Setting Up User and System Preferences

Depending on your privileges, the Preferences page displays either user settings or a combination of user settings and system settings. One or more of the following preference tabs appear when you open the Preferences page:

This topic describes:

Accessing the Preferences Page

To open the Preferences page, click in the Network Director banner and select Preferences as shown in Figure 7.

Figure 7: Accessing the Preferences Page

Accessing the Preferences
Page

The Preferences page opens with User Preferences as the default tab.

Choosing Server Time or Local Time

All users can specify whether Network Director displays local time or the server’s time in monitors and reports on the User Preferences tab. The default setting is to display local time. To change the setting to display the server’s time:

Procedure

  1. In the Preferences page, select Use Server Time from the list.
  2. Click OK to save your changes or click Cancel to close Preferences.

Specifying Search Preferences

Network Director indexes the device inventory data periodically to enable users to perform efficient searches. You can specify a time interval after which Network Director initiates the next indexing on the Search tab. You can also specify to stop indexing while devices are imported into Network Director. If you are running short of system memory, selecting this option helps save some memory and speed up the discovery and import of new devices. By default, this option is selected and the search index update interval is set to 900 seconds.

Enabling Import of Configuration Group Data from Ethernet Design

For Network Director to be able to import configuration group data.

Procedure

To enable the import of configuration group data:

  1. In the Preferences window, select the Config & Deploy tab.
  2. Select the Enable migration from Ethernet Design check box to enable import of configuration group data. By default this check box is not selected.
  3. Click Save to save and close the preferences.

    For detailed steps on importing configuration group data from Ethernet Design, see Importing Configuration Data from Junos OS Configuration Groups.

Specifying the Open Clos Server URL

Layer 3 Fabrics can expand your data center network to thousands of ports. Network Director uses Layer 3 protocols and Open Clos architecture to achieve this. Open Clos is typically installed on a separate system. You must specify the URL of the Open Clos system in Network Director before you can create and manage Layer 3 Fabrics.

Procedure

To specify the URL for the Open Clos server:

  1. Open the Config & Deploy tab in the Preferences window.
  2. Enter the URL to the system that is running Open Clos.
  3. Click OK.

Selecting the Approval Mode

Procedure

Use the Config & Deploy tab of System Preferences to configure the approval mode:

  1. Select the Manual Approval mode if you want an approver to review and approve the changes before they are deployed.

    By default, Auto Approval mode is selected. Use this mode if you want to deploy the configuration changes without a prior approval.

  2. If you select the Manual Approval mode, add one or more approvers’ e-mail addresses to notify the approvers every time a change request is submitted.
  3. Specify the rollback limit, which is the number of change requests that can be rolled back.

    The default value is 50. You can roll back a maximum of 1000 change requests.

  4. Specify the time after which a change request elapses after the time it was created.

    The minimum and maximum number of days that you can specify after which a change request elapses is 1 day and 365 days respectively. The change requests are highlighted in the following colors that indicate their overdue status.

    • Red color—Indicates that the change request is in overdue status.
    • Orange color—Indicates that the change request is due in less than 2 days.
    • Green color—Indicates that the change request is not yet due.
  5. Click OK to save the changes.

Note: Configuring the approval mode must be a one-time operation. Do not change the approval mode frequently.

To change the approval mode from Auto Approval to Manual Approval, you must either deploy or discard the device configuration changes. You are unable to change the approval mode to Manual Approval, or from Manual Approval to Auto Approval if local changes are in pending deployment state. The message: Do you want to retain the Change Request history? is displayed when you change the approval mode. If you choose to retain the change request history, all the existing change requests are retained by the system. Hence, even if you switch to the Auto Approval mode, you can view the change requests that were created in Manual Approval mode.

Note: While configuring the Manual Approval mode, you can specify any number of approvers. If you specify more than one approver while configuring the Manual Approval mode, after any approver accepts or rejects a proposed change, the change request is not listed for the other approvers and they cannot approve or reject the same change request.

Setting up Auto-resynchronization Preferences

If you enable auto-resynchronization in Network Director, any configuration changes made on the physical device, including out-of-band CLI commits and change-request updates, automatically trigger resychronization on the device.

Procedure

To set up auto-resynchronization:

  1. Select the Config & Deploy tab in the Preferences window.
  2. Select the option Purge unassigned system profiles after resynchronizing configuration, which removes unassigned profiles generated by Network Director after resynchronization or deletion of a device.

    Note: While upgrading Network Director, the profiles that are in unassigned state are not removed even if you select this option.

  3. Specify the time interval in Auto Resync TriggerWait Interval(sec). Network Director waits for this time interval before triggering auto-resynchronization.

    The default time interval is 120 seconds.

  4. Click OK.

Retaining Network Director Reports

By default, Network Director retains reports for 30 days. However, Network Administrators can change the retention period within the range 0 through 365 days. To change the setting, move the slider right or left on the Report tab of Preferences to the new setting. Click OK to save the setting.

Specifying Wireless Preferences

To manage Aruba wireless devices in your network, specify the URL to launch the Aruba’s wireless management platform, the Aruba Airwave application.

Sites with Aruba Airwave application licenses can launch the Airwave application from within Network Director by supplying the Airwave application URL. For information about setting up preferences to launch the Aruba Airwave application, see Linking to the Aruba Airwave Application.

To manage Juniper wireless devices in your network, specify the URL to launch Juniper’s wireless management platform, RingMaster.

Sites with RingMaster licenses can launch the RingMaster application from within Network Director by supplying the RingMaster URL. After typing the URL on the Wireless tab of Preferences, you can click Launch RingMaster in Build mode to load RingMaster into the main page. To enable launching RingMaster from within Network Director, simply type in the URL and click OK to save the setting.

Changing Monitor Mode Settings

The Monitoring tab of Preferences has three tabs under it. These are:

This section describes:

Disabling Data Collection for Monitors

Network Director internally gathers data for monitors by using a set of data collection processes. You can disable these data collectors if they do not pertain to your installation. For example, if you do not use Virtual Chassis, you can disable the data collection processes used for Virtual Chassis.

The data collection processes are divided into the following categories:

Procedure

One data collector can be used by multiple monitors. Likewise, some monitors can be supported by multiple data collectors. These data collectors are enabled by default. To ensure proper data collection, if you enable the equipment data collectors, you must also enable the traffic collectors..

To disable or reenable a data collector:

  1. Determine which monitors are used by the data collectors. Use Table 7 to determine the relationship between the data collectors and the monitors.

    • Click Enable to enable data collection for the selected devices.
    • Click Disable to disable data collection for the selected devices.

Specifying Database History Retention

To keep the database manageable, the system periodically checks the age of the records and retires those that have past an expiration date. By default, Network Director ages database records off at 90 days and runs a database cleanup every 6 hours.

Procedure

Use the Client Session History sub-tab to change the default values:

  1. Select from the lists new values.
    • Age of history records (in days) from 1 to 365 days.
    • Cleanup job frequency (in hours) from 1 through 24 hours.
  2. Click OK to save the changes.

Specifying the Data Learning Engine (DLE) Settings

The Data Learning Engine (DLE) is the component of Cloud Analytics Engine that enables Network Director to collect and analyze high-frequency statistics data from devices and to perform flow path analysis. For Network Director to use Cloud Analytics Engine, you must specify on what server or servers the Data Learning Engine (DLE) is running.

Each DLE supports up to a specific number of Compute Agents (CAs) running on network devices. If you have more CAs in a network than a single DLE can support, you might require multiple DLEs.

Procedure

Use the Data Learning Engine Settings sub-tab under the Monitoring tab to specify which Data Learning Engine (DLE) server or servers Network Director uses. You can also change the default ports used by the DLE.

To configure DLE in Network Director:

Changing Alarm Settings

Use the Fault tab to enable individual alarms, set the retention period for alarms, configure alarm notifications, configure threshold alarms, and to specify the number of events to keep for each alarm. The Fault tab has multiple sections, which you can expand and collapse by clicking the arrow next to the section title:

  • Global Settings, for configuring Faults settings such as global alarm notifications and alarm data retention.
  • Individual Alarms and Threshold Settings, for configuring settings for individual alarms and threshold alarms.

This section describes the following tasks that you can perform by using the Fault tab:

Configuring Global Alarm Notifications

You can configure global e-mail notifications to be sent when any alarm with notifications enabled is generated. To configure global e-mail notifications, enter the e-mail addresses to receive global alarm notifications in the Alarm Notifications Destinations field in the Global Settings section. Separate addresses with a comma (,). For information about enabling notification for an alarm, see Configuring Individual Alarm Notifications.

Retaining Alarm History

Use the No. of days to keep Alarm field in the Global Settings section to specify the number of days to keep alarm history. The default retention time is 120 days; but you can specify a period of 7 through 1000 days. Specifying a longer retention time consumes more database resources. To change the alarm retention duration, type a new value and click OK and Yes to confirm the change.

Specifying Event History

Use the Events/Alarm field in the Global Settings section to specify the number of event entries that are kept in the alarm history. The default setting for events is 20. To change the setting, type a new value and click OK and Yes to confirm the change.

Enabling Alarms

Procedure

Before You Begin

Ensure all devices are configured to send traps to Network Director. This task is performed for the devices in Deploy mode through Set SNMP Trap Configuration.

Use the Individual Alarms and Threshold Settings section to disable and re-enable individual alarms or all alarms. Alarms appear on both tabs in the section: Alarm Settings and Threshold Settings. Fault alarms are preconfigured and initially enabled. To enable or disable alarms:

  1. (Optional) Sort the alarms. By default, the list of alarms is sorted alphabetically within each category. You can also sort by description or alarm severity within a category by clicking a column heading.
  2. Review the alarms and either select the check box in the heading to select all of the alarms or select the check box for the individual alarms you want to enable. For a full description of each of the alarms, see Table 10.
  3. Click OK and Yes to confirm the alarm change.

Changing the Severity of Individual Alarms

You can change the severity of the alarms to match your corporate procedures and guidelines. For example, at your company a DoS attack might be considered a critical alarm, while Network Director has a default severity for DoS attacks as a major alarm. Alarms appear on both tabs in the Individual Alarms and Threshold Settings section: Alarm Settings and Threshold Settings.

Procedure

To change the severity of an alarm:

  1. Select the current severity in the Severity column. A list of the severity levels appear.
  2. Select the new severity level for the alarm.
  3. Click OK and Yes to confirm the change to the severity setting.

    To configure alarm notifications, see Configuring Individual Alarm Notifications.

Configuring Threshold Alarms

Threshold alarms are alarms that are generated when a monitored value crosses the configured threshold. They provide enhanced visibility into potential issues on the network. You configure and manage threshold alarms the same way as other alarms. You also have the option of setting the threshold level of individual threshold alarms.

Procedure

To edit the threshold of threshlod alarms:

  1. Select the Threshold Settings tab in the Individual Alarms and Threshold settings section of the Fault tab.
  2. Click Edit Settings in the Threshold Settings column of the alarm threshold you want to edit.
  3. Set the threshold in the window that opens.
  4. Click Save to save the new threshold.

    To configure alarm notifications, see Configuring Individual Alarm Notifications.

Configuring Individual Alarm Notifications

You can configure e-mail notifications to be sent when an individual alarm is generated. When you enable notification for an alarm, the notifications are sent to the e-mail addresses configured for the alarm and the addresses configured for global alarm notifications. Alarms appear on both tabs in the Individual Alarms and Threshold Settings section: Alarm Settings and Threshold Settings.

Procedure

To configure e-mail notification for an alarm name:

  1. Select the check box in the alarm’s Notification column.

    If you later want to disable notification for the alarm, clear the check box.

  2. Click Edit Notification in the Notification column. The Alarm Notification Details window opens.
  3. Type one or more e-mail addresses in the Notification Email Addresses box. Separate addresses with a comma (,).

    You can later edit the addresses to send notifications to different addresses.

  4. (Optional) Type a comment in the Comments box. This comment is included in the e-mail notification message.
  5. Click Save.

Modifying Data Center Synchronization Interval Using the Virtualization Tab

You can configure and manage data centers by using the Data Center View in Network Director. Network Director synchronizes data from the cloud infrastructure that is part of your data center every 24 hours. However, depending on the size of your data center network, you can modify this interval from the Virtualization tab in the Preferences page. Modify the interval by changing the Periodic Cloud Infrastructure Synchronization Interval (hours) field.

For data centers that use OpenStack as the cloud infrastructure provider, Network Director displays the links between hypervisors and switches only in the Data Center View. If you want to view the link details using the View Virtual Network Connectivity task, then you must select the Synchronize links from Topology to Virtualization application for OpenStack check box.

Note: Selecting the Synchronize links from Topology to Virtualization application for OpenStack check box might impact the performance of Network Director, while the synchronization is in process.
