Configuring Device Groups
This section includes the following topics:
Creating a Device Group
You can create a device group and add one or more devices to it.
There is only one default group. All other groups are custom device groups.
DETAILED STEPS
Step 1 From the Feature Selector pane, choose
DCNM Server Administration > Device Groups
.
The Summary pane lists custom device groups, if any. The default group does not appear.
The Details pane shows the group name, description, and a list of devices in the group.
Step 2 From the menu bar, choose
Actions > Create Device Group
.
A blank row appears in the Summary table.
Step 3 In the blank row, under Device Group Name, enter a name for the group.
Step 4 (Optional) Under Description, enter a useful description of the group.
Step 5 In the Details pane, expand the Membership Details section, if necessary.
Step 6 To add devices to the group, do the following:
a. Right-click below the column names in the Membership Details section and choose
Add Device
.
The Device Selection dialog box appears.
b. (Optional) Use the Select Search Criteria drop-down list to filter the devices shown in the Available Devices list. You can filter devices in one of the following ways:
– All devices—Shows every discovered device.
– Device type—Shows only discovered devices of the type that you choose, such as Cisco Nexus 7000 Series switches.
– Unsupported devices—Shows discovered devices that DCNM-LAN cannot manage and monitor.
– Connected devices—Shows discovered devices connected within the number of hops that you specify to the seed device that you specify by IP address.
– Subnet devices—Shows discovered devices whose IP addresses are within the subnet that you specify by the IP address of the subnet and the subnet mask.
c. Move one or more devices from the Available Devices List to the Selected Devices list.
To move one device, click the device and then click
Add
.
To move more than one device, press and hold
Ctrl
, click each device, and then click
Add
.
d. Click
OK
.
Step 7 From the menu bar, choose
File > Deploy
to save the device group configuration.
The new group is available in the topology map.
Each device that you added to the new device group is removed from its previous group. If a preexisting, nondefault device group became empty because you moved all its devices to the new device group, DCNM-LAN automatically deletes the empty device group.
Adding Devices to a Group
You can add devices to an existing device group.
All devices belong to one and only one group. Devices that are not members of a custom device group automatically belong to the default device group.
Adding a device to a group automatically removes the device from the group that previously contained the device.
BEFORE YOU BEGIN
Ensure that the device group that you want to add the devices to exists.
DETAILED STEPS
Step 1 From the Feature Selector pane, choose
DCNM Server Administration > Device Groups
.
The Summary pane lists custom device groups. The default group does not appear.
The Details pane shows the group name, description, and a list of devices in the group.
Step 2 Click the device group to which you want to add one or more devices.
Step 3 In the Details pane, expand the Membership Details section, if necessary.
Step 4 To add devices to the group, do the following:
a. Right-click below the column names in the Membership Details section and choose
Add Device
.

– Subnet devices—Shows discovered devices whose IP addresses are within the subnet that you specify by the IP address of the subnet and the subnet mask.
c. Move one or more devices from the Available Devices List to the Selected Devices list.
To move one device, click the device and then click
Add
.
To move more than one device, press and hold
Ctrl
, click each device, and then click
Add
.
d. Click
OK
.
Step 5 From the menu bar, choose
File > Deploy
to save the device group configuration.
On the topology map, the device group will include the devices that you added to it.
Each device that you added to the device group is removed from its previous group. If a preexisting, nondefault device group became empty because you moved all its devices to the new device group, DCNM-LAN automatically deletes the empty device group.
Removing Devices from a Group
You can remove devices from a custom device group. All devices that you remove from a custom group are added to the default device group.
Tip If you want to move devices from one group to another, add them to the other group. DCNM-LAN automatically removes devices from one group when you add them to another group.
DETAILED STEPS
Step 1 From the Feature Selector pane, choose
DCNM Server Administration > Device Groups
.
The Summary pane lists custom device groups. The default group does not appear.
The Details pane shows the group name, description, and a list of devices in the group.
Step 2 Click the device group from which you want to remove one or more devices.
Step 3 In the Details pane, expand the Membership Details section, if necessary.
Step 4 In the Membership Details section, select the devices that you want to delete.
To select a single device, click the device.
To select more than one device, press and hold
Ctrl
, and then click each device.
Step 5 Right-click on one of the selected devices and choose
Delete
.
DCNM-LAN removes the selected devices from the device group.
Step 6 From the menu bar, choose
File > Deploy
to save the device group configuration.
On the topology map, the default device group will include the devices that you deleted from the custom device group.
Each device that you deleted from the custom device group is added to the default device group. If the custom device group became empty because you removed all its devices, DCNM-LAN automatically deletes the empty device group.
Deleting a Device Group
You can delete a custom device group.
Devices that belong to a custom device group that you delete automatically become members of the default device group.
Tip If you add all the devices of a custom device group to another custom device group, DCNM-LAN automatically deletes the empty device group.
DETAILED STEPS
Step 1 From the Feature Selector pane, choose
DCNM Server Administration > Device Groups
.
The Summary pane lists custom device groups. The default group does not appear.
The Details pane shows the group name, description, and a list of devices in the group.
Step 2 Click the device group that you want to delete.
Step 3 From the menu bar, choose
Actions > Delete Device Group
.
DCNM-LAN removes the device group from the Summary pane. The devices that were in the deleted device group are now members of the default device group.
Step 4 From the menu bar, choose
File > Deploy
to save the device group configuration.
On the topology map, the default device group will include the devices that were in the deleted device group.
