Overview of network object management

Using Enterprise Manager™, you can view all of the nodes, pools, pool members, and virtual servers (collectively called network objects) for every managed device in your network without having to log on to each device individually. From the Network Objects screen, you can access the following details for each object type.

  • Current connections
  • Device name
  • Object name or IP address
  • Object state (nodes and pool members only)
  • Object status
Note: This feature is available only for Enterprise Manager version 2.1 and later. Data collection must be enabled to use this feature. You have the opportunity to enable data collection as part of the process of creating a list. However, if you upgraded to the current version of Enterprise Manager from a version prior to 1.7, you must re-license the system before you can enable data collection. Due to the processing power required to collect and store statistical information, data collection is available only for Enterprise Manager 3000 and 4000 platforms. If you have an Enterprise Manager 500 platform, see Chapter 5, Performing Operations on Multiple Network Objects, in the Enterprise Manager™ Administrator Guide version 2.0, for similar functionality.

Viewing network object details

You view information about objects associated with every managed device in your network, from one screen.
Note: You can view only the objects for which you have administrative partition rights. For information about administrative partitions, see the TMOS® Management Guide for BIG-IP® Systems.
  1. On the Main tab, expand Enterprise Management and then Network Objects. The Network Objects Custom Lists screen opens.
  2. Below the Custom Lists, click the name of the network object type (nodes, pool members, pools, or virtual servers) that you want to view. The screen displays the associated details for every object of the selected type.

Modifying node and pool member status

You can enable, disable, or force offline, node and pool members without having to log on to each device.
Note: You can modify the status of only nodes and pool members for which you have administrative partition rights. For information about administrative partitions, see the TMOS® Management Guide for BIG-IP® Systems.
  1. On the Main tab, expand Enterprise Management and then Network Objects. The Network Objects Custom Lists screen opens.
  2. Below the Custom Lists box, click Nodes or Pool Members. The screen displays the associated details for every object of the selected type.
  3. Check the select box next to the node or pool member for which you want to change the status.
  4. Click one of the buttons located at the bottom of the screen to change the object's status:
    • Enable - Allow traffic to the selected nodes or pool members.
    • Disable - Allow only persistent or active connections to the selected nodes or pool members.
    • Force Offline - Allow only active connections to the selected nodes or pool members.
    The Task List Properties screen opens, displaying the status of the task.

Overview of custom lists for network objects

A custom list is a collection of selected network objects that can span multiple devices in your network. You can create custom lists containing network objects that you frequently need to view and manage as a group.

There are two types of custom lists: static lists and dynamic lists. A static list is a fixed selection of network objects that does not change unless you remove objects from the list, or you delete the list. A dynamic list is a selection of network objects that match characteristics that you define in the list's rules. Enterprise Manager removes objects from the list when it displays an object for which characteristics have changed, and adds objects to this list when it detects new objects that match the defined rules.

Creating a custom static list

If you want to simultaneously view a collection of network objects, or change the status of certain nodes and pool members from one screen, you can create a custom static list that contains those objects. The objects you add to a custom static list remain until you delete them.
  1. On the Main tab, expand Enterprise Management and then Network Objects. The Network Objects Custom Lists screen opens.
  2. Click the Create List button. The Create a Custom List dialogue box opens.
  3. In the List Name box, type a name for the custom list.
  4. From List Type, select Static List and click OK. The screen displays the list you created (as part of the Custom Lists).
  5. Click an object type, located below Custom Lists, that you want to add to this list. The screen refreshes, displaying every instance of the selected object type for all of the managed devices in your network.
  6. Check the Select box next to the objects that you want to add to the list.
  7. Place the cursor over one of the selected items, click the left mouse button, and drag the items to the custom list you created. The screen displays the custom list with the objects you added.
  8. Repeat steps 5-7 for each object type that you want to add to the list.

Removing network objects from a custom static list

Custom static lists retain the same selected network objects until you delete or add an object, or you delete the list.
  1. On the Main tab, expand Enterprise Management and then Network Objects. The Network Objects Custom Lists screen opens.
  2. Click the arrow next to Custom Lists. The list expands to display all of the existing custom lists.
  3. Click the name of the static list you want to modify. The objects in the list display.
  4. Remove a network object from the custom static list, or delete the entire custom static list, as required.
    • To remove an object, check the Select box next to the object, and click the Remove From List button.
    • To delete the list, click the Delete List button.

Creating a custom dynamic list

You can create a custom dynamic list to contain network objects that have specific characteristics. Once you create this list, you can use it to view from one page all of the network objects that match the rules you specify, and to change the status of nodes and pool members. The objects in a custom dynamic list change when a new object matches the rule, or an existing object in the list no longer matches the rule.
  1. On the Main tab, expand Enterprise Management and then Network Objects. The Network Objects Custom Lists screen opens.
  2. Click the Create List button. The Create a Custom List dialogue box opens.
  3. In the List Name box, type a name for the custom list.
  4. From the List Type list, select Dynamic List and click OK. The Specify a rule for your dynamic list dialog box opens.
  5. In the Name or address should contain box, type all or part of an object's name or IP address.
  6. Define one or more of the following elements to prompt the Enterprise Manager to add a matching network object to this custom dynamic list.
    Use this element: To specify list parameters:
    Name or address should contain To include only devices with certain names or IP addresses, type all or part of an object's name or IP address in the box.
    Object Type To limit the list to a certain type of network objects, select a network object type from the list.
    Object Status To limit the list to network objects with a particular status, select a status from the list.
    Objects that have reached one or more thresholds To limit the list to network objects that have reached a defined threshold, check this box.
    Objects that currently have no connections To limit the list to network objects with no current connections, check this box.
  7. Click the Add Another button to specify additional rules, or click the Done button to save your changes. The list you created displays on the screen as part of the Custom Lists.
