Modifying the Zones Configuration for Security Devices

You can use the Zones section on the Modify Configuration page to modify the security zone configuration for a device. You can modify settings related to zone name, system services, protocols, application tracking, and associate screen to the zone.

Note: Refer to the Junos OS documentation (available at https://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.

Procedure

To modify the system log parameters:

  1. Select Devices > Security Devices.
    • The Security Devices page appears.

  2. Select the devices whose configuration you want to modify.
  3. From the More or right-click menu, select Configuration > Modify Configuration.
    • The Modify Configuration page appears.

  4. Click the Screens.
    • The Screens page appears.

  5. Modify the configuration according to the guidelines provided in Table 108.
  6. 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.
