172 CHAPTER 5: WORKING WITH THE MAP
3Com Network Director applies intelligent filtering to ensure that an
operation applied to a subnet will apply to all items in the subnet that can
meet the requirements of the operation. This gives you a convenient way
to apply operations to a complete IP subnet, without having to manually
select individual items.
Device Groups
Device groups allow you to group related devices into a single submap in
your map. For example, you may wish to group all of the database servers
within a subnet into a single submap. This allows you to better represent
your network, and allows you to more easily apply menu selections to all
related devices simultaneously. For more information see “
Navigating
Between Submaps and the Top-Level Map” on page 184.
Grouping Devices into a Device Group
In order to create a device group, simply select the devices that you wish
to group together and select Edit
> Group Devices. The selected devices
will be replaced in the currently viewed submap by a Device Group icon
that represents a new device group. Similarly, the selected devices will be
replaced in the tree by a new branch within the currently viewed
submap’s branch that contains the selected devices. Clouds will appear in
a device group’s submap according to the rules given in “
Clouds and
Submaps” on page 168.
Device groups can only be created within a subnet or device group; they
cannot be created in the top-level map. A device group can only contain
devices that are members of that submap and cannot contain routers or
layer-3 switches.
Ungrouping Device Groups
If you no longer need a device group, you may ungroup the device group
by selecting either Edit
> Ungroup Devices from the menu bar, or the
Ungroup Devices option, in the right-click menu of the device group. This
will remove the device group from the submap and replace it with the
individual devices. In the tree this will remove the device group’s branch
Properties Launches the Properties dialog box for the selected items. See
“
Viewing Device Details” on page 229 for more information.
