the Highlight button at the top of the dashlet. By default, the map highlight is set to 'None'. The highlight mode 

1. Click Highlight: None. The Map Highlight form will slide in on the right.
2. Click the Highlight field and select what you want to highlight on the map:
   
   
   
   
   • None - no highlights.
   • View - select View, and then from the View field below, select the View you want to highlight.
   • Service - select Service, and then below select the View which your desired service is in, and then below select your desired service.

• Layer 2: SONMP - SynOptics Network Management Protocol.
• Layer 2: Spanning Tree.
• Layer 3: IP Peers - IP peering.
• Layer 3: Trace Route - Trace Route ping state.
• Other: Custom Connection - displays any user defined physical connections in the map. You can create a custom connection from the map via the right-click context menu.
• Other: Host Detection - host detection.
• Other: IPv6 ND - IPv6 ND is available in ENA through the IPv6 module. When it is activated through configure, ENA discovers port IPv6 addresses on IPv6 managed devices. You can then use the IPv6 ND to show links between IPv6 devices using neighbor discovery.
• Other: VM Detection - VM detection.
• Routing: BGP - Border Gateway Protocol.
• Routing: EIGRP - Enhanced Interior Gateway Routing Protocol.
• Routing: IS-IS - Intermediate System to Intermediate System.
• Routing: OSPF - Open Shortest Path First.

To view details of links between managed objects:

You can drill down into the links between managed objects for further information.

1. Navigate to the Map for your chosen View/subView.
2. Double click on the connection you want to look at, or right click on it and click Show Details on the menu that appears.
   
   
   
   
3. From ENA v18.0 P06 upwards, the Link Details window will appear (if you are using an earlier version of ENA, a form will slide in on the right). The Link Details window lists all connections between the two connected managed objects.
   
   
   
   The status and direction of each connection is displayed, along with the SubViews/components (and their parent devices) that are connected. You can click on each subView, component or device to open the Summary dashboard for the selected managed object.
4. You can filter the list with free text via the Filter Table field in the top right:
   
   
   
   Or by clicking the Overflow Menu and clicking Edit Filter, which opens the Filter Columns form:
   
   
   
   
   
   
5. You can also remove all filters by clicking Reset Filter via the Overflow Menu.
   
   

To change the layout of objects on a map:

1. Navigate to the Map dashboard for your selected subview.
2. On the map itself, click and hold down the mouse button on the subview/device you want to move. A purple highlight will appear on the object, so that you can see exactly which object it is you have selected. Drag the object to where you want to move it. The connections from this object will move with it in real time, showing you how the map will look.
3. To move two or more objects at the same time and in the same arrangement, hold CTRL and select the objects you want to move. Drag any of the highlighted objects to where you want them to be moved.

To customize inline and hover-over tooltip labels on a map:

You can add customizable labels on the Topological Map that can display any attribute that is not a time-series metric. You can display up to 3 fields of information on the map itself (under the device/metric), and up to 10 fields of information on a tooltip that is displayed when hovering over the object/device.

You can specify whether to display the following:

• both inline and hover-over tooltip labels.
• just inline labels.
• just hover-over tooltip labels.
• none.

In the below example, you can see an example of an inline label (red arrow) and hover-over tooltip label (yellow arrow):

To specify/edit the labels you want to see on a Topological Map:

3. This opens the Add Custom Device form on the right. Enter the name of the device and click Done, otherwise click Cancel. 

To save changes to a map: 

In ENA, all map definitions are stored on the Entuity server and then drawn on the web browser that you are using. If you adjust the map layout (e.g. by dragging an object or View from one position to another) and then click Save, the map definition is updated and saved.

Because more than one user can access the same View and therefore the same map, it is possible that another use will make a change to and save a map whilst you are viewing it. When this happens, the map that you are viewing will automatically refresh and update.

The following list shows map changes that can be saved:

• changes to the positional coordinates of nodes on the map, i.e. where objects appear on a map. Changes can be caused by repositioning objects on the map, adding objects to the map, and removing objects from the map.
• changes to the map overlay.
• changes to the display of links.
• changes to the background image of the map.

Note, zooming or panning within a map is not saved to the map definition.

To export a map to Visio: 

ENA supports integration with Visio 2003, Visio 2007, Vision 2010 and Visio 2013 through the .vdx XML drawing file format. The layout of the network in the export file is the same as that in the currently displayed ENA topological map. The exported map uses a predetermined set of network icons.

1. Navigate to the topological map that you want to export.
2. Click the Map dashlet Overflow Menu.
3. From the menu, click Export to Visio. ENA will generate a .vdx file, and the filename will be the name of the View shown by the map. E.g., a topological map for the View called "UK" will be exported to Visio with the filename UK.vdx.

To switch between topological mode and geographical mode:

Geographical mode is the other type of map available in ENA. Please see this section for further help and information on Geographical maps.

1. Navigate to your desired View, and access the Map dashboard (or a custom dashboard containing a Map dashlet).
2. Click the Mode toggle at the top of the Map dashlet (which will be showing Topological Mode, depending on your preferences), and select Geographical Mode. The dashlet will then change to the Google Maps satellite map display.
3. To switch back to the topological mode, click the Mode toggle (which will be showing Geographical Mode) and click Topological Mode.
