Use Map Views

This topic includes the following sections:

• Understand Maps
• Navigate Maps
• Refresh Node Status on a Map
• Control Tool Tips Information on a Map
• Access Maps Provided by NNMi

A map view is a powerful way to display information about your network. In a map view, nodes, interfaces, IP address, and subnets are represented as symbols on the map. The lines between the nodes and interfaces represent the connection or relationship between these objects.

For each symbol, a background shape indicates the type of device, such as router or switch. See About Map Symbols. The color of this background shape indicates the current health of the device. See About Status Colors for more information about map color values.

On the maps, a foreground image is placed over the background shape. The foreground image identifies the make and model of the network device.

You access map views from the Topology Maps and Troubleshooting workspaces. You can also open maps from table views using the Actions menu. See Access Maps Provided by NNMi and Use Actions to Perform Tasks for more information.

You can also right-click any object in a table or map view to access the items available within the Actions menu.

Depending on the type of map you are viewing, NNMi uses additional conventions to depict other kinds of objects on the map:

Node Group Map Objects

Layer 2 Neighbor View Map Objects

Layer 3 Neighbor View Map Objects

Path View Map Objects

Some NNMi users can delete nodes and other objects from the NNMi database (depending on the assigned NNMi Role). Any node that has been deleted appears as a transparent icon to all NNMi users until their map is refreshed using the  Refresh icon. After Refresh, the deleted node is removed from the map. NNMi does not automatically refresh the connectivity or set of nodes in a map view, except on the Initial Discovery Progress and Network Overview maps.

You can perform the following operations in a map view:

• Access More Information About an Object (Forms and Analysis Pane)
• Refresh a View
• Change the Map Layout
• Adjust the Zoom Factor
• Pan Around the Map
• Set the Location of the Overview Pane
• Select Highlight Options for VLAN Maps
• Find a VLAN for Highlighting VLAN Maps
• Refresh Node Status on a Map
• Control Tool Tips Information on a Map

If you use the Mozilla Firefox browser and have any timeout issues; for example, being prompted to click Continue before a map appears, see Configure Mozilla Firefox Timeout Interval.

About Status Colors

The color of the background shape of each map symbol conveys the most recent health status of that Node. The color of each connection icon (the line) conveys the most recent health of communication between the two Nodes (determined by evaluating the status of each Interface or IP address involved). At the end of each connection line, the color of each interface icon (small square) or IP address icon (small hexagon) also conveys its most recent health status. For example:

NNMi calculates the appropriate Status for objects:

• Status Color for Objects
• Status Color for Aggregator Objects ()
• Status Color for Network Connections

NNMi's Causal Engine collects the data for calculating each object's Status value. Using the State information collected by the State Poller as well as this additional information, the Causal Engine calculates the Status of each Node, Interface, and SNMP agent.

• State = This value is provided by the NNMi State Poller and is always up to date for each object.
• Status = This value can run behind by the amount of time listed for Delay Processing Input in the System Information dialog's Causal Engine tab. See System Information: Causal Engine tab and Verify Current Status of a Device.

Status Color for Objects

NNMi displays the status color within background shapes on map objects that represent Nodes (devices) within your network.

The following table describes the meaning of each potential status color.

Background Shape's Status Color

Color	Meaning	Description
	Unknown	Indicates the object is unreachable and cannot be polled.
	Normal	Indicates there are no known problems related to the associated object.
	Warning	Indicates there might be a problem related to the associated object.
	Minor	Indicates NNMi detected problems related to the associated object that require further investigation.
	Major	Indicates NNMi detected problems related to the associated object to be resolved before they become critical.
	Critical	Indicates NNMi detected problems related to the associated object that require immediate attention.
	Disabled	Indicates the object is administratively disabled.
	No Status	Indicates one of the following: NNMi's current configuration excludes this object from monitoring. The Status is not calculated because the object is set to Not Managed/Out Of Service/Scheduled Node Outage. The object has just been added to the NNMi database and the Causal Engine has not yet calculated its health status.

Status Color for Aggregator Objects (NNMi Advanced)

Link Aggregation protocols enable network administrators to configure a set of interfaces on a switch to function as one. This technique of combining multiple interfaces increases bandwidth, the speed at which data travels, and provides redundancy.

On a Layer 2 map, a thick line with a superimposed ellipse represents a Link AggregationProtocols used on Switches to configure multiple Interfaces (Aggregation Member Interfaces) to function as if they were one (an Aggregator Interface). When two Aggregator Interfaces establish a connection, that connection is an Aggregator Layer 2 Connection. The Aggregator Layer 2 Connection appears on Layer 2 Neighbor View maps as a thick line with an Interface icon at each end (representing the Aggregator Interface). or Split Link AggregationLink Aggregation with more than two endpoints. Some vendors refer to this as Multi-Chassis Link Aggregation, SLAG, MLAG, or MC-LAG. (group of multiple Layer 2 Connections that are functioning as one). The icon representing an Interface at either end of the thick line is an Aggregator Interface (a logical interface comprised of many physical interfaces that are functioning as one).

Two endpoints:

Three endpoints:

More than three endpoints:

See Layer 2 Map Objects for more information.

The following table describes the meaning of each potential status color for an Aggregator Interface.

Aggregator Interface Status Color

Color	Status	Meaning
	Unknown	Indicates all of the participating Aggregation Member Interfaces are unreachable and cannot be polled.
	Normal	Indicates all of the participating Aggregation Member Interfaces have a Status of Normal.
	Minor	Indicates at least one (but not all) of the participating Aggregation Member Interfaces has a Status of Critical.
	Major	WENDY: DOES Major (or Warning) APPLY TO AGGREGATE INTERFACES? Indicates NNMi detected problems related to the associated object to be resolved before they become critical.
	Critical	Indicates all of the participating Aggregation Member Interfaces have a Status of Critical.
	Disabled	Indicates all of the participating Aggregation Member Interfaces are administratively disabled.
	No Status	Indicates one of the following: NNMi's current configuration excludes all of the participating Aggregation Member Interfaces from monitoring, so the Status is not calculated. For example, the entire device or the Aggregator Interface is set to Not Managed/Out Of Service/Scheduled Node Outage. All of the participating Aggregation Member Interfaces have just been added to the NNMi database and the Causal Engine has not yet calculated their health status.

Status Color for Network Connections

Map lines indicate network connections. The color of these lines indicates current status. There are three types of lines on NNMi maps that indicate network communication paths:

• Single connection lines from one interface to another (network Layer 2 communications) or from one address to another (network Layer 3 communications).

• Multiconnection lines save space on complex NNMi maps. The NNMi administrator configures how many single connections dynamically condense into one thick line.

• Aggregate connection lines are thick lines with a superimposed ellipse representing a group of multiple connections that are functioning as one.

Single Connections

The following table describes the meaning of each potential status color for a single network connection.

Special icons within the line indicate additional information.

Network Connections Status Color

Color	Meaning	Description
	Unknown	Indicates that due to other network problems, the status of one interface cannot be determined at this time.
	Normal	Indicates both interfaces in the connection are responding.
	Warning	Indicates there might be a problem with either interface.
	Minor	Indicates the interface on one end is not responding. The interface on the other end is responding.
	Critical	Indicates neither interface or IP address is responding.
	Disabled	Indicates one or both interfaces are administratively disabled.
	No Status	Indicates one of the following: NNMi's current configuration excludes one or both interfaces from monitoring. The Status is not calculated because the interface is set to Not Managed/Out Of Service. The interface has just been added to the NNMi database and the Causal Engine has not yet calculated its health status.

About Map Symbols

Map symbols convey the following information:

• The background shape and foreground image of map icons indicate the type of device being depicted.

• The lines between devices indicated network connections. Special icons within those lines indicate additional information.

For more information: See Also

Background and Foreground

Map symbols represent nodes or node groups. Each map symbol that represents a single node has a background shape and a superimposed foreground image (default images are shown in the table below). Custom foreground images might represent specific vendors and models.

The NNMi administrator can customize the NNMi foreground image for each Device Profile. Therefore, you might see foreground images that are not described in the following table. Contact your NNMi administrator if you have questions about any additional foreground shapes.

The color of the background shape indicates the most recent health status of the device (see Status Color for Objects and Status Color for Aggregator Objects (NNMi Advanced)).

Special Connections

The icons in the following table provide valuable information about certain connection lines between devices within your network. There are various types of communication channels within networks. The lines between map objects provide valuable information about both the type of connection and current health of that connection. See Status Color for Network Connections for more information.

When you click a connection line, NNMi displays the port number at each end of the selected connection:

• Press p to toggle the port number off or on.
• Press n to toggle the device names off or on.

Node Group Map Objects

 See "Help for Operators" for more information about Node Group maps.

Node Group maps show members of a Node Group (as defined by the NNMi administrator). Each Node Group Map shows either Layer 2 or Layer 3 information.

The map displays the status of each member, connection, and Child Node Group. To provide context for your environment, the NNMi administrator might also add a background image (for example, a map of North America).

NNMi can enlarge the map symbol of any node associated with a Key IncidentIncidents with both: (1) Severity = other than Normal. (2) Correlation Nature = equal to Root Cause, Service Impact, Stream Correlation, Rate Stream Correlation, Info, or None.. Use the   Indicate Key Incidents button in the map view toolbar (see Using the View Toolbars: Node Group Map Toolbar Icons):

(on) = When the this Node Group map opens, NNMi enlarges any objects on a Node Group map that are Source Objects for a Key IncidentIncidents with both: (1) Severity = other than Normal. (2) Correlation Nature = equal to Root Cause, Service Impact, Stream Correlation, Rate Stream Correlation, Info, or None.. (For example, when viewing the Node Group map, NNMi enlarges any node on a Node Group map that has an open root cause incident associated with it.)

(off) = When the this Node Group map opens, NNMi does not indicate the objects on a Node Group map that are Source Objects for a Key IncidentIncidents with both: (1) Severity = other than Normal. (2) Correlation Nature = equal to Root Cause, Service Impact, Stream Correlation, Rate Stream Correlation, Info, or None..

To view the associated incident for the node, double-click the node symbol. In the Node form, select the Incidents tab.

Because these maps are based on Node Groups rather than connectivity, some nodes might not have any connections on the map.

A hexagon (as shown below) indicates a Child Node Group:

A gray halo around a map icon indicates a device that is one-hop outside of the displayed Node Group (connected to a Node Group member, but not itself a member). Not all one-hop neighbors are displayed. Your NNMi administrator must configure the Node Group map to show one-hop neighbors if those neighbors are members of the particular Node Group used as the filter.

See Views Available in NNMi for information about the Node Group maps that NNMi provides.

Layer 2 Map Objects

Layer 2 maps show a map view of a selected device and any connected devices within a specified number of hops from the selected device. This is useful for understanding the switch connectivity between devices. See "Help for Operators" for more information.

During discovery, NNMi reads the Forwarding Database (FDB) tables from Ethernet switches within a network to help NNMi determine communication paths between network devices. NNMi searches these FDB tables for information about discovered nodes. When an NNMi management server finds FDB references to duplicate MAC addressesThe Media Access Control address (hardware address or physical address) that the factory burns into a network adapter or device with built-in networking capability. A MAC address has six pairs of hexadecimal digits, separated by colons or dashes. For example 02:1F:33:16:BC:55:

• If two or more discovered nodes contain an interface associated with the same Media Access Control (MAC) address within the same Tenant or with one of those nodes in Default Tenant and one in any other Tenant, NNMi disregards the communication paths reported for those duplicate MAC addresses in the FDB. This might result in missing connections on NNMi maps in network areas that include those duplicate MAC addresses.

  (NNMi Advanced - Global Network Management feature) If two NNMi management servers discover nodes that contain an interface associated with the same Media Access Control (MAC) address, the Global NNMi management server's maps could be missing connections that are visible on the Regional NNMi management server's maps.

• If a single node contains multiple interfaces that have the same MAC address, NNMi gathers all communication path information for those interfaces and displays that information on NNMi maps.

Forwarding Database (FDB) information can cause NNMi to establish wrong Layer 2 Connections in the following cases:

• When the FDB is configured as cache and contains obsolete data.
• In network environments with hardware from a variety of vendors, when each vendor generates different and sometimes conflicting FDB data.

Optional: NNMi administrators can configure Spiral Discovery to ignore the FDB data from one Node Group when calculating Layer 2 Connections (the FDB data is still included in other calculations).

For example, in Layer 2 Neighbor View maps, interfaces are indicated by little squares around the background shape of the parent node. Each interface also has a status color.  Green indicates the interface is working properly. Red indicates the interface is down.

Connection Lines	Meaning of Connection Line
	Thin lines between devices indicate communication channels between the two devices (connections). The lines also show status color indicating the current health of that connection. See Status Color for Objects.
	A thick line that does not have any interface icon at both ends is a multiconnectionA multiconnection is a thick line on a map view between two Node icons, two Node Group icons, or between a Node icon and a Node Group icon (with no Interface icon or IP Address icon at either end of the line). This thick line represents a set of multiple connections that have been combined to preserve space and simplify the map. Your NNMi administrator specifies the number of connections that must exist before NNMi condenses them into a multiconnection line (User Interface Configuration's Multiconnection Threshold attribute). Double-click the thick line to convert it into the original set of connections with Interface icons or IP Address icons at either end of the lines.. Double-click the thick line to expand the group of individual links.

The Aggregator Layer 2 Connection appears on Layer 2 Neighbor View maps as a thick line with an Interface icon at each end (representing the Aggregator Interface). protocols are in use. These protocols enable network administrators to configure a set of interfaces on a switch as one Aggregator Interface, creating an Aggregator Layer 2 Connection to another device using multiple interfaces in parallel to increase bandwidth, increase the speed at which data travels, and increase redundancy. Double-click the thick line (the Aggregator Layer 2 Connection) to open the Layer 2 Connection form for more information. NNMi calculates the status of the thick line (Aggregator Layer 2 Connection) based on the status of the entire group of Aggregation Member Layer 2 Connections. See Status Color for Aggregator Objects () for more information. When the link aggregation has more than two endpoints, NNMi depicts the link as a Split Link AggregationLink Aggregation with more than two endpoints. Some vendors refer to this as Multi-Chassis Link Aggregation, SLAG, MLAG, or MC-LAG. (SLAG) group of links.

The delegations might be static or dynamic, depending on the manufacture's implementation. The type of virtual machines being generated depends on the manufacturer's implementation.:

See "Help for Operators" for more information about Layer 2 maps.

Layer 3 Map Objects

Layer 3 maps show a selected device and its connected devices within a specified number of hops from the selected device. This view is useful for understanding the router connectivity between devices.

For example, in Layer 3 Neighbor View maps, addresses connected to neighbors within the same subnet are indicated by hexagons around the background shape of the parent node. Each address has a status color. Green indicates the address is working properly. Red indicates the address is not responding. The line between devices indicates the subnet. The subnet does not have any status:

(NNMi Advanced) IPv6 subnets are indicated by this symbol:

See "Help for Operators" for more information about Layer 3 Neighbor View maps.

Path View Map Objects

Path View maps show an active network path between a source and destination end point.

The main objects in the displayed path in a Path View map are routers and switches.

Do not specify a switch as a Source or Destination node in Path View maps. To view connectivity between switches, use the Layer 2 Neighbor View.

When NNMi cannot determine the nodes within a portion of the path, it uses a Cloud object as shown in the example below:

If a black arrow or empty black circle appears at the end of the connection in Path View maps, NNMi was not able to determine a status value because the connection or interface is not in the NNMi database. Click here for more information.

Reasons a connection or interface are not stored in the NNMi database, include the following:

• NNMi is unable to collect information about a node in the path because it is a non-SNMP node.
• A node in the path is not managed by NNMi.
• The discovery information for a node is not up-to-date (for example, interface information is missing).
  

Path View maps also show objects included in Layer 2 Neighbor View maps and Layer 3 Neighbor View maps. See "Help for Operators" for more information.

(NNMi Advanced) Path View works only with IPv4 addresses. The NNMi Advanced IPv6 address values are not valid choices for Path View. Any devices in your network that are configured with IPv6 addresses cannot be displayed on Path View maps.

(NNMi Advanced) If your network administrator configures NNMi to gather data from Router Redundancy Groups that have more than one Active router, NNMi selects one Active router for the path. To indicate there is more than one possible path, NNMi connects any additional routers to the Active router as shown in the example below:

(NNMi Advanced), plus Route Analytics Management System (RAMS) for MPLS WAN) If your network administrator configures NNMi to gather data from Route Analytics Management System (RAMS), the Path View can show multiple OSPFOpen Shortest Path First Protocol Equal Cost paths through a Layer 3 cloud as shown in the example below:

If you are an NNMi administrator, see RAMS MPLS WAN Configuration (NNMi Advanced) for information about configuring RAMS.

Refresh Node Status on a Map

In map views, you can refresh the node status on a map while maintaining the layout of the nodes. This feature enables you to quickly refresh a view when you are only concerned with status updates for one or more nodes on your map.

NNMi automatically refreshes node status on a map every 60 seconds. The refresh counter begins after the completion of the last status refresh.

If a map is taking longer than expected to refresh, the maximum number of nodes that are displayed on a map might be set too high. The NNMi administrator can set this value. See "Help for Administrators" for more information.

You can refresh the node status manually.

To refresh only the node status:

Click the  Refresh Status icon in the toolbar to manually refresh node status on your map view.

The last update time is changed and the status of each node is refreshed on the map. Nodes are not added, deleted, or rearranged. Connectivity is not recalculated.

Some NNMi users can delete nodes and other objects from the NNMi database (depending on the assigned NNMi Role). Any node that has been deleted appears as a transparent icon to all NNMi users until their map is refreshed using the  Refresh icon. After Refresh, the deleted node is removed from the map. NNMi does not automatically refresh the connectivity or set of nodes in a map view, except on the Initial Discovery Progress and Network Overview maps.

Control Tool Tips Information on a Map

When you place the mouse cursor over an object on a map, NNMi displays Tool Tips information for the current object. Tool Tips information is a subset of the information contained in the object's form.

Each time you open a map, the  Tool Tips button is enabled.

To disable Tool Tips popups, click the  Tool Tips button. NNMi closes any open Tool Tip dialog boxes.

Access Maps Provided by NNMi

You can access maps in the following ways:

• From table views using the Actions menu
• From the  Topology Maps and  Troubleshooting workspaces
