HP Netsight manual Creating and Modifying a Subnet Entry

Discovering Nodes

Figure 3-20. The Subnets Window

The Subnets window displays entries for all manually-defined (via this window or the Discover application) subnets; if you have manually added a node to the central node database, a subnet entry will be listed for that node’s subnet as well.

Each subnet entry will be listed with its name, description, the network and subnet portions of its IP Address, its subnet mask, and count of the nodes in the central node database that reside on that subnet. A subnet’s name, description, and address are all defined using the Subnet Properties window. Automatically-created subnet entries are named with their IP address by default; no default description is provided.

Note that the Nodes value displayed here does not have the same meaning as the Nodes

TIP value displayed in the Subnet Properties window (Figure 3-6, page 3-8); that value indicates the maximum number of nodes that could be included in a subnet defined by the given subnet mask, and does not indicate how many nodes on a specific subnet have been added to the central node database.

Creating and Modifying a Subnet Entry

To create a new subnet entry or modify an existing one:

1.To define a new subnet, click New; or click the right mouse button anywhere in the Subnets window, and select New from the resulting menu.

To modify an existing subnet, highlight the subnet entry that you wish to change, and click Properties; or click the right mouse button on the subnet entry that you wish to modify, and select Properties from the resulting menu.

The Subnet Properties window (Figure 3-7, page 3-10) opens.
