3 Device Manager

The Device Manager provides a set of tools that allow the user to manage their devices.

The Device Manager slider allows you to manage the following Oracle Communications Product Category and Network Function types:

• Devices—Add, manage, remove NFs (devices) from Oracle® Session Delivery Management Cloud (Oracle SDM Cloud), and fetch KPIs. Once you add a device, the Device Manager seamlessly provides access to the device.
• Device Groups—Device groups provide the ability to create hierarchical logical grouping of devices as per a user's customization.
• Sites—Sites represent a device's physical location.
• Software Upgrade—Manage device software upgrades.

Manage Network Functions and Devices

Network Functions (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.

Oracle Communications Service Provider Edge and Core Plug-in Product Category and Network Function Types

The following table describes the product category and NF types that are supported in each category.

To upload a Network Function (NF) certificate:

1. Click the Tools drop-down list and select Certificates.

   A pop-up window displays.

2. Browse to the NF certificate and click Upload.
   The certificate is uploaded.

   Note:

   Companies and organizations (public or private) that are not well-known and globally recognized Certificate Authorities (CA) with a global reach are unlikely to be accepted.

Add a Network Function with Devices

Use this task to add a network function (NF) with devices to the default device group or a device group that you created. Once the NF is added successfully, the Oracle® Session Delivery Management Cloud (Oracle SDM Cloud) is able to communicate with the devices in the NF. Note that when Identity and Access Management (IAM) is started on-premises, it automatically registers with the Oracle SDM Cloud, appearing in the Managed Devices table, and does not need to be manually added with the procedure below.

Pre-requisite: If you are not using the default Home group to add an NF, you must specify a group for the NF.

1. Expand the Device Manager slider, and click Devices.
2. In the Managed Devices - Group View pane, select a device, and click Add.
3. In the Select Network Function Type dialog box, select the product plugin Category from the table. Once you have selected a category, the Network Function Type drop-down list is populated with appropriate options.

   Note:

   Once you have added a NF to the Oracle SDM Cloud as a specific component type, if you go back and change the original component type from the device's CLI, the Oracle SDM Cloud will not automatically pick up the that change. From the Oracle SDM Cloud, you must remove the device from the Device Manager, ensure the new device is properly installed, and add it back to the Device Manager with the correct component type.
4. In the Network Function Type drop-down list, select from the following NF types:
   • Device—(Only available for SP Edge & Core) A NF that contains a single standalone device or device high-availability (HA) pair.
5. Click Continue.

If you select v3, authentication fields for SNMP version 3 appear. See below for more information about these fields. Note: When a device is configured to communicate using TLS over ACP, the certificate(s) must be imported to the Oracle SDM Cloud using the Tool, Certificate feature. For more information, see "Manage Transport Layer Security Certificates". When you add a device, you must specify whether to manage the device using SNMPv1, SNMPv2, or SNMPv3. The SNMP version cannot be changed for an existing device once it is added unless the device is removed and added again later.
   SNMP port field	The SNMP port number. The default SNMP port number is 161.
   SNMPv3 user name field	The SNMP version 3 user name.
   SNMPv3 authentication protocol drop-down list	Select the SNMP version 3 authentication protocol: HMAC192SHA2256 HMAC384SHA5126 NONE
   SNMPv3 authentication password field	The SNMP version 3 authentication password.
   SNMPv3 privacy protocol drop-down list	Select the SNMP version 3 privacy protocol: AES128—Advanced encryption standard (AES) encryption algorithm. NONE
   SNMPv3 privacy password field	The SNMP version 3 privacy password.
   SNMP community name field	The SNMP community is used to indicate to a device that the requests are from a trusted source. Before Oracle SDM Cloud can manage the device, Management Cloud Engine (MCE) IP address needs to be added to an active configured SNMP community on the device. This field applies only to SNMP version 1 and 2. The SNMP community must be configured on the device before adding the device to the Session Delivery Manager. Use the device CLI to configure the ip-addresses parameter found in the configure terminal, system, snmp-community element. For more information, see the device product documentation.

   Time zone drop-down list	Select the NF's time zone.

7. Click Apply.

The NF and its associated device(s) or the NF with the associated device(s) appear in the Managed Devices table.

Fetch KPIs For a Device

For devices that are managed under Device Manager and added under Configuration Manager, Oracle® Session Delivery Management Cloud (Oracle SDM Cloud) is able to fetch multi-dimensional Key Performance Indicators (KPIs) for a selected device based on the product type, platform, and software version. When the Oracle SDM Cloud successfully fetches a list of supported KPIs from a device, it displays them in the Dashboard slider menu under Device Manager, Device, <selected device>. Users can then select a KPI and Oracle SDM Cloud populates a table with all of the data associated with that KPI, including the selected device name and the KPI name.

When a user selects a KPI from the slider menu, the Oracle SDM Cloud displays a loading indicator until it receives the data. If it does not receive this KPI data from the device, it retries 5 times, with 1 second in between each try. If, after the 5th try, the Oracle SDM Cloud still does not receive the data, it displays an error message that no KPI data is available on that device. If a device is either not added under Configuration Manager or Oracle SDM Cloud cannot fetch the KPI list for a selected device, Oracle SDM Cloud displays an error message.

Note:

Oracle SDM Cloud caches KPI data fetched from the Management Cloud Engine (MCE) for 20 seconds, and continues to fetch the KPI data from the device each time the cache expires.

The Oracle SDM Cloud page displaying KPI data contains the following buttons and fields:

Refresh icon	Refreshes the KPI table contents.
Save to File button	Exports KPI information from Oracle SDM Cloud as a CSV file to the user's local machine. The exported file contains all of the KPI data, regardless if a filter was applied in the UI.
Search field	Allows a user to search for a specific column in the table. If the data in the table is filtered, the search happens across only the filtered data.
Set Columns button	Opens a dialog box displaying all the columns available for that KPI data table. Select or deselect the columns you want to view or hide and click OK.
Filter field and drop-down list (only for those KPIs that support filtering)	Optionally, a user can filter the data in the table if that KPI supports filtering. Users can either select from the drop-down list of type in text to display the closest matches.

Manage Transport Layer Security Certificates

TLS can be used by Management Cloud Engine (MCE) for communication to SBC network functions (NF) devices. You can upload entity or trusted certificates required for this communication to Oracle® Session Delivery Management Cloud (Oracle SDM Cloud), and Oracle SDM Cloud ensures that the MCE trust store is updated with this information. For information on creating a trusted certificate on the SBC, see the SBC's Security Guide for the SBC version you are running: https://docs.oracle.com/en/industries/communications/session-border-controller/index.html.

Trusted certificates use the X.509 cryptographic standard for security validation in public key infrastructure (PKI) that binds public keys with respective identities signed by a certificate authority (CA) or self-signed certificate. The X.509 standard specifies standard formats for public key certificates, certificate revocation lists, attribute certificates, and a certification path validation algorithm.

The Transport Layer Security (TLS) feature provides a Single Secure Sockets Layer (SSL) keystore for entity or trusted certificates that are used to authenticate outbound SSL and southbound interface (SBI) TLS communication to applications, product plugins, and their respective NF devices that run on MCE.

MCE communicates with devices using different protocols. For example, ACP, SNMP, SSH, and SFTP to communicate with devices. TLS communication between MCE and devices should be enabled for additional security. Refer to the specifications of your NF devices (client) to determine if a NF devices supports the SBI TLS feature.

Upload a New Certificate

From Oracle SDM Cloud, you can upload a new X.509 certificate from your system to the Oracle SDM Cloud.

1. On the homepage, select Tools, Certificates.

Boot Loader Image Repository

The Boot Loader Image Repository allows you to view, load, and delete all device boot loader images maintained by the Oracle® Session Delivery Management Cloud (Oracle SDM Cloud). The Oracle SDM Cloud supports automated device node (NF) boot loader upgrade across multiple NFs. However, before you can create an upgrade work order, you need to manually upload the boot loader image.

The Boot Loader Image Repository displays the Boot loader Image Archive table. The table displays the following information for each image:

Boot Loader Image File name	The name of the boot loader image uploaded.
Plugin	The plugin type selected.
Size (Bytes)	The boot loader image file size in bytes.
Date/Time created	The date and time when the file was stored on the Oracle SDM Cloud server.
Version	The boot loader version.
Checksum	The SHA256 checksum for the image. This value is a 64 character string.

To add a boot loader image:

1. Expand the Device Manager slider and select Software Upgrade, Boot Loader Image Repository.
   The Boot Loader Image Archive screen displays, showing all of the Boot Loader Images currently stored in the repository. This page contains the following buttons:

   • Add button- Allows you to add a new boot loader image from your local machine to the Oracle SDM Cloud server.
   • Delete button - Deletes a selected boot loader image. The Oracle SDM Cloud only allows you to delete boot loader images that are NOT associated with a work order and displays an error if a user attempts to delete such a boot loader image.
   • Refresh icon- Refreshes the Boot Loader Image Archive table.
2. Click Add.

   The Upload Boot Loader Image to the Archive dialog appears.

3. Select the Network Function Category from the Categories table (either SP Edge & Core or Enterprise Edge & Core). Click Browse and browse to your locally saved copy of the boot loader image.
4. Click Upload.
