How do I check network health in the Network Map?

Map view

The Network Map is a graphical display of your network equipment and its interconnections. If the view is configured with a background map layer, equipment can be positioned on the map, based on its actual physical location. NEs are grouped into geographical regions and zones. The map can be zoomed out to view equipment from a broad perspective, or zoomed in to view only a handful of NEs.

Note: The background map layer is configured by an NSP administrator in the NSP system settings.

Administrative users can view subnets and links to subnets as objects on the Network Map. Non-administrative users whose access rights are defined through UAC cannot view subnets and links to subnets because the Network Map is intended to display networking equipment. Subnets are not actual equipment.

The Network Map does not support LLDP links with endpoints with the destination MAC address set to Nearest Customer.

Alarm and status information in the Network Map is automatically refreshed from the network every 30 seconds. You can update the map display manually by clicking Refresh. The Refresh command can take significant time to complete on large networks. Use it only if there have been changes to the NSP common map layout (for example, recently-added NEs, links) and you want them to appear in the Network Map view, or if the map data is stale (in which case you are prompted to refresh the map).

If a region titled NEs Without a Region appears on the map, it is an auto-created region containing NEs that exist in the Network but have not been grouped under a specific region. Your administrator must place the NEs in a region.

Map object clustering for small networks

In small NSP deployments of fewer than 2000 NEs and 3000 links, where no common map layout is configured, map objects can be clustered automatically based on their proximity, if the Cluster by Proximity option is enabled in the Map Palette. If the object limits are exceeded, The Network Map displays an error message, indicating that the administrator must configure a common map layout, dividing NEs into regions.

Common map layout

The Network Map layout can be derived from the NSP common map layout, as configured by an NSP administrator under Map Layouts and Groups. With this arrangement, map objects are clustered into regions and zones, as configured by the administrator.

Network monitoring workflow

Use the following dashlet features to expand on your network health investigation:

• Search for an object in the map; see How do I search for an object in the map?.

• Examine an NE in an external GUI; see How do I view information about an object in the map?.

• View network layers; see How do I view multiple network layers in the Network Map?.
