Enabling and Disabling Next Gen Services

To use Next Gen Services, you must first enable it on the MX Series router. This topic describes how to enable Next Gen Services, how to disable Next Gen Services, and how to determine whether Next Gen Services is enabled or disabled on your system.

Loading the Software Images on Next-Generation Routing Engines

The Next-Gen Services MX-SPC3 services card can exhibit inconsistent behavior when the vmhost image is installed on the Next-Generation Routing Engines listed:

  1. RE-S-X6-64G-BB (NG-RE)
  2. RE-S-X6-64G-UB (NG-RE)
  3. RE-S-X6-64G-S (NG-RE)
  4. RE-S-X6-64G-R (NG-RE)
  5. RE-S-X6-128G-S-BB (NG-RE)
  6. RE-S-X6-128G-S-S (NG-RE)
  7. RE-S-X6-128G-S-R (NG-RE)

This behavior can result in you encountering one of the following:

  • The MX-SPC3 card remains in Present state and does not come online

  • The MX-SPC3 comes online successfully with different a software image (either a previously installed image or the pre-loaded image from manufacturing)

To work around this problem, you must install the jpfe-spc3* package manually on the NG-RE. To install this package manually, follow one of these procedures, depending on whether or not you have enabled Next Gen Services (unified-services) mode:

If unified-services are enabled:

  1. Download the jpfe-spc3* package that matches the Junos vmhost version you plan to load on the RE from: Downloads
  2. Note: Unified services must be enabled on all routing engines on the device.
     Load the selected vmhost* image on the RE.
  3. After the RE boots, copy the jpfe-spc3* package to the /var/tmp directory
  4. Load the jpfe-spc3* package. Modify the command to match your specific jpfe-spc3* version:

If unified-services are disabled:

  1. Download the jpfe-spc3* package that matches the Junos vmhost version you plan to load on the RE from: Downloads

  2. Load the desired vmhost* image on the RE

  3. After the RE boots, enable unified-services mode:

  4. Copy package jpfe-spc3* package to the /var/tmp directory.

  5. Load the jpfe-spc3* package. Modify the command to match your specific jpfe-spc3* version:

Note:

When MX-SPC3 card is installed on an MX chassis, misconfig alarm is reported with the reason as FPC in unsupported mode. This alarm might be seen when the unified services is disabled.

Enabling Next Gen Services on an MX Series Router

There are specific steps you’ll need to take if you’re migrating your services from MS-MPC cards to the MX-SPC3 services cards. The Next Gen Services CLI differs from these legacy services.

The following procedure is a general procedure for enabling and disabling Next Gen Services.

Before you do anything, you’ll need to back up your configuration.

For more details on the differences between the configuration of the MX-SPC3 services card and legacy services cards, see Configuration Differences Between Adaptive Services and Next Gen Services on the MX-SPC3 and plan your migration appropriately.

You can run Next Gen Services on the MX240, MX480 and MX960 using the MX-SPC3 services card. To use Next Gen Services on the MX Series, you must first enable Next Gen Services:

  1. Delete any router configuration that is for services. This includes configuration under the [edit services] hierarchy, configuration for services interfaces, and any configuration that refers to services interfaces.
  2. Enable Next Gen Services.
  3. When the following message appears, enter yes.
  4. Reboot the MX Series chassis.

You can also enable the Next Gen Services on a Guest network function (GNF), by using the CLI request system enable unified-services at the GNF level. For more information, see Next Gen Services on Junos node slicing.

Disabling Next Gen Services on an MX Series Router
