Manage Network Functions and Devices

As of Oracle Communications Session Element Manager Release 9.0, the previous device nodes (used in OCSEM 7.x) that maintained the standalone or HA pair devices were replaced with the concept of a Network Function (NF). NFs are a network architecture concept used to describe entire classes of network node functions into building blocks that may connect, or chain together, to create communication services as defined by the GS NFV-MAN 001 - ETSI. In this context, a NF can be composed of one-to-many Edge devices. For example, a SBCbased NF can be composed of two SBC instances running as a HA pair.

Add a Network Function with Devices

When preparing to use Device Manager, you set up device groups and add Network Functions (NF) to the groups. After you successfully add a NF, the system can communicate with the associated device and you can launch the login page for the device by way of the Session Element Manager.

  • Optional—If you do not want to use the default device group, named Home, add the device group that you want. See "Configure Device Groups for Network Function."
  • Configure SNMP community on each device that you plan to add to the device to Device Manager. See the device documentation.

Use the following procedure to add a Network Function (NF) to a managed device group. You can add more NFs by repeating the procedure.

Note:

The table in the following procedure displays all possible configuration attributes, but the system displays only the set that corresponds to the selections that you make in this configuration.
  1. Expand the Device Manager slider, and click Devices.
  2. In the Managed Devices - Group View pane, select a device group, and click Add.
  3. In the Select Network Function Type dialog, do the following:
    1. Select a Category from the drop-down list.
    2. Select a Network Function from the drop-down list.
  4. Click Continue.
  5. In the Add Network Function: Device dialog, complete the following fields:
  6. Click Apply.
    The system adds the NF to the specified managed device group and displays a green icon by the name of the device in the Managed Devices - Group View table upon successful addition. The Managed Devices - Group View table displays IP address or FQDN depending on the details added by the user in the Device Manager.

Manage Network Functions

Once you have added one or more NFs with a group hierarchy, you can manage them as described in the following sections.

Launch a Managed Device Login Page

You can use Oracle Communications Session Element Manager as a single source from which to access and manage multiple products. When you select a device and click Launch, the system communicates to the device and displays the login page.

  1. Expand the Device Manager slider, and click Devices.
  2. On the Managed Devices - Group View page, select the device that you want to login to.
  3. Click Launch.
    The system displays the login page for the selected device. You can access the web GUI using the IP address or FQDN. When you launch a managed device using FQDN, the FQDN to IP mapping is looked up in the DNS. If the FQDN to IP mapping is present in the DNS, the web GUI can be accessed using FQDN. The web GUI access using IP address searches either the /etc/hosts or the DNS.

Edit a Network Function with Devices

  1. Expand the Device Manager slider and click Devices.
  2. In the Managed Devices pane, expand the appropriate group folder hierarchy, select the NF folder and click Edit.
  3. In the Edit device group dialog box, change the appropriate parameters:
  4. Click Apply.
    A success dialog box displays that the NF was changed.

Move a Network Function to Another Group

You cannot move the NF if it is locked unless you are the owner of the lock or an administrator overrides the lock. An error message appears in both situations. See Override a Locked Network Function section for more information about unlocking an NF.

  1. Expand the Device Manager slider and click Devices.
  2. In the Managed Devices page, expand the appropriate group folder hierarchy, select the NF folder and click Admin, Move.
  3. In the Move Device dialog box, click the device group folder to which you want to move the NF and click OK.
  4. In the Success dialog box, click OK.
    The NF moves to the new folder location that you specified.

Lock or Unlock a Network Function

You can lock or unlock an NF and its device(s) with the appropriate administrator permissions.

Note:

Other users are prevented from rebooting, updating or modifying the configuration or route sets for an NF when you lock it. Only users with granted override lock permissions can override your lock or the NF must be unlocked by you.
  1. Expand the Device Manager slider and click Devices.
  2. In the Managed Devices pane, click the NF you want to lock and click Admin, Lock if it is unlocked or Admin, Unlock if it is locked.
  3. In the confirmation dialog box, click Yes.
    A padlock icon appears next to the IP address of the NF folder and its device(s). This padlock is removed if the NF is unlocked.

Override a Locked Network Function

Note:

You must have the appropriate privileges assigned by your administrator to override a lock set on an NF by another user.
  1. Expand the Device Manager slider and click Devices.
  2. In the Managed Devices pane, click the NF folder icon you want to override lock and click Admin.
  3. From the Admin pop-up menu, select Override lock.
  4. In the Confirm dialog box, click Yes.
  5. In the Managed Devices pane, click Refresh.
    The padlock icon no longer appears next to the NF folder and IP address(es) of the device(s).

Override a Locked Device

Note:

You must have the appropriate privileges assigned by your administrator to override a lock set on a device by another user.

    The padlock icon no longer appears next to the device.

View Network Function Information

Use the following sections to view and manage Oracle session delivery product NF information, which includes its devices and the way detailed and summary NF information is displayed for its device node(s).

View Device States and Columns

You can monitor a variety of information for devices by viewing the state of their colored, round icons, and by using the column information presented for each device.

Expand the Device Manager slider and click Devices. The system displays a device group hierarchy showing the group, subgroup, and the network function (NF) that contains the devices.

The following states of a device in the Managed Devices table indicate if it can be reached by Oracle Communications Session Element Manager:

  • Green—The Oracle Communications Session Element Manager can reach the device and retrieve information about the device through SNMP.
  • Red—The Oracle Communications Session Element Manager cannot currently reach the device (or cannot contact both devices in an HA device pair).

The following columns appear in the Managed Devices table:
