About 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 2.2, 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, click Enterprise Management > Network Objects. The Network Objects Custom Lists screen opens.
  2. Left of the screen, below the Advanced Search box under Custom Lists, click the name of the network object type (nodes, pool members, pools, or virtual servers) that you want to view. The screen refreshes to display 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, click Enterprise Management > Network Objects. The Network Objects Custom Lists screen opens.
  2. Left of the screen, below the Advanced Search box, click Nodes or Pool Members. The screen displays a list and associated details for every object of the selected type.
  3. Select the check box next to the node or pool member for which you want to change the status.
  4. Below the list, click one of the buttons to change the object's status:
    • Enable - Allows traffic to the selected nodes or pool members.
    • Disable - Allows only persistent or active connections to the selected nodes or pool members.
    • Force Offline - Allows only active connections to the selected nodes or pool members.
    The Task List Properties screen opens, displaying the status of the task.

About custom lists for network objects

A custom list is a collection of selected network objects. The objects in a custom list can span multiple devices in your network.

There are two types of custom network object 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 network object 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, click Enterprise Management > Network Objects. The Network Objects Custom Lists screen opens.
  2. Click the Create List button. The Create a Custom List dialog box opens.
  3. In the List Name field, type a name for the custom list.
  4. From the List Type list, select Static List and click OK. The screen displays the custom static list that you created (as part of the Custom Lists).
  5. Left of the screen, below the Advanced Search box under Custom Lists, click the name of the network object type (nodes, pool members, pools, or virtual servers) 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. Select the check box next to the objects that you want to add to the custom static list list.
  7. Place the cursor over one of the selected items, left-click and hold the mouse button, and drag the items to the custom static list that you created. The screen refreshes to display the custom static 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, click Enterprise Management > 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 custom static list that you want to modify. The objects in the custom static list display.
  4. Select the check box next to the network object that you want to remove from the custom static list, and click the Remove From List button. The screen refreshes to display the custom static list without the objects you removed.

Creating a custom dynamic network object list

You can create a custom dynamic list to contain network objects that have specific characteristics. After 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, click Enterprise Management > Network Objects. The Network Objects Custom Lists screen opens.
  2. Click the Create List button. The Create a Custom List dialog box opens.
  3. In the List Name field, 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 field, type all or part of an object's name or IP address.
  6. Specify 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: If you want the system to:
    Object Type Limit the list to a certain type of network objects, select a network object type from the list
    Object Status Limit the list to network objects with a particular status, select a status from the list
    Objects that have reached one or more thresholds Limit the list to network objects that have reached a defined threshold, select this check box
    Objects that currently have no connections Limit the list to network objects with no current connections, select this check 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.

Deleting a custom network object list

Custom network object lists remain active until you delete them.
  1. On the Main tab, click Enterprise Management > 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 network object lists.
  3. Click the name of the static list you want to delete.
  4. Select the check box next to the custom network object list that you want to delete and click Confirm. The screen refreshes and the list displays without the custom network object list that you deleted.
