Configuring Host and Subnet Groups

A host or subnet group is a list of IP addresses (in dotted decimal format) or of host names that will be resolved by the systems host's database or networks table. A subnet group also contains a subnet mask.

Figure 5-3 Host and Subnet Group Window

The Group List in the left hand column displays all the currently configured Host and Subnet groups. Configurable parameters are:

• Group name

  Assign a new group name when you create the group.

• Group Type

  This can be either Host or Subnet

• Address List

  The list of addresses that compose the group.

• Subnet mask

  The subnet mask. This is only required for a subnet group. This must be expressed in IP dotted notation, or as a name that can be resolved by the system's host table.

To add an address to a host or subnet group:

1. From the Group List, select the group you want to add an address to.

   The addresses currently contained in the group are displayed in the adjacent address list panel.

2. In the Address List panel, double-click in the empty line below the last address entry.

   The text editing mode starts, indicated by a cursor in the empty line.

3. Type the address you want to include in the group.

   The address can be specified as a hostname or IP address.

4. Click Apply.

   The address is added to the group.
