1-Port VDSL2 Annex A Mini-Physical Interface Module (SRX-MP-1VDSL2-R)

 

1-Port VDSL2 Annex A Mini-Physical Interface Module (SRX-MP-1VDSL2-R) Overview

Very-high-bit-rate digital subscriber line (VDSL) technology is part of the xDSL family of modem technologies, which provide faster data transmission over a single flat untwisted or twisted pair of copper wires. The 1-Port VDSL2 Annex A Mini-PIM carries the Ethernet backplane. When the Mini-PIM is plugged into the chassis, the Mini-PIM connects to one of the ports of the baseboard switch. The 1-Port VDSL2 Annex A Mini-PIM on the SRX Series Services Gateway provides ADSL backward compatibility.

The 1-Port VDSL2 Annex A Mini-PIM is compatible with the ITU-T G.993.2 (VDSL2) standard.

Figure 1 shows the 1-Port VDSL2 Annex A (SRX-MP-1VDSL2-R) Mini-PIM.

1-Port VDSL2 Annex A Mini-Physical Interface Module (SRX-MP-1VDSL2-R) Basic Configuration

To enable the 1-Port VDSL2 Annex A Mini-Physical Interface Module (Mini-PIM) installed on the services gateway, you must configure the basic settings for the PIM. You can perform the configuration tasks for this using either the J-Web interface or the CLI.

Using the J-Web Interface

To perform basic configuration for the 1-Port VDSL2 (Annex A) Mini-Physical Interface Module (Mini-PIM) and to configure network interfaces for the services gateway using the J-Web interface:

  1. In the J-Web interface, select Configure>Interfaces.

    The Interfaces page displays and lists the network interfaces present on the services gateway, along with configuration information (if configured).

  2. Select the interface name (pt-1/0/0) and click Add > Logical Interfaces. Enter the details and click OK. To use the port on the Mini-PIM, assign an IP address to the port and assign it to a security zone, other than the Null zone. If there are no security zones listed, proceed to the next step to add a security zone.
  3. Add a security zone to the interface:
    1. Select Configure>Security>Zones/Screens.
    2. Add or select a security zone other than Null; for example, Trust. Assign the interface to the zone.
    3. For Host Inbound Traffic-Zone, set the following:

      • System Services=Allow All

      • Protocols=Allow All

    4. Click OK to save changes, and select Commit>Commit to apply the configuration and other pending changes.
  4. To use the port on the Mini-PIM, you must also set security policies. Select the following settings:
    1. Select Configure>Security>Security Policy
    2. Select Global Options > Policy Options.
    3. Set Policy Action: Default Policy Action=Permit-All
    4. Click OK to save changes, and select Commit>Commit to apply the configuration and other pending changes (if any).

For more information, in the J-Web interface, select Configure>Interfaces and click Help.

Using the CLI

To perform basic configuration of the 1-Port VDSL2 Annex A Mini-PIM and to configure network interfaces for the services gateway with the CLI:

  1. Verify that the 1-Port VDSL2 interface is installed on the device:

    show chassis hardware

  2. Verify the status of the interface:

    show interfaces terse

  3. Assign the port an IP address:

    set interfaces pt-1/0/0 unit 0 family inet address interface address/destination prefix

  4. Add or select a security zone; for example, Zone1:

    set security zones security-zone trust interfaces pt-1/0/0.0 host-inbound-traffic system-services all

  5. Add or select security zones for host inbound traffic options protocols:

    set security zones security-zone trust interfaces pt-1/0/0.0 host-inbound-traffic protocols all

  6. Set security policies:

    set security policies default-policy permit-all

Upgrading the Firmware on the VDSL2 Mini-PIM

To upgrade the firmware on the VDSL2 Mini-PIM using the CLI:

  1. Identify the currently installed firmware (jfirmware) version.

    user@host > show system firmware

    Note

    Ensure that you upgrade the firmware on the Mini-PIM to the latest version.

    The Current version field in the output displays the firmware version that is currently installed on the Mini-PIM. If there is a newer version of the firmware at https://www.juniper.net/support/downloads/?p=junos-srx#sw, then proceed to the next step to download the latest firmware.

  2. Download the appropriate firmware version from https://www.juniper.net/support/downloads/?p=junos-srx#sw.

    user@host > request system software add /var/tmp/jfirmware-<version>-signed.tgz

    Note

    Ensure that the Junos OS version installed on the device is the same as the firmware version or later. To know the Junos OS version, issue the show version command.

  3. Ensure that the latest firmware version is downloaded to the Mini-PIM by verifying the Available version field. The Available version field should list the latest firmware version that was downloaded in Step 2.

    user@host > show system firmware

  4. Upgrade the firmware on the device.

    user@host > request system firmware upgrade pic fpc-slot <fpc-slot-number>

  5. Verify that the firmware is upgraded successfully.

    user@host > show system firmware

  6. Restart the FPC slot in which the VDSL PIM is installed.
    user@host > restart fpc <fpc-slot-number>
  7. Verify the firmware version. The Current Version field should show the latest firmware version and the Status should show OK.
    user@host > show system firmware
