1-Port T1/E1 Mini-Physical Interface Module (SRX-MP-1T1E1-R) Basic Configuration

To enable the 1-Port T1/E1 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 T1/E1 Mini-Physical Interface Module (SRX-MP-1T1E1-R) 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 (t1-1/0/0 or e1–1/0/0) 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 (if any).
  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).

Using the CLI

To perform basic configuration for the 1-Port T1/E1 Mini-PIM (for the T1 interface) and to configure network interfaces for the services gateway with the CLI:

  1. Verify that the T1/E1 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:

    For T1 interfaces:

    set interfaces t1-1/0/0 unit 0 family inet address interface address/destination prefix

    For E1 interfaces:

    set interfaces e1-1/0/0 unit 0 family inet address interface address/destination prefix

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

    For T1 interfaces:

    set security zones security-zone trust interfaces t1-1/0/0.0 host-inbound-traffic system-services all

    For E1 interfaces:

    set security zones security-zone trust interfaces e1-1/0/0.0 host-inbound-traffic system-services all

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

    For T1 interfaces:

    set security zones security-zone trust interfaces t1-1/0/0.0 host-inbound-traffic protocols all

    For E1 interfaces:

    set security zones security-zone trust interfaces e1-1/0/0.0 host-inbound-traffic protocols all

  6. Set security policies:

    set security policies default-policy permit-all

Note:

You can use the CLI commands set interfaces t1–1/0/0 or set interfaces e1–1/0/0 to enable the 1-Port T1/E1 Mini-PIM to function as a T1 or an E1 interface.
