Enable Windows Active Directory access

If you intend to use Windows Active Directory, or AD, for single sign-on client access, you must configure LDAP remote authentication for AD; otherwise, go to Step 73.

Open the following file as a reference for use in subsequent steps:

/opt/nsp/os/install/examples/config.yml

Note: Consider the following.

• The NFM-P does not assign a default user group to users of a remote authentication source that you define for Windows AD; the authentication source must provide the user group attributes.

• Windows AD supports the following LDAP server types for remote authentication:

  AD—The user group of an AD user is derived from the group_base_dn attribute in the server configuration; group search filters are not supported.

  AUTHENTICATED—The server configuration must include bind credentials; group search filters are supported. After NFM-P initialization, you add the AD server bind credentials to the NSP password vault using the NSP Session Manager RESTCONF API.

Locate the section that begins with the following lines:

#   ldap:

#     enabled: true

#     servers:

#       - type: AUTHENTICATED/AD/ANONYMOUS

#         url: ldaps://ldap.example.com:636

#         security: SSL/STARTTLS/NONE

Open the following file using a plain-text editor such as vi:

/opt/nsp/os/install/config.json

Locate the section that begins with the following line:

"sso": {

The section has one subsection for each type of SSO access.

Note: You can enable multiple remote authentication methods such as LDAP and RADIUS in the config.json file, or by using the NFM-P GUI. Using the GUI also allows you to specify the order in which the methods are tried during login attempts; however, no ordering is applied to multiple methods enabled in the config.json file.

In the sso section, create an ldap subsection as shown below using the parameter names from the ldap section of config.yml and the required values for your configuration.

The following example shows the LDAP configuration for two AD servers:

    "ldap": {

      "enabled": true,

      "servers": [

        {

          "type": "auth_type",

          "url": "ldaps://server1:port",

          "server1_parameter_1": "value",

          "server1_parameter_2": "value",

          .

          .

          "server1_parameter_n": "value",

          },

        {

          "type": "auth_type",

          "url": "ldaps://server2:port",

          "server2_parameter_1": "value",

          "server2_parameter_2": "value",

          .

          .

          "server2_parameter_n": "value",

          },

      }]

    }

where auth_type is AD or AUTHENTICATED

Configure WS-NOC integration

If the NFM-P is integrated with a WS-NOC system, open the following file with a plain-text editor such as vi; otherwise, go to Step 83.

/opt/nsp/os/install/examples/config.json

See WS-NOC and NSP integration for comprehensive information about NFM-P integration with the WS-NOC.

Copy the following section:

  "nfmt": {

    "primary_ip": "",

    "standby_ip": "",

    "username": "",

    "password": "",

    "cert_provided": false

  },

Close the file.

Open the following file with a plain-text editor such as vi:

/opt/nsp/os/install/config.json

Paste in the copied section.

Configure the required parameters to enable the WS-NOC integration:

• primary_ip—the primary WS-NOC server IP address

• standby_ip—the standby WS-NOC server IP address

• username—the username required for WS-NOC access

• password—the password required for WS-NOC access

• cert_provided—whether a TLS certificate is used

Save and close the file.

# chown -R nsp:nsp /opt/nsp/nfmp/server/nms/nodeSoftware ↵

Integrate NFM-P and NSP cluster

If you are upgrading an NFM-P system that is not currently integrated with an NSP cluster, perform procedure To add an independent NFM-P to an existing NSP deployment.

Note: Performing the procedure also starts the main server.

Start main server

CAUTION Service Disruption

An NFM-P system upgrade is not complete until each main server performs crucial post-upgrade tasks during initialization.

Before you attempt an operation that requires a server shutdown, you must ensure that each main server is completely initialized, or the operation fails.

Note: You cannot start a main server unless the main server configuration includes a current and valid license. You can use samconfig to specify the license file, or import a license, as described in the NSP System Administrator Guide.

Start the main server, if it is not started.

1. Enter the following to switch to the nsp user:

   # su - nsp ↵

2. Enter the following:

   bash$ cd /opt/nsp/nfmp/server/nms/bin ↵

3. Enter the following:

   bash$ ./nmsserver.bash start ↵

4. Enter the following:

   bash$ ./nmsserver.bash appserver_status ↵

   The server status is displayed; the server is fully initialized if the status is the following:

   Application Server process is running.  See nms_status for more detail.

   If the server is not fully initialized, wait five minutes and then repeat this step. Do not perform the next step until the server is fully initialized.

If you have enabled Windows Active Directory access using the AUTHENTICATED type of LDAP server, use the NSP Session Manager RESTCONF API to add the LDAP server bind credentials; see the Network Developer Portal for information.

Specify the memory requirement for GUI clients based on the type of network that the NFM-P is to manage.

1. Enter the following:

   bash$ ./nmsdeploytool.bash clientmem -option ↵

   where option is one of the following:

   • m—medium, for management of limited-scale network

   • l—large, for a network of 15 000 or more NEs

2. Record the setting, which is not preserved through an upgrade, for future use.

3. Enter the following to commit the configuration change:

   bash$ ./nmsdeploytool.bash deploy ↵

Close the console window.

Check post-upgrade disk space

If you are performing a trial upgrade on a lab system in advance of a live upgrade, you must check the available capacity of the disk partitions on each component against the values recorded in Step 1.

Perform the following steps on each of the following stations:

• main server

• auxiliary server

• main database

1. Log in to the station as the root user.

2. Open a console window.

3. Enter the following:

   # df -kh ↵

   The usage information for each partition is displayed.

4. Record the information for each NFM-P partition; see the tables in Chapter 2, NSP disk setup and partitioning for the partition names and required capacities.

5. Compare the partition values with the values recorded in Step 1.

6. If the disk usage on an NFM-P partition approaches 80% or has increased substantially, you may need to add disk capacity before you attempt the upgrade on a live system. Contact technical support for assistance.

Perform NSP analytics server migration to NSP cluster

If the system includes one or more NSP analytics servers, move the analytics-server functions to the NSP cluster, as described in NSP analytics server migration from Release 22.6 or earlier.

Install or upgrade single-user GUI clients

As required, install or upgrade additional single-user GUI clients; see the following for information:

• NFM-P single-user GUI client installation

• NFM-P single-user GUI client upgrade from Release 22.6 or earlier

Install or upgrade client delegate servers

As required, install or upgrade client delegate servers; see the following for information:

• NFM-P client delegate server installation

• NFM-P client delegate server upgrade from Release 22.6 or earlier

Stop PKI server

If no other components are to be deployed, stop the PKI server by entering Ctrl+C in the console window.

Restore TLS version and cipher support configuration

An NFM-P system upgrade does not preserve your changes to the system support for specific TLS versions and ciphers.

If the system had customized TLS settings before the upgrade, see the NSP System Administrator Guide for information about how to restore the TLS version and cipher support settings.

Note: TLS 1.0 and 1.1 are disabled by default after an upgrade. If either version is enabled before an NFM-P system upgrade and required after the upgrade, you must re-enable the version support after the upgrade.

Configure and enable firewalls

If you intend to use any firewalls between the NFM-P components, and the firewalls are disabled, configure and enable each firewall.

Perform one of the following.

1. Configure each external firewall to allow the required traffic using the port assignments in the NSP Planning Guide, and enable the firewall.

2. Configure and enable firewalld on each component station, as required.

   1. Use an NFM-P template to create the firewalld rules for the component, as described in the NSP Planning Guide.

   2. Log in to the station as the root user.

   3. Open a console window.

   4. Enter the following:

      # systemctl enable firewalld ↵

   5. Enter the following:

      # systemctl start firewalld ↵

   6. Close the console window.
