Understanding Network Element States
Based on the results of inventory collection, network elements are moved to the appropriate states in ANA.
When you use the network element selector, you can see that the network elements that have been added to ANA are grouped based on the network element state and UMDF. See Using the Device Selector, page 1-15 for information on UMDF.
Table 3-1 lists the network element states in ANA.
Table 3-1 Network Element States
State
|
Description
|
Managed
|
ANA has completed investigation of the network element, and the VNE is operational. Most elements go to this state after being added to ANA. Some components may not be supported (and thus not modeled properly), but all other aspects are fully functional.
In this state, the network element has been successfully contacted by ANA, or the network element has contacted ANA at least once (polling, successful job completion, Syslog receipt, and so on). This state indicates that this is a real element in the network.
This state does not guarantee that there was a successful inventory and configuration collection.
ANA supports the processing and display of faults generated as a result of receiving SNMP traps. The faults are processed and displayed from a network element only when it is in this state.
When the VNE is stopped, the managed elements are moved to Unmanaged state. When the VNE is moved to maintenance state, the managed elements are also moved to maintenance state.
|
|
Maintenance
|
ANA is managing the element, but the element is not being polled.
The VNE is capable of switching to this state automatically. This switch is performed when the network element's CPU usage reaches a certain configured level. This behavior prevents the VNE from using too much of the network element's resources.
The traps and syslog are not processed by the VNE.
|
Unmanaged
|
ANA is not currently managing the network element; the VNE is nonoperational, but all element information is retained.
When a VNE is stopped or not reachable, the element is moved to this state.
|
Unsupported
|
ANA could not identify the appropriate network element components because the model or version is not supported by ANA.
|
Changing the Network Element State from the Inventory Perspective
You can change the state of a network element in the following ways:
•From the Inventory perspective, select Configuration > Set Device State.
•From the Administration perspective, use the ANA Servers drawer (see Changing a VNE's State, page 2-28).
You can change any of the network element states to one of the following:
•Manage Device—When you want the inventory collection to be polled at a regular interval. The VNE can also process the traps and syslogs that are sent by the network element.
•Unmanage Device—When you decide not to manage this element. That means you want to stop the inventory collection on this network element. The network element historical data are retained in the database.
•Mainentance—When you want to perform maintenace activity, such as replacing modules or cards or upgrading to a newer software version. You can change the state to maintenance to avoid or ignore any alarms that might be raised during the network element maintenance activity.
Roles Required to Change a Network Element State
Table 3-2 lists the roles that are required to change a network element state. For more information on roles, see Creating and Managing Users and Scopes, page 14-27.

To change the network element state from the Inventory perspective:
Step 1 Go to the Inventory perspective.
Step 2 Select Configuration > Set Device State and choose one of the following:
•Manage Device. The Set Device State to Managed dialog box appears.
•Unmanage Device. The Set Device State to Unmanaged dialog box appears.
•Maintenance. The Set Device State to Maintenance dialog box appears.
Step 3 Select the network elements and click OK.
Viewing the Network Element Inventory
This section describes how to view the physical and logical inventories of a selected network element.
ANA maintains a continuous, real-time discovery of all the physical and logical entities of the network inventory and the relationships among them. It automatically reflects every addition, deletion, and modification that occurs in the network in its distributed system inventory.
The physical and logical inventory collection depends on the polling interval that you have specified while adding the network element. See Managing Polling Groups, page 14-4, for information on defining the polling interval.
The collection happens only for the network elements that are in managed state. You can view the physical and logical inventory for the network elements that are moved from managed state to maintenance state.
See the following to view the network element properties:
• Viewing Network Element Properties
• Viewing Physical Inventory Properties
• Viewing Logical Inventory Properties
Viewing Network Elements
The Device drawer is available from the Object tab of the Inventory Perspective. This tab lists all of the network elements that are available in the ANA server. You can view all of the network elements based on either the UMDF grouping or the ANA network element states.
See Understanding Network Element States for information on UMDF and ANA network element states.
You can perform the following tasks by selecting a network element in the Device drawer:
•Viewing physical and logical inventory information
•Viewing network element properties
•Viewing tickets for the network element
•Changing the network element state
•Opening Command Builder
•Opening Soft Property Builder
•Opening Config Archive
•Opening Network Element Image Management
•Attaching a business tag
Viewing Network Element Properties
To view the network element properties:
Step 1 Select a network element in the Device drawer.
Step 2 Right-click and choose Properties.
Or
Double-click the network element.
The network element properties are displayed in the workspace.
If the Properties view is enabled, the network element properties are displayed there. If you have disabled the Properties view, you can enable it using Window > Show View > Properties.
The following network element properties are displayed:

Viewing Physical Inventory Properties
The physical inventory reflects the physical components of the managed network element. The Physical Inventory tab displays a hierarchical (tree) view of the physical inventory, which might include chassis, modules, shelves, slots, subslots, ports, and so on for the selected network element in the Device drawer.
The Physical inventory is continuously updated for both status and configuration polling groups. The addition of a new card, the removal of a card, or any change to the network element is reflected by the VNE and updated instantly.
You can view the physical inventory properties by double-clicking any of the network element attributes in the Physical Inventory view.
