1 About This Document

This document describes the configuration that is a prerequisite for vMRF to process traffic. The configuration tasks in this document are performed after the vMRF VNF has been deployed using the relevant deployment instructions.

This document is written for vMRF operator personnel who are responsible for the deployment of vMRF. The vMRF operator is assumed to be a cloud service consumer on a cloud service.

2 vMRF Initial Configuration Tasks

Initial configuration includes the following tasks:

Steps

3 Configure vMRF Application

Initial vMRF application configuration consists of configuring user plane networks and H.248 signaling links.

The following methods are available, as shown in Figure 1:

Figure 1   Options for Initial Configuration of vMRF Application

3.1 Importing Configuration Data from NETCONF Template

An example initial configuration file is part of the vMRF software delivery package, with the name example_config.tar.gz.

The tar.gz file contains the following:

  • An XML file that contains MO configuration values. The example tar.gz file contains an example XML file with the name config.xml. You must edit the XML file with values that match your environment, as described in the procedure below. As an optional service, Ericsson can provide a file that is already edited to match your environment.

  • Node credentials: You must add the node credentials to the tar.gz file, as described in the procedure below.

  • Trusted certificates: You must add the trusted certificates to the tar.gz file, as described in the procedure below.

  • manifest.yaml: The file contains configuration metadata for the import and the contents of /usr/share/image/package_build_data for troubleshooting.

Note:

You must manage the content of the tar.gz file using a Python script that is also delivered in the vMRF software delivery package. To run the script, you need Python installed on a Linux computer.

3.2 Create and Import Configuration Data

This procedure describes how to create and import the initial configuration data.

Steps

  1. Extract the XML file from the tar file for editing using the vmrs_config_update.py script:
    vmrs_config_update.py -c example_config.tar.gz -gxf config.xml
  2. Edit the XML file with specific values for your environment, as described in the relevant deployment instruction. For a list of MOs and attributes to configure, see Initial Configuration Data for the vMRF Application.
    Note: The XML document is case-sensitive, pay attention when editing MO names and attributes.
  3. Pack the XML file back into the tar.gz file, using the vmrs_config_update.py script:
    vmrs_config_update.py -c example_config.tar.gz -sxf config.xml
  4. Add the node credentials and trusted certificates to the tar file, and set the LDAP password using the vmrs_config_update.py script:
    vmrs_config_update.py -c example_config.tar.gz -anc key.pem cert.pem –atc <trusted certificate>.pem ldap <password>
  5. Open an SSH connection to the O&M IP address of the vMRF VNF using the following command:
    ssh <user ID>@<O&M IP address>

    Emergency user credentials are needed to perform this step.

  6. Copy the modified tar.gz file to the VNF using, for example, the scp command:
    scp example_config.tar.gz <user ID>@<O&M IP address>:/home/<user ID>

    The configuration file is copied from the current directory to the /home/<user ID> folder in the file system of the vMRF VNF.

  7. Run the following command:
    /opt/mrf_director/mrf_import_conf.py /home/<user ID>/example_config.tar.gz

    The configuration data is imported and vMRF connects to the user plane and signaling networks.

3.2.1 Additional Security Configuration

Configure security as described in vMRF Security Management. Skip the installing node credentials and trusted certificates configuration steps, as they were already performed during the configuration data import procedure.

3.3 Manual Configuration

Manual configuration means configuring each MO and MO attribute using the ECLI or a NETCONF client.

Manual configuration requires emergency user credentials for logging in to the vMRF VNF until security configuration is completed.

If ECLI is used, do the following:

Steps

  1. Connect to the O&M IP address of the vMRF VNF by issuing the following command:
    ssh <user ID>@<O&M IP address>
  2. Start a session by issuing the cliss command

If a NETCONF client is used, connect to the O&M IP address of the vMRF VNF using the client.

    3.3.1 Configure Security

    For information on security configuration, refer to vMRF Security Management.

    3.3.2 Configure vMRF User Plane

    Do the following:

    Steps

    1. In the MOM, navigate to ManagedElement=1,MediaResourceFunction=1. Check that the mediaIpVersion attribute is configured correctly. mediaIpVersion is visible only in configure mode.
      Note: The mediaIpVersion attribute is only visible in configure mode.

      See Table 1 for the details.

    3.3.3 Configure vMRF Signaling

    Do the following:

    Steps

    1. In the MOM, navigate to ManagedElement=1,MediaResourceFunction=1,MrfH248Control=1, and create a MrfH248Interface MO for the H.248 connection.

      In the created MrfH248Interface MO, configure the following attributes:

      • mrfH248InterfaceId
      • remoteIpAddress
      • remotePortNumber
    2. To activate the H.248 link towards the MTAS, set the administrative state of the given MrfH248Interface MO to UNLOCKED.

      See Table 2 for the details.

    3.3.4 Create a Basic Announcement

    This procedure describes how to create a BasicAnnouncement MO, that represents a single audio announcement file.

    Prerequisites

    • An Ericsson Command-Line Interface (ECLI) session in Exec mode is open.

    • The announcement files are available on the announcement storage server or in the local storage.

    Steps

    1. In the MOM, navigate to ManagedElement=1,MediaResourceFunction=1,Announcements=1,BasicAnnouncements=1 and create a BasicAnnouncement MO for each audio announcement file.
    2. For each created BasicAnnouncement MO, define values for the following attributes:

      • announcementId

        An identity for the basic announcement. The combination of the announcementId and languageCode attributes form a unique identity for the basic announcement.

      • basicAnnouncementId

        The value component of the RDN.

      • fileName

        The name of the announcement file.

      • filePath

        The relative file path to the directory where the announcement file is stored. The value of this attribute is relative to the announcement_storage_server_path attribute in the deployment template. In case of local storage the value of the attribute is relative to /cluster/storage/announcements.

        Example: basic/en-GB/

      • languageCode

        Language code of the basic announcement. The combination of the announcementId and languageCode attributes form a unique identity for the basic announcement.

        Language code has the format of an RFC 5646 language tag.

        Example: en-GB

      The following attributes are optional:

      • duration

        The amount of time the announcement is to be played in milliseconds. If the specified duration is greater than the overall length of the announcement, the announcement is repeated until the duration is elapsed. The playing time is also dependent on the value of the iteration attribute. The selected playing time is always the shortest possible alternative.

      • iteration

        The number of times the announcement is repeated when played to the user.

      • userLabel

        Label for free use.

    4 Configure SNMP for Fault Management

    The Simple Network Management Protocol (SNMP) provides alarm notifications.

    The used SNMP version must be consistent with the SNMP targets used in the network fault management system. The recommended SNMP version is SNMPv3.

    Do the following:

    Steps

    1. Create SNMP targets using one of the following instructions:
      Note: To prevent modification of the management information base (MIB) files through SNMP, the isMibWritable attribute of the SNMP target MOs is recommended to be set to false during the creation of the target.
    2. SNMP views can be created to restrict read/write access to SNMP MIBs. It is recommended to grant SNMP access only to the ERICSSON-ALARM-MIB, that is needed for fault management purposes. This can be done by creating an SNMP view with readOids attribute set to 1.3.6.1.4.1.193.183 using the instruction Create SNMP View.

    For the default SNMP settings, refer to the Snmp MO in the MOM.

    For more information on fault management, refer to Fault Management.

      5 Configure the networkManagedElementId Attribute

      This procedure describes how to configure the networkManagedElementId attribute of the ManagedElement MO. The attribute changes the RDN visible in, for example, NETCONF transactions and PM files. This task is required for the OSS-RC interworking.

      Prerequisites

      An Ericsson Command-Line Interface (ECLI) session in Exec mode is in progress.

      Steps

      1. In the MOM, navigate to the ManagedElement MO and enter configure mode:
        >ManagedElement=1
        (ManagedElement=1)>configure
      2. Modify the value of the networkManagedElementId attribute:
        (config-ManagedElement=1)>networkManagedElementId=<value>
        Note: The value must be unique within the network namespace.
      3. Commit the changes:
        (config-ManagedElement=1)>commit

        The job is completed.
