Modifying the Physical Interfaces Configuration for Security Devices

You can use the Physical Interfaces section on the Modify Configuration page to view and modify physical interfaces on the device. You can also view, add, modify, or delete logical interfaces associated with the physical interfaces.

Note:

Refer to the Junos OS documentation (available at http://www.juniper.net/documentation/en_US/release-independent/junos/information-products/pathway-pages/junos/product/) for a particular release and device. There you can find detailed information on the configuration parameters for that device.

To modify physical interfaces:

  1. Select Devices > Security Devices.

    The Security Devices page appears.

  2. Select the devices to modify configuration.
  3. From the More or right-click menu, select Configuration > Modify Configuration.

    The Modify Configuration page appears.

  4. Click Physical Interfaces in the left-navigation menu.

    The Physical Interfaces section on the Modify Configuration page is displayed. The existing physical interfaces are displayed in a table. The actions that you can perform in this page are provided in Table 1.

  5. After modifying the configuration, you can cancel the changes, save the changes, preview the changes, or save the changes and deploy the configuration on the device. See Modifying the Configuration of Security Devices.

Guideline

IP Address

Enter an IPv4 address for the logical interface.

Subnet

Enter the subnet for the IPv4 address.

Primary

Select this check box to specify that the IPv4 address is the primary address of the protocol on the logical interface.
