Types of scoping

Network Manager offers several types of scoping.

You can enable the following types of scoping:

• You can include or exclude areas of your network (either subnet ranges or specific devices) in the discovery. Each configured area is referred to as a zone.
  Tip: If your subnet is sparsely populated, including individual routers is likely to result in a faster discovery than including the whole subnet.
• Zones can be specified within zones: within a given inclusion zone, you can specify devices or subnets that are not to be detected. These devices are not pinged by the Ping finder or interrogated by the discovery agents. For example, you can define an include scope zone consisting of the Class B subnet 1.2.0.0/16, and within that zone you can specify an exclude scope zone consisting of the Class C subnet 1.2.3.0/24. Finally, within the exclude scope zone you could specify an include scope zone 1.2.3.128/26.
• You can include or exclude non-IP devices, such as layer 1 optical devices, using a filter.
• You can configure a filter that determines whether a discovered device is interrogated for connectivity information.
• You can configure multicast scoping. This enables you to configure which multicast subnets to use as scopes for your multicast discovery.
